718360c59f nfs: fix setting of ACLs on file creation.
nfs3_get_acl() tries to skip posix equivalent ACLs, but misinterprets
the return value of posix_acl_equiv_mode(). Fix it.

This is a regression introduced by
"nfs: use generic posix ACL infrastructure for v3 Posix ACLs"

14864a52cd sound fixes for 3.14-rc1
The big chunks here are the updates for oxygen driver for Xonar DG
 devices, which were slipped from the previous pull request.  They are
 device-specific and thus not too dangerous.
 
 Other than that, all patches are small bug fixes, mainly for Samsung
 build fixes, a few HD-audio enhancements, and other misc ASoC fixes.
 (And this time ASoC merge is less than Octopus, lucky seven :)

DEBUG_FS used to be selected by COMMON_CLK_DEBUG, which was enabled
by tegra_defconfig. However, this config option no longer exists, so
no longer selects DEBUG_FS, and nothing else selects it either. So,
"make tegra_defconfig" no longer enables DEBUG_FS in .config.

Rebuild tegra_defconfig on top of next-20140424, while manually
re-enabling DEBUG_FS.

Reasons for removed entries are:
- I2C_MUX: selected by MEDIA_SUBDRV_AUTOSELECT
- DRM_PANEL: selected by DRM_TEGRA
- NEW_LEDS: selected by many things; at least VT
- LEDS_CLASS: selected by many things; at least VT

d231fab1d0 ARM: multi_v7: copy most options from tegra_defconfig
multi_v7_defconfig was missing a large number of options that were in
tegra_defconfig. This patch adds them. The changes fall into the
following categories:

* Enable more Tegra SoC options/drivers.
* Enable more drivers for Tegra boards.
* Enable more options that are useful for running distros.

The patch removes a few lines as well, simply because those options are
now selected by something else, and "make savedefconfig" removes them. I
verified that the options appear in .config after
"make multi_v7_defconfig".

d22e6338db Fix mountpoint reference leakage in linkat
Recent changes to retry on ESTALE in linkat
(commit 442e31ca5a)
introduced a mountpoint reference leak and a small memory
leak in case a filesystem link operation returns ESTALE
which is pretty normal for distributed filesystems like
lustre, nfs and so on.
Free old_path in such a case.

[AV: there was another missing path_put() nearby - on the previous
goto retry]

d3b7022029 perf buildid-cache: Check relocation when checking for existing kcore
perf buildid-cache does not make another copy of kcore if the buildid
and modules match an existing copy.

That does not take into account the possibility that the kernel has been

too, otherwise do make a copy.

d9b62aba87 perf tools: Adjust kallsyms for relocated kernel
If the kernel is relocated at boot time, kallsyms will not match data
recorded previously.

That does not matter for modules because they are corrected anyway.  It
also does not matter if vmlinux is being used for symbols. But if perf
tools has only kallsyms then the symbols will not match.

Fix by applying the delta gained by comparing the old and current
addresses of the relocation reference symbol.

9176753d1e perf symbols: Fix symbol annotation for relocated kernel
Kernel maps map memory addresses to file offsets.

For symbol annotation, objdump needs the object VMA addresses.  For an
unrelocated kernel, that is the same as the memory address.

The addresses passed to objdump for symbol annotation did not take into
account kernel relocation.

This patch fixes that.

6a02652df5 perf tools: Fix include for non x86 architectures
Commit 71ae8aac ("lib: introduce arch optimized hash library") added an
include to <linux/hash.h> for setting up an architecture specific fast
hash.

Since perf includes directly the non-uapi kernel header, it cannot find
<asm/hash.h> on non-x86 and thus prevents perf to be compiled on every
architecture other than x86.

The problem is the inclusion of <asm/hash.h> in hash.h that results in
the following error originating from util/evlist.c:

  fatal error: asm/hash.h: No such file or directory

This commit simply adds an empty <asm/hash.h> stub/file to fix the
compile issue on non-x86 architectures.

As perf does not use any of these new functions, it fixes the
compilation and therefore seems to be the most appropriate solution to
go with.

Move sync_filesystem() after sb_prepare_remount_readonly().  If writers
sneak in anywhere from sync_filesystem() to sb_prepare_remount_readonly()
it can cause inodes to be dirtied and writeback to occur well after
sys_mount() has completely successfully.

This was spotted by corrupted ubifs filesystems on reboot, but appears
that it can cause issues with any filesystem using writeback.

b890eb4ecc ACPI and power management fixes and cleanups for 3.14-rc1
- ACPI device hotplug fix preventing ACPI drivers from binding to device
    objects that acpi_bus_trim() has been called for and the devices
    represented by them may not be operational.
 
  - Recent cpufreq changes related to the "boost" (turbo) feature broke
    the acpi-cpufreq error code path causing a NULL pointer dereference
    to occur on some systems.  Fix from Konrad Rzeszutek Wilk.
 
  - The log level of a CPU initialization error message added recently
    needs to be reduced, because the particular BIOS issue indicated by
    it turns out to be widespread and doesn't really matter for the
    majority of systems having it.  From Jiang Liu.
 
  - The regulator API needs to be told to stay away from things on systems
    with ACPI BIOSes or it may conflict with the BIOS' own handling of
    voltage regulators.  Fix from Mark Brown that works around a 3.13
    regression in lm90 on PCs occuring if the regulator API is enabled.
 
  - Prevent the Exynos4 devfreq driver from being built on multiplatform,
    because it depends on things that aren't available during such builds.
    From Sachin Kamat.
 
  - Upstream ACPICA doesn't use the bool type as defined in the kernel,
    so modify the kernel's ACPICA code to follow the upstream in that
    respect (only one variable definition is affected) to reduce
    divergences between the two.  From Lv Zheng.
 
  - Make the ACPI device PM code use ACPI_COMPANION() instead of its own
    routine doing the same thing (and invokng ACPI_COMPANION() in the
    process).
 
  - Modify some routines in the ACPI processor driver to follow the
    common convention and return negative integers on errors.  From

Merge tag 'pm+acpi-3.14-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management fixes and cleanups from Rafael Wysocki:

 - ACPI device hotplug fix preventing ACPI drivers from binding to device
   objects that acpi_bus_trim() has been called for and the devices
   represented by them may not be operational.

 - Recent cpufreq changes related to the "boost" (turbo) feature broke
   the acpi-cpufreq error code path causing a NULL pointer dereference
   to occur on some systems.  Fix from Konrad Rzeszutek Wilk.

 - The log level of a CPU initialization error message added recently
   needs to be reduced, because the particular BIOS issue indicated by
   it turns out to be widespread and doesn't really matter for the
   majority of systems having it.  From Jiang Liu.

 - The regulator API needs to be told to stay away from things on systems
   with ACPI BIOSes or it may conflict with the BIOS' own handling of
   voltage regulators.  Fix from Mark Brown that works around a 3.13
   regression in lm90 on PCs occuring if the regulator API is enabled.

 - Prevent the Exynos4 devfreq driver from being built on multiplatform,
   because it depends on things that aren't available during such builds.
   From Sachin Kamat.

 - Upstream ACPICA doesn't use the bool type as defined in the kernel,
   so modify the kernel's ACPICA code to follow the upstream in that
   respect (only one variable definition is affected) to reduce
   divergences between the two.  From Lv Zheng.

 - Make the ACPI device PM code use ACPI_COMPANION() instead of its own
   routine doing the same thing (and invokng ACPI_COMPANION() in the
   process).

 - Modify some routines in the ACPI processor driver to follow the
   common convention and return negative integers on errors.  From
   Hanjun Guo.

0ef38d70d4 alpha: fix broken network checksum
The patch 3ddc5b46a8 breaks networking on
alpha (there is a follow-up fix 5cfe8f1ba5,
but networking is still broken even with the second patch).

The patch 3ddc5b46a8 makes
csum_partial_copy_from_user check the pointer with access_ok. However,
csum_partial_copy_from_user is called also from csum_partial_copy_nocheck
and csum_partial_copy_nocheck is called on kernel pointers and it is
supposed not to check pointer validity.

This bug results in ssh session hangs if the system is loaded and bulk
data are printed to ssh terminal.

This patch fixes csum_partial_copy_nocheck to call set_fs(KERNEL_DS), so
that access_ok in csum_partial_copy_from_user accepts kernel-space
addresses.

75fae117a5 ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled
Commit 384a48d715 "ALSA: hda: HDMI: Support codecs with fewer cvts
than pins" dynamically enabled each pin widget's PIN_OUT only when the
pin was actively in use. This was required on certain NVIDIA CODECs for
correct operation. Specifically, if multiple pin widgets each had their
mux input select the same audio converter widget and each pin widget had
PIN_OUT enabled, then only one of the pin widgets would actually receive
the audio, and often not the one the user wanted!

However, this apparently broke some Intel systems, and commit
6169b67361 "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
CODECs.

This change supports either dynamic or static handling of PIN_OUT,
selected by a flag set up during CODEC initialization. This flag is
enabled for all recent NVIDIA GPUs.

54820f5802 regulator: s2mps11: Fix NULL pointer of_node value when using platform data
When platform_data is used for regulator (of_node of sec-core MFD device
is NULL) the config.of_node for regulator is not initialized. This NULL
value of config.of_node is later stored during regulator_register().
Thus any call by regulator consumers to of_get_regulator() will fail on
of_parse_phandle() returning NULL.

In this case (using platform_data and parent's driver of_node is NULL)
set the config.of_node to reg_node from platform_data.
