-Subject: [PATCH] bzip2/lzma: remove nasty uncompressed size hack in pre-boot environment
-
-decompress_bunzip2 and decompress_unlzma have a nasty hack that subtracts
-4 from the input length if being called in the pre-boot environment.
-
-This is a nasty hack because it relies on the fact that flush = NULL only
-when called from the pre-boot environment (i.e.
-arch/x86/boot/compressed/misc.c).  initramfs.c/do_mounts_rd.c pass in a
-flush buffer (flush != NULL).
-
-This hack prevents the decompressors from being used with flush = NULL by
-other callers unless knowledge of the hack is propagated to them.
-
-This patch removes the hack by making decompress (called only from the
-pre-boot environment) a wrapper function that subtracts 4 from the input
-length before calling the decompressor.

-From: Phillip Lougher <phillip@lougher.demon.co.uk>
-Date: Tue, 6 Oct 2009 04:04:15 +0100
-Subject: [PATCH] Squashfs: add a decompressor framework
-
-This adds a decompressor framework which allows multiple compression
-algorithms to be cleanly supported.
-
-Also update zlib wrapper and other code to use the new framework.

-Subject: [PATCH] Squashfs: add decompressor entries for lzma and lzo
-
-Add knowledge of lzma/lzo compression formats to the decompressor
-framework.  For now these are added as unsupported.  Without
-these entries lzma/lzo compressed filesystems will be flagged as
-having unknown compression which is undesirable.

-Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
-
-Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
-specify they need the unlzma code.  Normally decompress_unlzma.c is
-compiled with __init and unlzma is not exported to modules.

-+Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
-+however from programming point of view there is nothing AMBA specific we use.
-+
-+Standard AMBA drivers are platform specific, have hardcoded addresses and use
-+AMBA standard fields like CID and PID.
-+
-+In case of Broadcom's cards every device consists of:
-+1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
-+   as standard AMBA device. Reading it's CID or PID can cause machine lockup.
-+2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
-+   and PIDs (0x103BB369), but we do not use that info for anything. One of that
-+   devices is used for managing Broadcom specific core.
-+
-+Addresses of AMBA devices are not hardcoded in driver and have to be read from
-+EPROM.
-+
-+In this situation we decided to introduce separated bus. It can contain up to
-+16 devices identified by Broadcom specific fields: manufacturer, id, revision
-+and class.

-Subject: [PATCH] MIPS: fix loading of modules with unresolved weak symbols
-
-Loading of modules with unresolved weak symbols fails on MIPS
-since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.
-
-Modules: handle symbols that have a zero value
-
-The module subsystem cannot handle symbols that are zero.  If symbols
-are present that have a zero value then the module resolver prints out a
-message that these symbols are unresolved.
-
-We have to use IS_ERR_VALUE() to check that a symbol has been resolved
-or not.

-This patch updates kernel part of kexec for MIPS platform to support
-kdump, 64-bit, SMP and simplify code adaptation to new boards. It does
-the following:
-
-- hooks for machine-specific actions are introduced
-(_machine_kexec_prepare,
-  _machine_kexec_shutdown, _machine_crash_shutdown);
-- kexec reboot on SMP machine is implemented;
-- add boot parameters passing to new kernel (array kexec_args[] is
-copied to
-  registers a0-a3 on reboot );
-- crash dump functionality is added (boot kernel with non-default physical
-  start, parse "crashkernel=..." command line parameter, copy_oldmem_page()
-  is implemeted to read memory dump after reboot-on-crashi,
-crash_setup_regs()
-  is updated to correctly store registers on crash);
-
-kexec/kdump funtionality was tested on several Cavium Octeon boards
-(mips64 SMP). The way we do it was the following:
-- _machine_kexec_prepare was find kexec segment with command line and
-save it's pointed into internal bootloader structure.
-- _machine_kexec_shutdown was used to stop boards IO and make all non-boot
-CPUs spin in function relocated_kexec_smp_wait()
-- _machine_crash_shutdown just calls default_machine_crash_shutdown()
-We tested 1) 'common' kexec reboot (by 'kexec -e'), 2) kexec-on-panic
-('kexec -p ...') and 3) access to/proc/vmcore (with gdb).

-GCC 4.4.x looks to be adding support for generating out-of-line register
-saves/restores based on:
-
-http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
-
-This breaks the kernel build as we'd have to link with libgcc to get the
-implementation of the register save/restores.
-
-To workaround this issue, we just stole the save/restore code from gcc
-and simplified it down for our needs (integer only).  We only do this if
-PPC32 as gcc makes believe the linker on ppc64 will deal with this and
-only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
-
-Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>

-If someone using cutting edge toolchains for ppc64 could test and make
-sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
-nice.

-+ * Opcode notes:
-+ *
-+ * BRANCH     The set of branches constituting a single choice are hooked
-+ *            together with their "next" pointers, since precedence prevents
-+ *            anything being concatenated to any individual branch.  The
-+ *            "next" pointer of the last BRANCH in a choice points to the
-+ *            thing following the whole choice.  This is also where the
-+ *            final "next" pointer of each individual branch points; each
-+ *            branch starts with the operand node of a BRANCH node.
-+ *
-+ * BACK               Normal "next" pointers all implicitly point forward; BACK
-+ *            exists to make loop structures possible.
-+ *
-+ * STAR,PLUS  '?', and complex '*' and '+', are implemented as circular
-+ *            BRANCH structures using BACK.  Simple cases (one character
-+ *            per match) are implemented with STAR and PLUS for speed
-+ *            and to minimize recursive plunges.
-+ *
-+ * OPEN,CLOSE ...are numbered at compile time.

-+
-+/*
-+ * A node is one char of opcode followed by two chars of "next" pointer.
-+ * "Next" pointers are stored as two 8-bit pieces, high order first.  The
-+ * value is a positive offset from the opcode of the node containing it.
-+ * An operand, if any, simply follows the node.  (Note that much of the
-+ * code generation knows about this implicit relationship.)
-+ *
-+ * Using two bytes for the "next" pointer is vast overkill for most things,

-+          minixfs or pramfs.

-+2005-06-30  Eric Lammerts <eric@lammerts.org>
-+
-+      * fix for an oops when overwriting a binary thats beeing
-+          executed.
-+
-+2005-06-09    <mk@mary>
-+
-+      * Renamed overlay to mini_fo-overlay.
-+
-+      * Added mini_fo-merge script to allow merging of storage and base
-+      after making modifications.
-+
-+2005-05-22  root  <mk@mary>
-+
-+      * Added overlay script that allows to easily mount mini_fo ontop
-+      of a given base directory
-+
-+2005-05-10    <mk@mary>
-+
-+      * inode.c: xattr functions return -EOPNOSUPP instead of
-+          -ENOSUPP, what confuses "ls -l"
-+
-+      * Changed license from LGPL to GPL.
-+
-+2005-05-08  root  <mk@mary>
-+
-+      * Makefile: clean it up and added make install and make
-+          uninstall.
-+
-+2005-05-06    <mk@mary>
-+
-+      * merged devel branch back to main. [v0-6-0-pre3]
-+
-+      * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+      * ioctl: removed fist_ioctl stuff, that is not needed for
-+          now.
-+
-+2005-05-03    <mk@mary>
-+
-+      * file.c: simplified mini_fo_open and mini_fo_setattr using
-+          new state changing functions. [devel-0-0-17]
-+
-+      * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+          mini_fo_inode revalidate.
-+
-+      * inode.c: found an other bug in mini_fo_getattr. States are not
-+        reliable in this function, as a file can be opened, unlinked and
-+        the getattr function called. This results in a deleted dentry
-+        with an inode. Fix is to ignore states and simply use the inode
-+        available.
-+
-+2005-04-29    <mk@mary>
-+
-+      * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+      * file.c: do not use mini_fo_lock so the generic version is
-+          used (I guess).
-+
-+      * inode.c: getattr, never call getattr on lower files, as this
-+          will cause the inum to change.
-+
-+      * inode.c: rename_reg_file renamed to rename_nondir, as it
-+          doesn't matter as long it't not a dir. Removed all
-+          rename_dev_file etc.
-+
-+      * tagged as devel-0-0-15
-+
-+      * inode.c: added support for chosing support for extended
-+          attrs at compile time by XATTR define in mini_fo.h .
-+
-+      * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+          lower again, what avoids inode number changes that confused
-+          rm again. This is the proper solution.
-+
-+2005-04-24    <mk@mary>
-+
-+      * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+      * inode.c: fixed mini_fo_getattr to not change the inode
-+          number, even if lower files change.
-+
-+      * super.c: fixed a bug that caused deleted base file to show
-+          up suddenly after some time, or after creating a special
-+          file. The problem was that after some time or after special
-+          file creating sync_sb_inodes is called by the vfs, that
-+          called our mini_fo_put_inode. There was (wrongly) called
-+          __meta_put_lists, that nuked the lists, although the inode
-+          was going to continue its life. Moving __meta_put_lists to
-+          mini_fo_clear_inode, where an inode is really destroyed,
-+          solved the problem.
-+
-+
-+2005-04-23    <mk@mary>
-+
-+      * state.c, aux.c: more cleaning up and
-+          simplifications. [devel-0-0-13]
-+
-+      * inode.c: implemented mini_fo_getattr, that was required for
-+          2.6 because inode_revalidate has been remove there, and the
-+        old "du" bug returned.
-+
-+
-+2005-04-20    <mk@mary>
-+
-+      * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+          in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19    <mk@mary>
-+
-+      * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+          not to be deleted properly and therefore the fs filled up
-+          untill no memory was left. [devel-0-0-12]
-+
-+      * Added basic hard link support. This means that creating
-+          hardlinks will work, but existing ones will be treated as
-+          individual files. [devel-0-0-11]
-+
-+2005-04-17    <mk@mary>
-+
-+      * Bugfixes
-+
-+2005-04-13  root  <mk@mary>
-+
-+      * Added file state.c for the state transition
-+          functions. Doesn't work very well yet, though...
-+
-+2005-04-12    <mk@mary>
-+
-+      * Porting to 2.6 started, which is easier than expected, also
-+          due to Olivier previous work.
-+
-+2005-04-08    <mk@mary>
-+
-+      * Fixed the bug that caused du to return invalid sizes of
-+          directory trees. The problem was that
-+          mini_fo_inode_revalidate didn't always copy the attributes
-+          from the base inode properly.
-+
-+2005-04-01  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Merged devel branch back to main trunk and updated the
-+          RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Fixed some bugs in rename_reg_file, that only showed up in
-+          the kernel compile test. Kernel compiles cleanly ontop of
-+          mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Many, many directory renaming bugfixes and a lot of other
-+          cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Finished implementing lightweight directory renaming. Some
-+          basic testing indicates it works fine.
-+        Next is to implement testcases for the testsuite and confirm
-+          everything is really working ok.
-+
-+2005-03-18  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Finished implementing meta.c stuff required for directory
-+          renaming.
-+
-+2005-03-17  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Fixed all compile warnings + an extremly old bug that
-+          somehow crept in while reworking the wol stuff to the META
-+          system. Turning on -Werror again... :-)
-+
-+      * Fixed some bugs in the new rename_reg_file function.
-+
-+      * Rewrote mini_fo rename and split it into several
-+          subfunctions, that handle the different types
-+          seperately. Rewrote the regular file function aswell, as it
-+          was implemented somewhat inefficient.
-+
-+2005-03-16  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Implemented new META subsystem, removed old WOL stuff in favor
-+        if it.
-+
-+      * After some basic testing everything seems ok...
-+
-+2005-03-11  Markus Klotzbuecher  <mk@chasey>

-+      * Renaming a non regular file caused trouble because I always
-+        tried to copy the contents. Now I only do this for regular
-+        files. mini_fo_rename still isn't implemented properly, renaming
-+        of device files, symlinks etc. results in a empty regular file
-+        instead of the proper type.
-+
-+      * Directory renaming suddenly works! What a surprise! I guess
-+          this is because renaming is implemented as making a copy and
-+          removing the original. Still this might not work
-+          everywhere...

-+
-+      * Bugfix, when a mini_fo directory that exists in storage
-+        (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+        possibly existing WOL file contained in it needs to be
-+        deleted too.
-+
-+      * Starting cleanup: defined state names in order to get rid of
-+          the state numbers.
-+
-+2005-03-08  Markus Klotzbuecher  <mk@chasey>
-+
-+      * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+      * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+          DEL_REWRITTEN the hash was calculated from the base dentry,
-+          which was wrong and and caused assertions in
-+          __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21    <mk@mary>
-+
-+      * Implemented directory deleting (inode.c)
-+
-+      * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22    <mk@mary>
-+
-+      * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+      * Created a new and hopefully more informative README
-+
-+      * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+      * Fix: owner and group where not correctly copied from base to
-+          storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+      * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+      * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+      * Implementation of mini_fo_mknod and mini_fo_rename, support
-+          for device files.

-+          add given suffix to storage directory and the mount
-+          point. This is usefull for overlaying one base directory

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+    # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+    # make install
-+
-+or uninstall with
-+
-+    # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+   mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+                            <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+    # insmod mini_fo.o for a 2.4 kernel or
-+
-+    # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+    # mkdir /tmp/sto
-+    # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+    # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+    # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+    # cd /tmp/sto
-+    # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.

-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+    # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release:      mini_fo-0.6.1 (v0-6-1)
-+Date:         21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+  README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+  existing links in the base file system will be treated as if they
-+  were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+  many vital mini_fo parts such as the old whiteout list code which
-+  has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+  directory is renamed via the mini_fo filesystem this will no longer
-+  result in a complete copy in storage, instead only one empty
-+  directory will be created. All base filed contained in the original
-+  directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+  of many features. This release contains several bugfixes related to
-+  directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+  fact tha that "mv" is smart: if the classic rename doesn't work it
-+  will assume that source and target file are on different fs and will
-+  copy the directory and try to remove the source directory. Until
-+  directory removing wasn't implemented, it would fail to do this and
-+  rollback.
-+  So, directory renaming works for now, but it doesn't yet do what you
-+  would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+  happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-    in routed mode, we don't have a hardware address so netdev_ops doesnt
-    need to validate our hardware address via .ndo_validate_addr

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+      pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+      err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+      err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+      mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in                  = The SPI data-IN GPIO pin number.
-+gpio_data_out                 = The SPI data-OUT GPIO pin number.
-+gpio_clock                    = The SPI Clock GPIO pin number.
-+gpio_chipselect                       = The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow     = Boolean. If 0, Chipselect is active-HIGH.
-+                                If 1, Chipselect is active-LOW.
-+spi_mode                      = The SPI data mode. Can be 0-3.
-+spi_delay                     = Enable all delays in the lowlevel bitbanging.
-+max_bus_speed                 = The maximum SPI bus speed. In Hertz.
-+
-+register                      = Not a configuration parameter.
-+                                Used to register the configured card
-+                                with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow     = 1             (CS active-LOW)
-+spi_mode                      = 0             (SPI_MODE_0)
-+spi_delay                     = 1             (enabled)
-+max_bus_speed                 = 5000000       (5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.

-X-Git-Tag: next-20090817~86^2~1^6
-X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fnext%2Flinux-next.git;a=commitdiff_plain;h=369842658a36bcea28ecb643ba4bdb53919330dd

-ARM: 5677/1: ARM support for TIF_RESTORE_SIGMASK/pselect6/ppoll/epoll_pwait
-
-This patch adds support for TIF_RESTORE_SIGMASK to ARM's
-signal handling, which allows to hook up the pselect6, ppoll,
-and epoll_pwait syscalls on ARM.
-
-Tested here with eabi userspace and a test program with a
-deliberate race between a child's exit and the parent's
-sigprocmask/select sequence. Using sys_pselect6() instead
-of sigprocmask/select reliably prevents the race.
-
-The other arch's support for TIF_RESTORE_SIGMASK has evolved
-over time:
-
-In 2.6.16:
-- add TIF_RESTORE_SIGMASK which parallels TIF_SIGPENDING
-- test both when checking for pending signal [changed later]
-- reimplement sys_sigsuspend() to use current->saved_sigmask,
-  TIF_RESTORE_SIGMASK [changed later], and -ERESTARTNOHAND;
-  ditto for sys_rt_sigsuspend(), but drop private code and
-  use common code via __ARCH_WANT_SYS_RT_SIGSUSPEND;
-- there are now no "extra" calls to do_signal() so its oldset
-  parameter is always &current->blocked so need not be passed,
-  also its return value is changed to void
-- change handle_signal() to return 0/-errno
-- change do_signal() to honor TIF_RESTORE_SIGMASK:
-  + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
-    is set
-  + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
-  + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
-    clear it and restore the sigmask
-- hook up sys_pselect6() and sys_ppoll()
-
-In 2.6.19:
-- hook up sys_epoll_pwait()
-
-In 2.6.26:
-- allow archs to override how TIF_RESTORE_SIGMASK is implemented;
-  default set_restore_sigmask() sets both TIF_RESTORE_SIGMASK and
-  TIF_SIGPENDING; archs need now just test TIF_SIGPENDING again
-  when checking for pending signal work; some archs now implement
-  TIF_RESTORE_SIGMASK as a secondary/non-atomic thread flag bit
-- call set_restore_sigmask() in sys_sigsuspend() instead of setting
-  TIF_RESTORE_SIGMASK
-
-In 2.6.29-rc:
-- kill sys_pselect7() which no arch wanted
-
-So for 2.6.31-rc6/ARM this patch does the following:
-- Add TIF_RESTORE_SIGMASK. Use the generic set_restore_sigmask()
-  which sets both TIF_SIGPENDING and TIF_RESTORE_SIGMASK, so
-  TIF_RESTORE_SIGMASK need not claim one of the scarce low thread
-  flags, and existing TIF_SIGPENDING and _TIF_WORK_MASK tests need
-  not be extended for TIF_RESTORE_SIGMASK.
-- sys_sigsuspend() is reimplemented to use current->saved_sigmask
-  and set_restore_sigmask(), making it identical to most other archs
-- The private code for sys_rt_sigsuspend() is removed, instead
-  generic code supplies it via __ARCH_WANT_SYS_RT_SIGSUSPEND.
-- sys_sigsuspend() and sys_rt_sigsuspend() no longer need a pt_regs
-  parameter, so their assembly code wrappers are removed.
-- handle_signal() is changed to return 0 on success or -errno.
-- The oldset parameter to do_signal() is now redundant and removed,
-  and the return value is now also redundant and changed to void.
-- do_signal() is changed to honor TIF_RESTORE_SIGMASK:
-  + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
-    is set
-  + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
-  + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
-    clear it and restore the sigmask
-- Hook up sys_pselect6, sys_ppoll, and sys_epoll_pwait.

-Subject: Fix the VFP handling on the Feroceon CPU
-X-Git-Url: http://www.linux-arm.org/git?p=linux-2.6.git;a=commitdiff_plain;h=85d6943af50537d3aec58b967ffbd3fec88453e9;hp=26584853a44c58f3d6ac7360d697a2ddcd1a3efa
-
-Fix the VFP handling on the Feroceon CPU
-
-This CPU generates synchronous VFP exceptions in a non-standard way -
-the FPEXC.EX bit set but without the FPSCR.IXE bit being set like in the
-VFP subarchitecture 1 or just the FPEXC.DEX bit like in VFP
-subarchitecture 2. The main problem is that the faulty instruction
-(which needs to be emulated in software) will be restarted several times
-(normally until a context switch disables the VFP). This patch ensures
-that the VFP exception is treated as synchronous.
