This patch fixes 2 issues with the LZO decompressor:

- It doesn't handle the case where a block isn't compressed at all.  In
  this case, calling lzo1x_decompress_safe will fail, so we need to just
  use memcpy() instead (the upstream LZO code does something similar)

- Since commit 54291362 ("initramfs: add
  missing decompressor error check") , the decompressor return code is
  checked in the init/initramfs.c The LZO decompressor didn't return the
  expected value, causing the initramfs code to falsely believe a
  decompression error occured

If a futex key happens to be located within a huge page mapped
MAP_PRIVATE, get_futex_key() can go into an infinite loop waiting for a
page->mapping that will never exist.

See https://bugzilla.redhat.com/show_bug.cgi?id=552257 for more details
about the problem.

This patch makes page->mapping a poisoned value that includes
PAGE_MAPPING_ANON mapped MAP_PRIVATE.  This is enough for futex to
continue but because of PAGE_MAPPING_ANON, the poisoned value is not
dereferenced or used by futex.  No other part of the VM should be
dereferencing the page->mapping of a hugetlbfs page as its page cache is
not on the LRU.

This patch fixes the problem with the test case described in the bugzilla.

When the temperature exceeds 32767 milli-degrees the temperature overflows

Description of patch:
---------------------

This is a patch for the EFI framebuffer driver to enable the framebuffer
of the NVIDIA 9400M as found in MacBook Pro (MBP) 5,1 and up.  The
framebuffer of the NVIDIA graphic cards are located at the following
addresses in memory:

9400M:    0xC0010000
9600M GT: 0xB0030000

The patch delivered right here only provides the memory location of the
framebuffer of the 9400M device.  The 9600M GT is not covered.  It is
assumed that the 9400M is used when powered up the MBP.

The information which device is currently powered and in use is stored in
the 64 bytes large EFI variable "gpu-power-prefs".  More specifically,
byte 0x3B indicates whether 9600M GT (0x00) or 9400M (0x01) is online.

The PCI bus IDs are the following:
9400M:    PCI 03:00:00
9600M GT: PCI 02:00:00

The EFI variables can be easily read-out and manipulated with "rEFIt", an
MBP specific bootloader tool.  For more information on how handle rEFIt
and EFI variables please consult "http://refit.sourceforge.net" and
"http://ubuntuforums.org/archive/index.php/t-1076879.html".

IMPORTANT NOTE: The information on how to activate the 9400M device given
at "ubuntuforums.org" is not correct, since it states

gpu-power-prefs[0x3B] = 0x00 -> 9400M (PCI 02:00:00)
gpu-power-prefs[0x3B] = 0x01 -> 9600M GT (PCI 03:00:00)

Actually, the assignment of the values and the PCI bus IDs are swapped.

Suggestions:
------------

To cover framebuffers of both 9400M and 9600M GT, I would suggest to
implement a conditional on "gpu-power-prefs".  Depending on the value of
byte 0x3B, the according framebuffer is selected.  However, this requires
kernel access to the EFI variables.

We must tell GCC to use even register for variable passed to ldrd
instruction.  Without this patch GCC 4.2.1 puts this variable to r2/r3 on
EABI and r3/r4 on OABI, so force it to r2/r3.  This does not change
anything when EABI and OABI compilation works OK.

Without this patch and with OABI I get:

Commit 48b32a35 ("reiserfs: use generic
xattr handlers") introduced a problem that causes corruption when extended
attributes are replaced with a smaller value.

The issue is that the reiserfs_setattr to shrink the xattr file was moved
from before the write to after the write.

The root issue has always been in the reiserfs xattr code, but was papered
over by the fact that in the shrink case, the file would just be expanded
again while the xattr was written.

The end result is that the last 8 bytes of xattr data are lost.

This patch fixes it to use new_size.

Commit 677c9b2e ("reiserfs: remove
privroot hiding in lookup") removed the magic from the lookup code to hide
the .reiserfs_priv directory since it was getting loaded at mount-time
instead.  The intent was that the entry would be hidden from the user via
a poisoned d_compare, but this was faulty.

This introduced a security issue where unprivileged users could access and
modify extended attributes or ACLs belonging to other users, including
root.

This patch resolves the issue by properly hiding .reiserfs_priv.  This was
the intent of the xattr poisoning code, but it appears to have never
worked as expected.  This is fixed by using d_revalidate instead of
d_compare.

This patch makes -oexpose_privroot a no-op.  I'm fine leaving it this way.
The effort involved in working out the corner cases wrt permissions and
caching outweigh the benefit of the feature.

My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was
testing a whole set of patches together and missed a conversion to the
new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake

Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or
we'll end up reading the wrong graphics memory, likely causing hangs,
crashes, or worse.

call usb_autopm_get_interface() or usb_autopm_put_interface() for
runtime PM to work.  Runtime PM can be controlled by the driver's
primary interface; the additional interfaces it claims shouldn't
interfere.  As things stand, the claimed interfaces will prevent the
device from autosuspending.

To fix this problem, the patch sets interfaces to the suspended state
when they are claimed.

Also, although in theory this shouldn't matter, the patch changes the
suspend code so that interfaces are suspended in reverse order from
detection and resuming.  This is how the PM core works, and we ought
to use the same approach.

This patch (as1369) fixes a problem in ehci-hcd.  Some controllers
occasionally run into trouble when the driver reclaims siTDs too
quickly.  This can happen while streaming audio; it causes the
controller to crash.

The patch changes siTD reclamation to work the same way as iTD
reclamation: Completed siTDs are stored on a list and not reused until
at least one frame has passed.

This patch (as1363) changes the way USB remote wakeup is handled
during system sleeps.  It won't be enabled unless an interface driver
specifically needs it.  Also, it won't be enabled during the FREEZE or
QUIESCE phases of hibernation, when the system doesn't respond to
wakeup events anyway.  Finally, if the device is already
runtime-suspended with remote wakeup enabled, but wakeup is supposed
to be disabled for the system sleep, the device gets woken up so that
it can be suspended again with the proper wakeup setting.

This will fix problems people have reported with certain USB webcams
that generate wakeup requests when they shouldn't, and as a result
cause system suspends to fail.  See

I read a rumor that the AdLink ND6530 USB RS232, RS422 and RS485
isolated adapter is actually a PL2303 based usb serial adapter. I
tried it out, and as far as I can tell it works.

It appears that the DA8xx/OMAP-L1x glue layer went into the kernel uncompilable:
commit 1960e693 (davinci: da8xx/omapl1: add
support for the second sysconfig module) has renamed DA8XX_SYSCFG_* macros to
DA8XX_SYSCFG0_* and it's been committed before the glue layer...
