31f7c3a688 Device tree core updates for v3.12 
Generally minor changes. A bunch of bug fixes, particularly for
 initialization and some refactoring. Most notable change if feeding the
 entire flattened tree into the random pool at boot. May not be
 significant, but shouldn't hurt either.

 "Generally minor changes.  A bunch of bug fixes, particularly for
  initialization and some refactoring.  Most notable change if feeding
  the entire flattened tree into the random pool at boot.  May not be

Tim Bird questions whether the boot time cost of the random feeding may
be noticeable.  And "add_device_randomness()" is definitely not some
speed deamon of a function.

7426d62871 Add the ability to collect I/O statistics on user-defined regions of a 
device-mapper device.  This dm-stats code required the reintroduction of
 a div64_u64_rem() helper, but as a separate method that doesn't slow
 down div64_u64() -- especially on 32-bit systems.
 
 Allow the error target to replace request-based DM devices
 (e.g. multipath) in addition to bio-based DM devices.

d0d2727710 vfs: make sure we don't have a stale root path if unlazy_walk() fails 
When I moved the RCU walk termination into unlazy_walk(), I didn't copy
quite all of it: for the successful RCU termination we properly add the
necessary reference counts to our temporary copy of the root path, but
for the failure case we need to make sure that any temporary root path
information is cleared out (since it does _not_ have the proper
reference counts from the RCU lookup).

We could clean up this mess by just always dropping the temporary root
information, but Al points out that that would mean that a single lookup
through symlinks could see multiple different root entries if it races
with another thread doing chroot.  Not that I think we should really
care (we had that before too, back before we had a copy of the root path
in the nameidata).

Al says he has a cunning plan.  In the meantime, this is the minimal fix
for the problem, even if it's not all that pretty.

fa91515cbf ARM: Renesas SoC cleanup, refactoring and more SMP support 
Lots of cleanup and refactoring and some SMP additions for Renesas
 platforms.  Due to some inter-dependencies with other arm-soc
 branches, this Renesas stuff was separated out for sending after the
 other branches were merged.
 
 Highlights:
 - remove unused board support and cleanup of unused headers
 - refactoring of init and device registration
 - simplify IRQ initialization
 
 Conflicts: Too many. Most of these are because Simon chose to send
 some board updates through the V4L tree that ends up colliding with
 the main platform changes. We'll work with him on sorting out his
 workflow:
 
 - arch/arm/boot/dts/r8a7740.dtsi:
   - Add/add conflict in a devicetree file (keep both)
 
 - arch/arm/mach-shmobile/Makefile:
   - Splitting out of clock files collides with intc move to DT.
     Keep HEAD version but remove intc-* files for R8A7740 and R8A7779.
 
 - arch/arm/mach-shmobile/board-bockw.c:
   - Keep HEAD but remove i2c, hspi and mmc device init calls
 
 - arch/arm/mach-shmobile/board-marzen.c
   - Remove mach/hardware.h include and r8a7779_add_usb_phy_device() call,
     everything else stays.
 
 - arch/arm/mach-shmobile/include/mach/r8a7778.h:
   - From HEAD, Keep camera-rcar.h include and r8a7778_add_vin_device()
   - From branch, keep everything
 
 - arch/arm/mach-shmobile/include/mach/r8a7779.h:
   - From HEAD, Keep only camera-rcar.h include and r8a7779_add_vin_device()
 
 - arch/arm/mach-shmobile/setup-r8a7778.c
   - Keep HEAD, but drop the MMC section (struct resource + add_mmc_device())
   - take the new function name from our side (r8a7778_add_dt_devices())
 
 - arch/arm/mach-shmobile/setup-r8a7779.c
   - Keep HEAD, but drop r8a7779_add_usb_phy_device()
 
 I've also pushed a test-merge2 branch where you can see how I resolved
 them.

 only thing this cycle are core PM updates and CPUidle support for
 ARM's TC2 big.LITTLE development platform.
 
 Conflicts:
 
 One cleanup/reorg conflict with a new entry in
 drivers/cpuidle/Makefile.  Append the new entry after the existing
 ones.  A follow up patch for v3.12-rc will make the new entry conform
 to the cleanup/reorg.

 helps a small segment of the kernel community.
 
 Oleg Nesterov had a few changes from 3.11, but were mostly clean ups
 and not worth pushing in the -rc time frame.
 
 Li Zefan had small clean up with annotating a raw_init with __init.
 
 I fixed a slight race in updating function callbacks, but the race
 is so small and the bug that happens when it occurs is so minor it's
 not even worth pushing to stable.
 
 The only real enhancement is from Alexander Z Lam that made the
 tracing_cpumask work for trace buffer instances, instead of them all
 sharing a global cpumask.

12d298865e clk: only call get_parent if there is one 
In __clk_init(), after a clock is mostly initialized, a scan is done
of the orphan clocks to see if the clock being registered is the
parent of any of them.

This code assumes that any clock that provides a get_parent method
actually has at least one parent, and that's not a valid assumption.

As a result, an orphan clock with no parent can return *something*
as the parent index, and that value is blindly used to dereference
the orphan's parent_names[] array (which will be ZERO_SIZE_PTR or
NULL).

Fix this by ensuring get_parent is only called for orphans with at
least one parent.

                 |          __getcwd

The big one here is the rename_lock (seqlock) contention in d_path()
and the getcwd system call. This patch will eliminate the need to take
the rename_lock while translating dentries into the full pathnames.

The need to take the rename_lock is to make sure that no rename
operation can be ongoing while the translation is in progress. However,
only one thread can take the rename_lock thus blocking all the other
threads that need it even though the translation process won't make
any change to the dentries.

This patch will replace the writer's write_seqlock/write_sequnlock
sequence of the rename_lock of the callers of the prepend_path() and
__dentry_path() functions with the reader's read_seqbegin/read_seqretry
sequence within these 2 functions. As a result, the code will have to
retry if one or more rename operations had been performed. In addition,
RCU read lock will be taken during the translation process to make sure
that no dentries will go away. To prevent live-lock from happening,
the code will switch back to take the rename_lock if read_seqretry()
fails for three times.

To further reduce spinlock contention, this patch does not take the
dentry's d_lock when copying the filename from the dentries. Instead,
it treats the name pointer and length as unreliable and just copy
the string byte-by-byte over until it hits a null byte or the end of
string as specified by the length. This should avoid stepping into
invalid memory address. The error cases are left to be handled by
the sequence number check.

The following code re-factoring are also made:
1. Move prepend('/') into prepend_name() to remove one conditional
   check.
2. Move the global root check in prepend_path() back to the top of
   the while loop.

With this patch, the _raw_spin_lock will now account for only 1.2%
of the total CPU cycles for the short workload. This patch also has
the effect of reducing the effect of running perf on its profile
since the perf command itself can be a heavy user of the d_path()
function depending on the complexity of the workload.

When taking the perf profile of the high-systime workload, the amount
of spinlock contention contributed by running perf without this patch
was about 16%. With this patch, the spinlock contention caused by
the running of perf will go away and we will have a more accurate
perf profile.

d75671e36e VFIO updates include safer default file flags for VFIO device fds, 
an external user interface exported to allow other modules to hold
 references to VFIO groups, a fix to test for extended config space
 on PCIe and PCI-x, and new hot reset interfaces for PCI devices
 which allows the user to do PCI bus/slot resets when all of the
 devices affected by the reset are owned by the user.
 
 For this last feature, the PCI bus reset interface, I depend on
 changes already merged from Bjorn's PCI pull request.  I therefore
 merged my tree up to commit cb3e433, which I think was the correct
 action, but as Stephen Rothwell noted, I failed to provide a commit
 message indicating why the merge was required.  Sorry for that.
 Thanks,

bf97293eb8 NFS client updates for Linux 3.12 
Highlights include:
 
 - Fix NFSv4 recovery so that it doesn't recover lost locks in cases such as
   lease loss due to a network partition, where doing so may result in data
   corruption. Add a kernel parameter to control choice of legacy behaviour
   or not.
 - Performance improvements when 2 processes are writing to the same file.
 - Flush data to disk when an RPCSEC_GSS session timeout is imminent.
 - Implement NFSv4.1 SP4_MACH_CRED state protection to prevent other
   NFS clients from being able to manipulate our lease and file lockingr
   state.
 - Allow sharing of RPCSEC_GSS caches between different rpc clients
 - Fix the broken NFSv4 security auto-negotiation between client and server
 - Fix rmdir() to wait for outstanding sillyrename unlinks to complete
 - Add a tracepoint framework for debugging NFSv4 state recovery issues.
 - Add tracing to the generic NFS layer.
 - Add tracing for the SUNRPC socket connection state.
 - Clean up the rpc_pipefs mount/umount event management.
 - Merge more patches from Chuck in preparation for NFSv4 migration support.

6c337ad6cc This is possibly the smallest ever set of GFS2 patches for a merge 
window. Also, most of them are bug fixes this time. Two of my
 three patches (moving gfs2_sync_meta and merging the two writepage
 implementations) are clean ups with the third (taking the glock ref
 in examine_bucket) being a fix for a difficult to hit race condition.
 
 The removal of an unused memory barrier is a clean up from Bob Peterson,
 and the "spectator" relates to a rarely used mount option. Ben
 Marzinski's patch fixes a corner case where the incorrect inode
 flags were being set, resulting in incorrect behaviour on fsync.

 "This is possibly the smallest ever set of GFS2 patches for a merge
  window.  Also, most of them are bug fixes this time.

  Two of my three patches (moving gfs2_sync_meta and merging the two

  glock ref in examine_bucket) being a fix for a difficult to hit race
  condition.

  The removal of an unused memory barrier is a clean up from Bob
  Peterson, and the "spectator" relates to a rarely used mount option.
  Ben Marzinski's patch fixes a corner case where the incorrect inode
  flags were being set, resulting in incorrect behaviour on fsync"

ac83871996 autofs4 - fix device ioctl mount lookup 
When reconnecting to automounts at startup an autofs ioctl is used
to find the device and inode of existing mounts so they can be used
to open a file descriptor of possibly covered mounts.

At this time the the caller might not yet "own" the mount so it can
trigger calling ->d_automount(). This causes automount to hang when
trying to reconnect to direct or offset mount types.

Consequently kern_path() can't be used but kern_path_mountpoint() can be.

e5c832d555 vfs: fix dentry RCU to refcounting possibly sleeping dput() 
This is the fix that the last two commits indirectly led up to - making
sure that we don't call dput() in a bad context on the dentries we've
looked up in RCU mode after the sequence count validation fails.

This basically expands d_rcu_to_refcount() into the callers, and then
fixes the callers to delay the dput() in the failure case until _after_
we've dropped all locks and are no longer in an RCU-locked region.

The case of 'complete_walk()' was trivial, since its failure case did
the unlock_rcu_walk() directly after the call to d_rcu_to_refcount(),
and as such that is just a pure expansion of the function with a trivial
movement of the resulting dput() to after 'unlock_rcu_walk()'.

In contrast, the unlazy_walk() case was much more complicated, because
not only does convert two different dentries from RCU to be reference
counted, but it used to not call unlock_rcu_walk() at all, and instead
just returned an error and let the caller clean everything up in
"terminate_walk()".

Happily, one of the dentries in question (called "parent" inside
unlazy_walk()) is the dentry of "nd->path", which terminate_walk() wants
a refcount to anyway for the non-RCU case.

So what the new and improved unlazy_walk() does is to first turn that
dentry into a refcounted one, and once that is set up, the error cases
can continue to use the terminate_walk() helper for cleanup, but for the
non-RCU case.  Which makes it possible to drop out of RCU mode if we
actually hit the sequence number failure case.

0d98439ea3 vfs: use lockred "dead" flag to mark unrecoverably dead dentries 
This simplifies the RCU to refcounting code in particular.

I was originally intending to leave this for later, but walking through
all the dput() logic (see previous commit), I realized that the dput()
"might_sleep()" check was misleadingly weak.  And I removed it as
misleading, both for performance profiling and for debugging.

However, the might_sleep() debugging case is actually true: the final
dput() can indeed sleep, if the inode of the dentry that you are
releasing ends up sleeping at iput time (see dentry_iput()).  So the
problem with the might_sleep() in dput() wasn't that it wasn't true, it
was that it wasn't actually testing and triggering on the interesting
case.

In particular, just about *any* dput() can indeed sleep, if you happen
to race with another thread deleting the file in question, and you then
lose the race to the be the last dput() for that file.  But because it's
a very rare race, the debugging code would never trigger it in practice.

Why is this problematic? The new d_rcu_to_refcount() (see commit
15570086b5: "vfs: reimplement d_rcu_to_refcount() using
lockref_get_or_lock()") does a dput() for the failure case, and it does
it under the RCU lock.  So potentially sleeping really is a bug.

But there's no way I'm going to fix this with the previous complicated
"lockref_get_or_lock()" interface.  And rather than revert to the old
and crufty nested dentry locking code (which did get this right by
delaying the reference count updates until they were verified to be
safe), let's make forward progress.

8aab6a2733 vfs: reorganize dput() memory accesses 
This is me being a bit OCD after all the dentry optimization work this
merge window: profiles end up showing 'dput()' as a rather expensive
operation, and there were two unrelated bad reasons for that.

The first reason was reading d_lockref.count for debugging purposes,
which touches the lockref cacheline (for reads) before really need to.
More importantly, the debugging test in question is _wrong_, and has
hidden bugs.  It's true that we can only sleep when the count goes down
to zero, but the test as-is hides the much more subtle bug that happens
if we race with somebody else deleting the file.

Anyway we _will_ touch that cacheline, but let's do it for a write and
in the right routine (ie in "lockref_put_or_lock()") which annotates the
costs better.  So remove the misleading debug code.

The other was an unnecessary access to the cacheline that contains the
d_lru list, just to check whether we already were on the LRU list or
not.  This is exactly what we have d_flags for, so that we can avoid
touching extra cache lines for the common case.  So just add another bit
for "is this dentry on the LRU".

Finally, mark the tests properly likely/unlikely, so that the common
fast-paths are dense in the instruction stream.

This makes the profiles look much saner.

Merge tag 'mfd-3.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD (multi-function device) updates from Samuel Ortiz:
 "For the 3.12 merge window we have one new driver for the DA9063 PMIC
  from Dialog Semiconductor.

  Besides that driver we also have:

   - Device tree support for the s2mps11 driver

   - More devm_* conversion for the pm8921, max89xx, menelaus, tps65010,
     wl1273 and pcf50633-adc drivers.

   - A conversion to threaded IRQ and IRQ domain for the twl6030 driver.

   - A fairly big update for the rtsx driver: Better power saving
     support, better vendor settings handling, and a few fixes.

   - Support for a couple more boards (COMe-bHL6 and COMe-cTH6) for the
     Kontron driver.

   - A conversion to the dev_get_platdata() API for all MFD drivers.

   - A removal of non-DT (legacy) support for the twl6040 driver.

   - A few fixes and additions (Mic detect level) to the wm5110 register
     tables.

   - Regmap support for the davinci_voicecodec driver.

   - The usual bunch of minor cleanups and janitorial fixes"

4e10f3c988 Kill indirect include of file.h from eventfd.h, use fdget() in cgroup.c 
kernel/cgroup.c is the only place in the tree that relies on eventfd.h
pulling file.h; move that include there.  Switch from eventfd_fget()/fput()
to fdget()/fdput(), while we are at it - eventfd_ctx_fileget() will fail
on non-eventfd descriptors just fine, no need to do that check twice...
