Pull thermal management fixes from Zhang Rui:
 "Specifics:

   - Fix a problem that Intel SoC DTS thermal driver does not work when

   - Fix a NULL pointer dereference when processor_thermal_device driver
     is loaded on a platform without ACPI support"

  ACPI/int340x_thermal: enumerate INT340X devices even if they're not in _ART/_TRT

Using the native code here can't work properly, as the hypervisor would
normally have cleared the two reason bits by the time Dom0 gets to see
the NMI (if passed to it at all). There's a shared info field for this,
and there's an existing hook to use - just fit the two together. This
is particularly relevant so that NMIs intended to be handled by APEI /
GHES actually make it to the respective handler.

Note that the hook can (and should) be used irrespective of whether
being in Dom0, as accessing port 0x61 in a DomU would be even worse,
while the shared info field would just hold zero all the time. Note
further that hardware NMI handling for PVH doesn't currently work
anyway due to missing code in the hypervisor (but it is expected to
work the native rather than the PV way).

When batching up address ranges for TLB invalidation, we check tlb->end
!= 0 to indicate that some pages have actually been unmapped.

As of commit f045bbb9 ("mmu_gather: fix over-eager
tlb_flush_mmu_free() calling"), we use the same check for freeing these
pages in order to avoid a performance regression where we call
free_pages_and_swap_cache even when no pages are actually queued up.

Unfortunately, the range could have been reset (tlb->end = 0) by
tlb_end_vma, which has been shown to cause memory leaks on arm64.
Furthermore, investigation into these leaks revealed that the fullmm
case on task exit no longer invalidates the TLB, by virtue of tlb->end
 == 0 (in 3.18, need_flush would have been set).

This patch resolves the problem by reverting commit f045bbb9, using
instead tlb->local.nr as the predicate for page freeing in
tlb_flush_mmu_free and ensuring that tlb->end is initialised to a
non-zero value in the fullmm case.

Sleep in atomic context happened on Trats2 board after inserting or
removing SD card because mmc_gpio_get_cd() was called under spin lock.

Fix this by moving card detection earlier, before acquiring spin lock.
The mmc_gpio_get_cd() call does not have to be protected by spin lock
because it does not access any sdhci internal data.
The sdhci_do_get_cd() call access host flags (SDHCI_DEVICE_DEAD). After
moving it out side of spin lock it could theoretically race with driver
removal but still there is no actual protection against manual card
eject.

In commit 5491ce3f ("mmc: sdhci-pxav3: add support for the Armada
38x SDHCI controller"), the sdhci-pxav3 driver was extended to include
support for the SDHCI controller found in the Armada 38x
processor. This mainly involved adding some MBus window related
configuration.

However, this configuration is currently done too early in ->probe():
it is done before clocks are enabled, while this configuration
involves touching the registers of the controller, which will hang the
SoC if the clock is disabled. It wasn't noticed until now because the
bootloader typically leaves gatable clocks enabled, but in situations
where we have a deferred probe (due to a CD GPIO that cannot be taken,
for example), then the probe will be re-tried later, after a clock
disable has been done in the exit path of the failed probe attempt of
the device. This second probe() will hang the system due to the clock
being disabled.

This can for example be produced on Armada 385 GP, which has a CD GPIO
connected to an I2C PCA9555. If the driver for the PCA9555 is not
compiled into the kernel, then we will have the following sequence of
events:

  1. The SDHCI probes
  2. It does the MBus configuration (which works, because the clock is
     left enabled by the bootloader)
  3. It enables the clock
  4. It tries to get the CD GPIO, which fails due to the driver being
     missing, so -EPROBE_DEFER is returned.
  5. Before returning -EPROBE_DEFER, the driver cleans up what was
     done, which includes disabling the clock.
  6. Later on, the SDHCI probe is tried again.
  7. It does the MBus configuration, which hangs because the clock is
     no longer enabled.

This commit does the obvious fix of doing the MBus configuration after
the clock has been enabled by the driver.

Re-tuning for HS400 mode must be done in HS200
mode. Currently there is no support for that.
That needs to be reflected in the code.
Specifically, if tuning is executed in HS400 mode
then return an error, and do not start the
tuning timer if HS200 tuning is being done prior
to switching to HS400.

Note that periodic re-tuning is not expected
to be needed for HS400 but re-tuning is still
needed after the host controller has lost power.
In the case of suspend/resume that is not necessary
because the card is fully re-initialised. That
just leaves runtime suspend/resume with no support
for HS400 re-tuning.

Re-tuning requires that the maximum data length
is limited to 4MiB. The code currently changes
max_blk_count in an attempt to achieve that.
This is wrong because max_blk_count is a different
limit, but it is also un-necessary because
max_req_size is 512KiB anyway. Consequently, the
changes to max_blk_count are removed and the
comment for max_req_size adjusted accordingly.
The comment is also tweaked to show that the 512KiB
limit is a SDMA limit not an ADMA limit.

Fix for BUG_ON(anon_vma->degree) splashes in unlink_anon_vmas() ("kernel
BUG at mm/rmap.c:399!") caused by commit 7a3ef208 ("mm: prevent
endless growth of anon_vma hierarchy")

Anon_vma_clone() is usually called for a copy of source vma in
destination argument.  If source vma has anon_vma it should be already
in dst->anon_vma.  NULL in dst->anon_vma is used as a sign that it's
called from anon_vma_fork().  In this case anon_vma_clone() finds
anon_vma for reusing.

Vma_adjust() calls it differently and this breaks anon_vma reusing
logic: anon_vma_clone() links vma to old anon_vma and updates degree
counters but vma_adjust() overrides vma->anon_vma right after that.  As
a result final unlink_anon_vmas() decrements degree for wrong anon_vma.

This patch assigns ->anon_vma before calling anon_vma_clone().

Commit fee7e49d ("mm: propagate error from stack expansion even for
guard page") made sure that we return the error properly for stack
growth conditions.  It also theorized that counting the guard page
towards the stack limit might break something, but also said "Let's see
if anybody notices".

Somebody did notice.  Apparently android-x86 sets the stack limit very
close to the limit indeed, and including the guard page in the rlimit
check causes the android 'zygote' process problems.

So this adds the (fairly trivial) code to make the stack rlimit check be
against the actual real stack size, rather than the size of the vma that
includes the guard page.

Pull arm64 fixes from Will Deacon:
 "Here is a handful of minor arm64 fixes discovered and fixed over the
  Christmas break.  The main part is adding some missing #includes that
  we seem to be getting transitively but have started causing problems
  in -next.

   - Fix early mapping fixmap corruption by EFI runtime services
   - Fix __NR_compat_syscalls off-by-one
   - Add missing sanity checks for some 32-bit registers
   - Add some missing #includes which we get transitively
   - Remove unused prepare_to_copy() macro"

Pull kgdb/kdb fixes from Jason Wessel:
 "These have been around since 3.17 and in kgdb-next for the last 9
  weeks and some will go back to -stable.

  Summary of changes:

  Cleanups
   - kdb: Remove unused command flags, repeat flags and KDB_REPEAT_NONE

  Fixes
   - kgdb/kdb: Allow access on a single core, if a CPU round up is
     deemed impossible, which will allow inspection of the now "trashed"
     kernel
   - kdb: Add enable mask for the command groups
   - kdb: access controls to restrict sensitive commands"

* tag 'for_linus-3.19-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/kgdb:

  kdb: Add enable mask for groups of commands
  kdb: Categorize kdb commands (similar to SysRq categorization)
  kdb: Remove KDB_REPEAT_NONE flag
  kdb: Use KDB_REPEAT_* values as flags
  kdb: Rename kdb_register_repeat() to kdb_register_flags()

Pull two nfsd bugfixes from Bruce Fields.

* 'for-3.19' of git://linux-nfs.org/~bfields/linux:

Pull two Ceph fixes from Sage Weil:
 "These are both pretty trivial: a sparse warning fix and size_t printk
  thing"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  libceph: fix sparse endianness warnings
  ceph: use %zu for len in ceph_fill_inline_data()

Pull btrfs fixes from Chris Mason:
 "None of these are huge, but my commit does fix a regression from 3.18
  that could cause lost files during log replay.

  This also adds Dave Sterba to the list of Btrfs maintainers.  It
  doesn't mean we're doing things differently, but Dave has really been
  helping with the maintainer workload for years"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
  Btrfs: don't delay inode ref updates during log replay
  Btrfs: correctly get tree level in tree_backref_for_extent
  Btrfs: call inode_dec_link_count() on mkdir error path
  Btrfs: abort transaction if we don't find the block group
  Btrfs, scrub: uninitialized variable in scrub_extent_for_parity()
  Btrfs: add more maintainers

Everything else starts with ICF so the last two should as well.

Fix places they are used to match.
