Pull vfs dentry reference count fix from Al Viro.
This fixes a possible inode_permission NULL pointer dereference (and
other problems) that were due to the root dentry count being decremented
too much. In commit 48a066e72d ("RCU'd vfsmounts") the placement of
clearing the LOOKUP_RCU bit changed, and we then returned failure of
incrementing the lockref on the parent dentry with LOOKUP_RCU cleared.
But that meant we needed to go through the same cleanup routines that
the later failures did wrt LOOKUP_ROOT and nd->root.

Failure to grab reference to parent dentry should go through the

caller thinking it needs to path_put() nd->root, with obvious
nasty results once we'd hit that bug enough times to drive the
refcount of root dentry all the way to zero...

The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself. But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls. This is a regression
compared with the previous static quirks.
This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.

"The main thing that caused problem was that CONFIG_CPU_LITTLE_ENDIAN
got turned on with allyesconfig and such, which is not a very good

commit 566c09c534 raid5: relieve lock contention in get_active_stripe()
modified the locking in get_active_stripe() reducing the range
protected by the (highly contended) device_lock.
Unfortunately it reduced the range too much opening up some races.
One race can occur if get_priority_stripe runs between the
test on sh->count and device_lock being taken.
This will mean that sh->lru is not empty while get_active_stripe
thinks ->count is zero resulting in a 'BUG' firing.
Another race happens if __release_stripe is called immediately
after sh->count is tested and found to be non-zero. If STRIPE_HANDLE
is not set, get_active_stripe should increment ->active_stripes
when it increments ->count from 0, but as it didn't think it was 0,
it doesn't.
Extending device_lock to cover the test on sh->count close these
races.
While we are here, fix the two BUG tests:
-If count is zero, then lru really must not be empty, or we've
lock the stripe_head somehow - no other tests are relevant.
-STRIPE_ON_RELEASE_LIST is completely independent of ->lru so
testing it is pointless.

If a cgroup file implements either read_map() or read_seq_string(),
such file is served using seq_file by overriding file->f_op to
cgroup_seqfile_operations, which also overrides the release method to
single_release() from cgroup_file_release().
Because cgroup_file_open() didn't use to acquire any resources, this
used to be fine, but since f7d58818ba ("cgroup: pin
cgroup_subsys_state when opening a cgroupfs file"), cgroup_file_open()
pins the css (cgroup_subsys_state) which is put by
cgroup_file_release(). The patch forgot to update the release path
for seq_files and each open/release cycle leaks a css reference.
Fix it by updating cgroup_file_release() to also handle seq_files and
using it for seq_file release path too.

The source of this problem is that SCSI hosts are removed from
ATA ports after calling ata_tport_delete() which removes the
port's sysfs directory, among other things. Now, after commit
bcdde7e221, the sysfs directory is removed along with all of
its subdirectories that include the SCSI host's sysfs directory
and its subdirectories at this point. Consequently, when
device_del() is finally called for any child device of the SCSI
host and tries to remove its "power" group (which is already
gone then), it triggers the above warning.
To make the warnings go away, change the removal ordering in
ata_port_detach() so that the SCSI host is removed from the
port before ata_tport_delete() is called.

This is an actual deadlock because an interrupt doing an allocation will

forever waiting for the write side to complete.

When a headphone jack is configurable as input, the generic parser
tries to make it retaskable as Headphone Mic. The switching can be
done smoothly if Capture Source control exists (i.e. there is another
input source). Or when user explicitly enables the creation of jack
mode controls, "Headhpone Mic Jack Mode" will be created accordingly.
However, if the headphone mic is the only input source, we have to
create "Headphone Mic Jack Mode" control because there is no capture
source selection. Otherwise, the generic parser assumes that the
input is constantly enabled, thus the headphone is permanently set
as input. This situation happens on the old MacBook Airs where no
input is supported properly, for example.
This patch fixes the problem: now "Headphone Mic Jack Mode" is created
when such an input selection isn't possible.

The PL061 driver had the irqdomain initialization in an unfortunate
place: when used with device tree (and thus passing the base IRQ
0) the driver would work, as this registers an irqdomain and waits
for mappings to be done dynamically as the devices request their
IRQs, whereas when booting using platform data the irqdomain core
would attempt to allocate IRQ descriptors dynamically (which works
fine) but also to associate the irq_domain_associate_many() on all
IRQs, which in turn will call the mapping function which at this
point will try to set the type of the IRQ and then tries to acquire
a non-initialized spinlock yielding a backtrace like this:

This moves the irqdomain initialization to a point where the spinlock
and GPIO chip are both fully propulated, so the callbacks can be used
without crashes.
I had some problem reproducing the crash, as the devm_kzalloc():ed
zeroed memory would seemingly mask the spinlock as something OK,
but by poisoning the lock like this:
u32 *dum;
dum = (u32 *) &chip->lock;
*dum = 0xaaaaaaaaU;
I could reproduce, fix and test the patch.

1) is a bug fix that happens when root does the following:
echo function_graph > current_tracer
modprobe foo
echo nop > current_tracer
This causes the ftrace internal accounting to get screwed up and
crashes ftrace, preventing the user from using the function tracer
after that.
2) if a TRACE_EVENT has a string field, and NULL is given for it.
The internal trace event code does a strlen() and strcpy() on the
source of field. If it is NULL it causes the system to oops.
This bug has been there since 2.6.31, but no TRACE_EVENT ever passed
in a NULL to the string field, until now.

Pull tracing fixes from Steven Rostedt:
"This includes two fixes.
1) is a bug fix that happens when root does the following:
echo function_graph > current_tracer
modprobe foo
echo nop > current_tracer
This causes the ftrace internal accounting to get screwed up and
crashes ftrace, preventing the user from using the function tracer
after that.
2) if a TRACE_EVENT has a string field, and NULL is given for it.
The internal trace event code does a strlen() and strcpy() on the
source of field. If it is NULL it causes the system to oops.
This bug has been there since 2.6.31, but no TRACE_EVENT ever passed
in a NULL to the string field, until now"
* tag 'trace-fixes-v3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
ftrace: Fix function graph with loading of modules
tracing: Allow events to have NULL strings
Pull ceph bug-fixes from Sage Weil:
"These include a couple fixes to the new fscache code that went in
during the last cycle (which will need to go stable@ shortly as well),
a couple client-side directory fragmentation fixes, a fix for a race
in the cap release queuing path, and a couple race fixes in the
request abort and resend code.
Obviously some of this could have gone into 3.12 final, but I
preferred to overtest rather than send things in for a late -rc, and
then my travel schedule intervened"
* 'for-linus-bugs' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
ceph: allocate non-zero page to fscache in readpage()
ceph: wake up 'safe' waiters when unregistering request
ceph: cleanup aborted requests when re-sending requests.
ceph: handle race between cap reconnect and cap release
ceph: set caps count after composing cap reconnect message
ceph: queue cap release in __ceph_remove_cap()
ceph: handle frag mismatch between readdir request and reply
ceph: remove outdated frag information
ceph: hung on ceph fscache invalidate in some cases
We are missing building windfarm_max6690_sensor.o when building
CONFIG_WINDFARM_RM31. Usually all the windfarm drivers are built
and thus this isn't a problem but some more "tailored" setups
(Gentoo ?) building only that driver are not working because
the require sensor module is missing.

* acpica:
ACPI: Clean up incorrect inclusions of ACPICA headers
ACPICA: Update version to 20131115.
ACPICA: Add support to delete all objects attached to the root namespace node.
ACPICA: Delete all attached data objects during namespace node deletion.
ACPICA: Resources: Fix loop termination for the get AML length function.
ACPICA: Tests: Add CHECKSUM_ABORT protection for test utilities.
ACPICA: Debug output: Do not emit function nesting level for kernel build.
Mostly bugfixes and a few small code removals. Worth pointing out is:
- A handful of more fixes to get DT enablement working properly on OMAP,
finding new breakage of things that don't work quite right yet without
the traditional board files. I expect a bit more of this to come in this
release as people test on their hardware.
- Implementation of power_down_finish() on vexpress, to make kexec work and
to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
- A handful of minor fixes for various platforms.
