OMAP: add TI TWL92330/Menelaus Power Management chip driver

Add Texas Instruments TWL92330/Menelaus Power Management chip driver.  This
includes voltage regulators, Dual slot memory card tranceivers and
real-time clock(RTC).

The support for RTC is integrated with this driver only; it is not separate
module.  Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic"
(1/N second) IRQs.  System wakeup alarms (from suspend-to-RAM) work too.

The battery keeps the RTC active over power off, so once you set clock
(rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will
behave as expected.

fbdev: extract fb_show_logo_line()

The Cell Broadband Engine contains a 64-bit PowerPC core with 2 hardware
threads (called PPEs) and 8 Synergistic Processing Engines (called SPEs).
When booting Linux, 2 penguins logos are shown on the graphical console by
the standard frame buffer console logo code.

To emphasize the existence of the SPEs (which can be used under Linux), we
added a second row of (smaller) helper penguin logos, one for each SPE.

A sample screenshot can be found at
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/debian-penguin-shot.png
(or on the ps3linux T-shirts we wore at OLS :-)

(blankinterval=0), "do_unblank_screen()" function returns without changing
"blank_state", and when "blank_state" is "blank_off", "do_blank_screen()

fb: epson1355fb: kill off dead sh support

The SH board that was the only user for this code was removed entirely from
the kernel quite some time ago, so there's no reason to leave the stubs in
place.  Additionally this driver was completely broken anyways, so there's
not really a lot of point in fixing it up either.

I can't imagine that this driver gets any testing on ARM either, given that
FB_BLANK_UNBLANKING doesn't exist, and kills the build regardless of which
platform is compiling.  This fixes that, too.

It wouldn't be a lot of work to finish the platform device conversion and
go with a generic 8-bit read/write_reg and kill off the architecture
dependence completely, should someone have any use for this driver.

fbdev: fbcon: console unregistration from unregister_framebuffer

This allows for proper console unregistration via the VT layer, and updates
the FB layer to use it.  This makes debugging new console drivers much easier,
since you can properly clean them up before unloading.

[adaplas]
unregister_framebuffer() is typically called as part of the driver's
module_exit(). Doing so otherwise will freeze the machine as the VT layer is
holding reference counts on fbcon, and fbcon on the driver.  With this change,
it allows unregister_framebuffer() to be called safely anywhere as needed.

Additions from the original:  If multiple drivers are used by fbcon, and if
one of them unregisters, a driver will take over the consoles vacated by the
outgoing one (via set_con2fb_map).   Once only the outgoing driver remains,
then fbcon will unbind from the VT layer (if CONFIG_HW_CONSOLE_UNBINDING is
set to y).

It is important that these drivers implement fb_open() and fb_release()
just to ensure that no other process is using the driver. Likewise, these
drivers _must_ check the return value of unregister_framebuffer().

fbcon: Revise primary device selection

Use set_con2fb_map() to select the primary display driver instead of using
unbind_con_driver() and bind_con_driver().  Using the former is much simpler
and safer than the current one.

fbcon: set_con2fb_map fixes

set_con2fb_map() has regressed for some time.  Using fbcon=map:01, for
example, works only if there is only 1 working framebuffer. Trying to do a
set_con2fb_map() on a non-allocated vc will freeze the system.

- ensure that succeeding drivers after the first gets mapped to the console
- remove fbcon_preset_display() and modify fbcon_set_display() to include the
  former's functionality
- ensure that binding and unbinding succeeds if multiple drivers are mapped to

Allow fbcon to select the primary display adapter using the

rtc-rs5c372 becomes a new-style i2c driver

Convert rtc-rs5c372 to be a "new style" I2C driver, and update the
Kconfig text to be more complete..

Verified on an OMAP H4 development platform, along with a board
init patch to declare its rv5c387a device.

Only one defconfig -- powerpc/linkstation -- uses this driver; but
several other platforms use it, just without defconfig support.

Such platforms need to be converted so (a) their I2C adapter driver
supports new-style drivers, and (b) board init code declares this
I2C device.

rtc-ds1307 cleanups

This updates the rtc-ds1307 driver so that converting it to a "new style"
driver (driver model, not legacy i2c model) will involve fewer changes.

 - Use pointer to i2c_client almost everywhere, so that it's easy
   to let the i2c core create that object;

 - Avoid using i2c_client.adapter, since that field is redundant and
   thus may go away (same object as i2c_client.dev.parent).

 - Extend type enum to include various RTCs this is expected to
   work with, and include register support for them.

It also cleans up the support for multiple chip types, and fixes a
glitch that could appear with an un-initialized RTC.

Couple fixes to fs/ecryptfs/inode.c

Following was uncovered by compiling the kernel with '-W' flag:

  CC [M]  fs/ecryptfs/inode.o
fs/ecryptfs/inode.c: In function ‘ecryptfs_lookup’:
fs/ecryptfs/inode.c:304: warning: comparison of unsigned expression < 0 is always false
fs/ecryptfs/inode.c: In function ‘ecryptfs_symlink’:
fs/ecryptfs/inode.c:486: warning: comparison of unsigned expression < 0 is always false

Function ecryptfs_encode_filename() can return -ENOMEM, so change the
variables to plain int, as in the first case the only real use actually
expects int, and in latter case there is no use beoynd the error check.

knfsd: nfsd: enforce per-flavor id squashing

Allow root squashing to vary per-pseudoflavor, so that you can (for example)
allow root access only when sufficiently strong security is in use.
