Linus Torvalds 3f0c3c8fe3 Merge git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes
Pull GFS2 fixes from Steven Whitehouse:
 "Here are three GFS2 fixes for the current kernel tree.  These are all
  related to the block reservation code which was added at the merge
  window.  That code will be getting an update at the forthcoming merge
  window too.  In the mean time though there are a few smaller issues
  which should be fixed.

  The first patch resolves an issue with write sizes of greater than 32
  bits with the size hinting code.  The second ensures that the
  allocation data structure is initialised when using xattrs and the
  third takes into account allocations which may have been made by other
  nodes which affect a reservation on the local node."

* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes:
  GFS2: Take account of blockages when using reserved blocks
  GFS2: Fix missing allocation data for set/remove xattr
  GFS2: Make write size hinting code common

Linus Torvalds 1547cb80db - Fixes a regression, introduced in 3.6-rc1, when a file is closed before its
shared memory mapping is dirtied and unmapped. The lower file was being
   released when the eCryptfs file was closed and the dirtied pages could not be
   written out.
 - Adds a call to the lower filesystem's ->flush() from ecryptfs_flush().
 - Fixes a regression, introduced in 2.6.39, when a file is renamed on top of
   another file. The target file's inode was not being evicted and the space
   taken by the file was not reclaimed until eCryptfs was unmounted.

Linus Torvalds dd383af6aa Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
 "I realise this a bit bigger than I would want at this point.

  Exynos is a large chunk, I got them to half what they wanted already,
  and hey its ARM based, so not going to hurt many people.

  Radeon has only two fixes, but the PLL fixes were a bit bigger, but
  required for a lot of scenarios, the fence fix is really urgent.

  vmwgfx: I've pulled in a dumb ioctl support patch that I was going to
  shove in later and cc stable, but we need it asap, its mainly to stop
  mesa growing a really ugly dependency in userspace to run stuff on
  vmware, and if I don't stick it in the kernel now, everyone will have
  to ship ugly userspace libs to workaround it.

  nouveau: single urgent fix found in F18 testing, causes X to not start
  properly when f18 plymouth is used

  i915: smattering of fixes and debug quieting

  gma500: single regression fix

  So as I said a bit large, but its fairly well scattered and its all
  stuff I'll be shipping in F18's 3.6 kernel."

Linus Torvalds 55815f7014 vfs: make O_PATH file descriptors usable for 'fstat()'
We already use them for openat() and friends, but fstat() also wants to
be able to use O_PATH file descriptors.  This should make it more
directly comparable to the O_SEARCH of Solaris.

Note that you could already do the same thing with "fstatat()" and an
empty path, but just doing "fstat()" directly is simpler and faster, so
there is no reason not to just allow it directly.

See also commit 332a2e1244, which did the same thing for fchdir, for
the same reasons.

Aaron Lu f25b70613c ACPI / PM: Use KERN_DEBUG when no power resources are found
commit a606dac368 adds support to link
devices which have _PRx, if a device does not have _PRx, a warning
message will be printed.

This commit is for ZPODD on Intel ZPODD capable platforms, on other
platforms, it has no problem if there is no power resource for this
device, so a warning here is not appropriate, change it to debug.

Tyler Hicks 8335eafc28 eCryptfs: Copy up attributes of the lower target inode after rename
After calling into the lower filesystem to do a rename, the lower target
inode's attributes were not copied up to the eCryptfs target inode. This
resulted in the eCryptfs target inode staying around, rather than being
evicted, because i_nlink was not updated for the eCryptfs inode. This
also meant that eCryptfs didn't do the final iput() on the lower target
inode so it stayed around, as well. This would result in a failure to
free up space occupied by the target file in the rename() operation.
Both target inodes would eventually be evicted when the eCryptfs
filesystem was unmounted.

This patch calls fsstack_copy_attr_all() after the lower filesystem
does its ->rename() so that important inode attributes, such as i_nlink,
are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called
and eCryptfs can drop its final reference on the lower inode.

Tyler Hicks 64e6651dcc eCryptfs: Call lower ->flush() from ecryptfs_flush()
Since eCryptfs only calls fput() on the lower file in
ecryptfs_release(), eCryptfs should call the lower filesystem's
->flush() from ecryptfs_flush().

If the lower filesystem implements ->flush(), then eCryptfs should try
to flush out any dirty pages prior to calling the lower ->flush(). If
the lower filesystem does not implement ->flush(), then eCryptfs has no
need to do anything in ecryptfs_flush() since dirty pages are now
written out to the lower filesystem in ecryptfs_release().

Tyler Hicks 7149f2558d eCryptfs: Write out all dirty pages just before releasing the lower file
Fixes a regression caused by:

821f749 eCryptfs: Revert to a writethrough cache model

That patch reverted some code (specifically, 32001d6f) that was
necessary to properly handle open() -> mmap() -> close() -> dirty pages
-> munmap(), because the lower file could be closed before the dirty
pages are written out.

Rather than reapplying 32001d6f, this approach is a better way of
ensuring that the lower file is still open in order to handle writing
out the dirty pages. It is called from ecryptfs_release(), while we have
a lock on the lower file pointer, just before the lower file gets the
final fput() and we overwrite the pointer.

Yishai Hadas dd03e73481 mlx4_core: Fix integer overflows so 8TBs of memory registration works
This patch adds on the fixes done in commits 89dd86db78 ("mlx4_core:
Allow large mlx4_buddy bitmaps") and 3de819e6b6 ("mlx4_core: Fix
integer overflow issues around MTT table") so that memory registration
of up to 8TB (log_num_mtt=31) finally works.

It fixes integer overflows in a few mlx4_table_yyy routines in icm.c
by using a u64 intermediate variable, and int/uint issues that caused
table indexes to become nagive by setting some variables to be u32
instead of int.  These problems cause crashes when a user attempted to
register > 512GB of RAM.

Lin Ming 40bf66ec97 ACPI / PM: Fix resource_lock dead lock in acpi_power_on_device
Commit 0090def("ACPI: Add interface to register/unregister device
to/from power resources") used resource_lock to protect the devices list
that relies on power resource. It caused a mutex dead lock, as below

    acpi_power_on ---> lock resource_lock
      __acpi_power_on
        acpi_power_on_device
          acpi_power_get_inferred_state
            acpi_power_get_list_state ---> lock resource_lock

This patch adds a new mutex "devices_lock" to protect the devices list
and calls acpi_power_on_device in acpi_power_on, instead of
__acpi_power_on, after the resource_lock is released.

Rafael J. Wysocki 8f7412a792 ACPI / PM: Infer parent power state from child if unknown, v2
It turns out that there are ACPI BIOSes defining device objects with
_PSx and without either _PSC or _PRx.  For devices corresponding to
those ACPI objetcs __acpi_bus_get_power() returns ACPI_STATE_UNKNOWN
and their initial power states are regarded as unknown as a result.
If such a device is a parent of another power-manageable device, the
child cannot be put into a low-power state through ACPI, because
__acpi_bus_set_power() refuses to change power states of devices
whose parents' power states are unknown.

To work around this problem, observe that the ACPI power state of
a device cannot be higher-power (lower-number) than the power state
of its parent.  Thus, if the device's _PSC method or the
configuration of its power resources indicates that the device is
in D0, the device's parent has to be in D0 as well.  Consequently,
if the parent's power state is unknown when we've just learned that
its child's power state is D0, we can safely set the parent's
power.state field to ACPI_STATE_D0.

Only increase the higher 32bits if we really detect a wrap around.

v2: instead of increasing the higher 32bits just use the higher
    32bits from the last emitted fence.
v3: also use last emitted fence value as upper limit.

The intention of this patch is to make fences as robust as
they where before introducing 64bit fences. This is
necessary because on older systems it looks like the fence
value gets corrupted on initialization.
