It is possible for ide-cd to ignore ide_error()'s return value under
some circumstances. Workaround it in ide_intr() and ide_timer_expiry()
by checking if there is a device/port reset pending currently.

ide: fix 40-wire cable detection for TSST SH-S202* ATAPI devices (v2)
Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk:
commit
8588a2b732928b343233af9b1855705b8286bed4
("ide: add SH-S202J to ivb_list[]")
We also later added support for more such devices in:
commit
e97564f362a93f8c248246c19828895950341252
("ide: More TSST drives with broken cable detection")
and in:

3ced5c49bd2d1f2c7f769e3a54385883de63a652
("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]")
It turns out that such devices lack cable detection altogether
(which in turn results in incorrect detection of 40-wire cables
by our current cable detection strategy) so always handle them
by trusting host-side cable detection only.

futex: setup writeable mapping for futex ops which modify user space data

drm: Round size of SHM maps to PAGE_SIZE
Currently, userspace can fail to obtain the SAREA mapping (among other
reasons) if it passes SAREA_MAX to drmAddMap without aligning it to the
page size. This breaks for example on PowerPC with 64K pages and radeon
despite the kernel radeon actually doing the right rouding in the first
place.
The way SAREA_MAX is defined with a bunch of ifdef's and duplicated
between libdrm and the X server is gross, ultimately it should be
retrieved by userspace from the kernel, but in the meantime, we have
plenty of existing userspace built with bad values that need to work.
This patch works around broken userspace by rounding the requested size
in drm_addmap_core() of any SHM map to the page size. Since the backing
memory for SHM maps is also allocated within addmap_core, there is no
danger of adjacent memory being exposed due to the increased map size.
The only side effect is that drivers that previously tried to create or
access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL),
will now succeed at the cost of a little bit more memory used if that
happens to be when the map is created.

TPM: get_event_name stack corruption
get_event_name uses sprintf to fill a buffer declared on the stack. It fills
the buffer 2 bytes at a time. What the code doesn't take into account is that
sprintf(buf, "%02x", data) actually writes 3 bytes. 2 bytes for the data and
then it nul terminates the string. Since we declare buf to be 40 characters
long and then we write 40 bytes of data into buf sprintf is going to write 41
characters. The fix is to leave room in buf for the nul terminator.

PCI PM: Fix initialization and kexec breakage for some devices
Recent PCI PM changes introduced a bug that causes some devices to be
mishandled after kexec and during early initialization. The failure
scenario in the kexec case is the following:
* Assume a PCI device is not power-manageable by the platform and has
PCI_PM_CTRL_NO_SOFT_RESET set in PMCSR.
* The device is put into D3 before kexec (using the native PCI PM).
* After kexec, pci_setup_device() sets the device's power state to
PCI_UNKNOWN.
* pci_set_power_state(dev, PCI_D0) is called by the device's driver.
* __pci_start_power_transition(dev, PCI_D0) is called and since the
device is not power-manageable by the platform, it causes
pci_update_current_state(dev, PCI_D0) to be called. As a result
the device's current_state field is updated to PCI_D3, in
accordance with the contents of its PCI PM registers.
* pci_raw_set_power_state() is called and it changes the device power
state to D0. *However*, it should also call pci_restore_bars() to
reinitialize the device, but it doesn't, because the device's
current_state field has been modified earlier.
To prevent this from happening, modify pci_platform_power_transition()
so that it doesn't use pci_update_current_state() to update the
current_state field for devices that aren't power-manageable by the
platform. Instead, this field should be updated directly for devices
that don't support the native PCI PM.

futex: setup writeable mapping for futex ops which modify user space data
The futex code installs a read only mapping via get_user_pages_fast()
even if the futex op function has to modify user space data. The
eventual fault was fixed up by futex_handle_fault() which walked the
VMA with mmap_sem held.
After the cleanup patches which removed the mmap_sem dependency of the
futex code commit
4dc5b7a36a49eff97050894cf1b3a9a02523717 (futex:
clean up fault logic) removed the private VMA walk logic from the
futex code. This change results in a stale RO mapping which is not
fixed up.
Instead of reintroducing the previous fault logic we set up the
mapping in get_user_pages_fast() read/write for all operations which
modify user space data. Also handle private futexes in the same way
and make the current unconditional access_ok(VERIFY_WRITE) depend on
the futex op.

cifs: fix pointer initialization and checks in cifs_follow_symlink (try #4)
This is the third respin of the patch posted yesterday to fix the error
handling in cifs_follow_symlink. It also includes a fix for a bogus NULL
pointer check in CIFSSMBQueryUnixSymLink that Jeff Moyer spotted.
It's possible for CIFSSMBQueryUnixSymLink to return without setting
target_path to a valid pointer. If that happens then the current value
to which we're initializing this pointer could cause an oops when it's
kfree'd.
This patch is a little more comprehensive than the last patches. It
reorganizes cifs_follow_link a bit for (hopefully) better readability.
It should also eliminate the uneeded allocation of full_path on servers
without unix extensions (assuming they can get to this point anyway, of
which I'm not convinced).
On a side note, I'm not sure I agree with the logic of enabling this
query even when unix extensions are disabled on the client. It seems
like that should disable this as well. But, changing that is outside the
scope of this fix, so I've left it alone for now.

Fix oops on close of hot-unplugged FTDI serial converter
Commit
c45d6320 ("fix reference counting of ftdi_private") stopped
ftdi_sio_port_remove() from directly freeing the port-private data, with
the intention if the port was still open, it would be freed when
ftdi_close() is eventually called and releases the last refcount on the
structure.
That's all very well, but ftdi_sio_port_remove() still contains a call
to usb_set_serial_port_data(port, NULL) -- so by the time we get to
ftdi_close() for the port which was unplugged, it _still_ oopses on
dereferencing that NULL pointer, as it did before (and does in 2.6.29).
The fix is just not to clear the private data in ftdi_sio_port_remove().
Then the refcount is properly reduced to zero when the final kref_put()
happens in ftdi_close().
Remove a bogus comment too, while we're at it. And stop doing things
inside "if (priv)" -- it must _always_ be there.

[ARM] Double check memmap is actually valid with a memmap has unexpected holes V2
pfn_valid() is meant to be able to tell if a given PFN has valid memmap
associated with it or not. In FLATMEM, it is expected that holes always
have valid memmap as long as there is valid PFNs either side of the hole.
In SPARSEMEM, it is assumed that a valid section has a memmap for the
entire section.
However, ARM and maybe other embedded architectures in the future free
memmap backing holes to save memory on the assumption the memmap is never
used. The page_zone linkages are then broken even though pfn_valid()
returns true. A walker of the full memmap must then do this additional
check to ensure the memmap they are looking at is sane by making sure the
zone and PFN linkages are still valid. This is expensive, but walkers of
the full memmap are extremely rare.
This was caught before for FLATMEM and hacked around but it hits again for
SPARSEMEM because the page_zone linkages can look ok where the PFN linkages
are totally screwed. This looks like a hatchet job but the reality is that
any clean solution would end up consumning all the memory saved by punching
these unexpected holes in the memmap. For example, we tried marking the
memmap within the section invalid but the section size exceeds the size of
the hole in most cases so pfn_valid() starts returning false where valid
memmap exists. Shrinking the size of the section would increase memory
consumption offsetting the gains.
This patch identifies when an architecture is punching unexpected holes
in the memmap that the memory model cannot automatically detect and sets
ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx
which is the model sub-architecture this has been reported on but may expand
later. When set, walkers of the full memmap must call memmap_valid_within()
for each PFN and passing in what it expects the page and zone to be for
that PFN. If it finds the linkages to be broken, it assumes the memmap is
invalid for that PFN.

powerpc/ftrace: Fix constraint to be early clobber
After upgrading my distcc boxes from gcc 4.2.2 to 4.4.0, the function

The issue is that gcc used the same register for an output as it did for
an input in an asm statement. I first thought this was a bug in gcc and
reported it. I was notified that gcc was correct and that the output had
to be flagged as an "early clobber".

bonding: fix link down handling in 802.3ad mode
One of the purposes of bonding is to allow for redundant links, and failover
correctly if the cable is pulled. If all the members of a bonded device have
no carrier present, the bonded device itself needs to report no carrier present
to user space so management tools (like routing daemons) can respond.
Bonding in 802.3ad mode does not work correctly for this because it incorrectly
chooses a link that is down as a possible aggregator.

If bridge is configured with no STP and forwarding delay of 0 (which
is typical for virtualization) then when link starts it will flood all
packets for the first 20 seconds.
This bug was introduced by a combination of earlier changes:
* forwarding database uses hold time of zero to indicate
user wants to always flood packets
* optimzation of the case of forwarding delay of 0 avoids the initial
timer tick
The fix is to just skip all the topology change detection code if
kernel STP is not being used.

ipconfig: handle case of delayed DHCP server
If a DHCP server is delayed, it's possible for the client to receive the
DHCPOFFER after it has already sent out a new DHCPDISCOVER message from
a second interface. The client then sends out a DHCPREQUEST from the
second interface, but the server doesn't recognize the device and
rejects the request.
This patch simply tracks the current device being configured and throws
away the OFFER if it is not intended for the current device. A more
sophisticated approach would be to put the OFFER information into the
struct ic_device rather than storing it globally.

netpoll: don't dereference NULL dev from np
It looks like the dev in netpoll_poll can be NULL - at lease it's
checked at the function beginning. Thus the dev->netde_ops dereference
looks dangerous.

page-writeback: fix the calculation of the oldest_jif in wb_kupdate()
wb_kupdate() function has a bug on linux-2.6.30-rc5. This bug causes
generic_sync_sb_inodes() to start to write inodes back much earlier than
our expectations because it miscalculates oldest_jif in wb_kupdate().
