e324f7c9ce ARM: keystone: config: fix build warning when CONFIG_DMADEVICES is not set
Drop automatic selection of TI_EDMA from Keystone Kconfig file,
as it produces build warning in case if CONFIG_DMADEVICES is not set:

warning: (ARCH_KEYSTONE) selects TI_EDMA which has unmet direct dependencies (DMADEVICES && (ARCH_DAVINCI || ARCH_OMAP || ARCH_KEYSTONE))

Instead enable TI EDMA support from defconfig.

db079b1811 ARM: tegra: rebuild tegra_defconfig to add DEBUG_FS
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
- LEDS_TRIGGERS: selected by many things; at least VT
- COMMON_CLK_DEBUG: no longer exists

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".

and with the removal of can_set_xattr we've now allow operations that
wouldn't otherwise be allowed.

With this we can also centralize the special-casing of the osx.

807612db2f fs/super.c: sync ro remount after blocking writers
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.

- 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.

a9a315d414 cifs: Fix check for regular file in couldbe_mf_symlink()
MF Symlinks are regular files containing content in a specified format.

The function couldbe_mf_symlink() checks the mode for a set S_IFREG bit
as a test to confirm that it is a regular file. This bit is also set for
other filetypes and simply checking for this bit being set may return
false positives.

We ensure that we are actually checking for a regular file by using the
S_ISREG macro to test instead.

bc1b0df59e drivers: xen: deaggressive selfballoon driver
Current xen-selfballoon driver is too aggressive which may cause OOM be
triggered more often. Eg. this bug reported by James:
https://lkml.org/lkml/2013/11/21/158

There are two mainly reasons:
1) The original goal_page didn't consider some pages used by kernel space, like
slab pages and pages used by device drivers.

2) The balloon driver may not give back memory to guest OS fast enough when the
workload suddenly aquries a lot of physical memory.

In both cases, the guest OS will suffer from memory pressure and OOM may
be triggered.

The fix is make xen-selfballoon driver not that aggressive by adding extra 10%
of total ram pages to goal_page.
It's more valuable to keep the guest system reliable and response faster than
balloon out these 10% pages to XEN.

08ece5bb23 xen/grant-table: Avoid m2p_override during mapping
The grant mapping API does m2p_override unnecessarily: only gntdev needs it,
for blkback and future netback patches it just cause a lock contention, as
those pages never go to userspace. Therefore this series does the following:
- the original functions were renamed to __gnttab_[un]map_refs, with a new
  parameter m2p_override
- based on m2p_override either they follow the original behaviour, or just set
  the private flag and call set_phys_to_machine
- gnttab_[un]map_refs are now a wrapper to call __gnttab_[un]map_refs with
  m2p_override false
- a new function gnttab_[un]map_refs_userspace provides the old behaviour

It also removes a stray space from page.h and change ret to 0 if
XENFEAT_auto_translated_physmap, as that is the only possible return value
there.

v2:
- move the storing of the old mfn in page->index to gnttab_map_refs
- move the function header update to a separate patch

v3:
- a new approach to retain old behaviour where it needed
- squash the patches into one

v4:
- move out the common bits from m2p* functions, and pass pfn/mfn as parameter
- clear page->private before doing anything with the page, so m2p_find_override
  won't race with this

v5:
- change return value handling in __gnttab_[un]map_refs
- remove a stray space in page.h
- add detail why ret = 0 now at some places

v6:
- don't pass pfn to m2p* functions, just get it locally

The slub code does some setup during early boot in
early_kmem_cache_node_alloc() with some local data.  There is no
possible way that another CPU can see this data, so the slub code
doesn't unnecessarily lock it.  However, some new lockdep asserts
check to make sure that add_partial() _always_ has the list_lock
held.

Just add the locking, even though it is technically unnecessary.

433a91ff5f mm: sl[uo]b: fix misleading comments
On x86, SLUB creates and handles <=8192-byte allocations internally.
It passes larger ones up to the allocator.  Saying "up to order 2" is,
at best, ambiguous.  Is that order-1?  Or (order-2 bytes)?  Make
it more clear.

SLOB commits a similar sin.  It *handles* page-size requests, but the
comment says that it passes up "all page size and larger requests".

SLOB also swaps around the order of the very-similarly-named
KMALLOC_SHIFT_HIGH and KMALLOC_SHIFT_MAX #defines.  Make it
consistent with the order of the other two allocators.

c2c93e5b7f arm64: mm: Introduce PTE_WRITE
We have the following means for encoding writable or dirty ptes:

                                PTE_DIRTY       PTE_RDONLY
!pte_dirty && !pte_write        0               1
!pte_dirty && pte_write         0               1
pte_dirty && !pte_write         1               1
pte_dirty && pte_write          1               0

So we can't distinguish between writable clean ptes and read only
ptes. This can cause problems with ptes being incorrectly flagged as
read only when they are writable but not dirty.

This patch introduces a new software bit PTE_WRITE which allows us to
correctly identify writable ptes. PTE_RDONLY is now only clear for
valid ptes where a page is both writable and dirty.

7585823619 ceph: simplify ceph_{get,init}_acl
- ->get_acl only gets called after we checked for a cached ACL, so no
   need to call get_cached_acl again.
 - no need to check IS_POSIXACL in ->get_acl, without that it should
   never get set as all the callers that set it already have the check.
 - you should be able to use the full posix_acl_create in CEPH

2def2ef2ae x86, x32: Correct invalid use of user timespec in the kernel
The x32 case for the recvmsg() timout handling is broken:

  asmlinkage long compat_sys_recvmmsg(int fd, struct compat_mmsghdr __user *mmsg,
                                      unsigned int vlen, unsigned int flags,
                                      struct compat_timespec __user *timeout)
  {
          int datagrams;
          struct timespec ktspec;

          if (flags & MSG_CMSG_COMPAT)
                  return -EINVAL;

          if (COMPAT_USE_64BIT_TIME)
                  return __sys_recvmmsg(fd, (struct mmsghdr __user *)mmsg, vlen,
                                        flags | MSG_CMSG_COMPAT,
                                        (struct timespec *) timeout);
          ...

The timeout pointer parameter is provided by userland (hence the __user
annotation) but for x32 syscalls it's simply cast to a kernel pointer
and is passed to __sys_recvmmsg which will eventually directly
dereference it for both reading and writing.  Other callers to
__sys_recvmmsg properly copy from userland to the kernel first.

The bug was introduced by commit ee4fa23c4b ("compat: Use
COMPAT_USE_64BIT_TIME in net/compat.c") and should affect all kernels
since 3.4 (and perhaps vendor kernels if they backported x32 support
along with this code).

Note that CONFIG_X86_X32_ABI gets enabled at build time and only if
CONFIG_X86_X32 is enabled and ld can build x32 executables.

Other uses of COMPAT_USE_64BIT_TIME seem fine.

This addresses CVE-2014-0038.

Pull x86 build bits from Peter Anvin:
 "Various build-related minor bits.

  Most of this is work by David Woodhouse to be able to compile the
  early boot code with clang/llvm; we have also managed to push an
  actual -m16 option into gcc 4.9 so this makes us use that option if
  available instead of hacking it.

  The balance is a patch from Michael Davidson to the relocs program to
  help manual debugging.

  None of these should change the actual compiled binary with currently
  released compilers"
