In case of error, the function platform_device_register_resndata()
returns ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().

Set feature-libunwind-debug-frame. We don't want it in
CORE_FEATURE_TESTS because it's not the generic case, but we
need to set it in the !feature-libunwind case.
Also, because x86 distributions typically don't have
dwarf_find_debug_frame() unwinding method:
test-libunwind-debug-frame.c:(.text+0x31): undefined reference to `_Ux86_64_dwarf_find_debug_frame'

The recent change in sysfs triggered a kernel WARNING at unloading a
sound driver like
WARNING: CPU: 3 PID: 2247 at fs/sysfs/group.c:214 sysfs_remove_group+0xe8/0xf0()
sysfs group ffffffff81ab7b20 not found for kobject 'event14'
for each jack instance. It's because the unregistration of jack input
device is done in dev_free callback, which is called after
snd_card_disconnect(). Since device_unregister(card->card_dev) is
called in snd_card_disconnect(), the whole sysfs entries belonging to
card->card_dev have been already removed recursively. Thus this
results in a warning as input_unregister_device() yet tries to
unregister the already removed sysfs entry.
For fixing this mess, we need to unregister the jack input device at
dev_disconnect callback so that it's called before unregistering the
card->card_dev.

Unbalanced calls to snd_imx_pcm_trigger() may result in endless
FIQ activity and thus provoke eternal sound. While on the first glance,
the switch statement looks pretty symmetric, the SUSPEND/RESUME
pair is not: the suspend case comes along snd_pcm_suspend_all(),
which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
This way userland may provoke an unbalanced resume, which might cause
the fiq_enable counter to increase and never return to zero again,
so eventually imx_pcm_fiq is never disabled.
Simply removing the fiq_enable will solve the problem, as long as
one never goes play and capture game simultaneously, but beware
trying both at once, the early TRIGGER_STOP will cut off the other
activity prematurely. So now playing and capturing is scrutinized
separately, instead of by counting.

Pull xfs update from Ben Myers:
"For 3.13-rc1 we have an eclectic assortment of bugfixes, cleanups, and
refactoring. Bugfixes that stand out are the fix for the AGF/AGI
deadlock, incore extent list fixes, verifier fixes for v4 superblocks
and growfs, and memory leaks. There are some asserts, warnings, and
strings that were cleaned up. There was further rearrangement of code
to make libxfs and the kernel sync up more easily, differences between
v2 and v3 directory code were abstracted using an ops vector,
xfs_inactive was reworked, and the preallocation/hole punching code
was refactored.
- simplify kmem_zone_zalloc
- add traces for AGF/AGI read ops
- add additional AIL traces
- fix xfs_remove AGF vs AGI deadlock
- fix the extent count of new incore extent page in the indirection
array
- don't fail bad secondary superblocks verification on v4 filesystems
due to unzeroed bits after v4 fields
- fix possible NULL dereference in xlog_verify_iclog
- remove redundant assert in xfs_dir2_leafn_split
- prevent stack overflows from page cache allocation
- fix some sparse warnings
- fix directory block format verifier to check the leaf entry count
- abstract the differences in dir2/dir3 via an ops vector
- continue process of reorganization to make libxfs/kernel code
merges easier
- refactor the preallocation and hole punching code
- fix for growfs and verifiers
- remove unnecessary scary corruption error when probing non-xfs
filesystems
- remove extra newlines from strings passed to printk
- prevent deadlock trying to cover an active log
- rework xfs_inactive()
- add the inode directory type support to XFS_IOC_FSGEOM
- cleanup (remove) usage of is_bad_inode
- fix miscalculation in xfs_iext_realloc_direct which results in
oversized direct extent list
- remove unnecessary count arg to xfs_iomap_write_allocate
- fix memory leak in xlog_recover_add_to_trans
- check superblock instead of block magic to determine if dtype field
is present
- fix lockdep annotation due to project quotas
- fix regression in xfs_node_toosmall which can lead to incorrect
directory btree node collapse
- make log recovery verify filesystem uuid of recovering blocks
- fix XFS_IOC_FREE_EOFBLOCKS definition
- remove invalid assert in xfs_inode_free

This is harmless but cdc_ncm_setup() returns negative error codes
truncated to u8 values. There is only one caller and treats all
non-zero returns as errors but doesn't store the the return code. So
the code works correctly but it's messy and upsets the static checkers.

This first patch adds the ability for us to do a server side copy
(ie fast copy offloaded to the server to perform, aka refcopy)
"cp --reflink"
of one file to another located on the same server. This
is much faster than traditional copy (which requires
reading and writing over the network and extra
memcpys).
This first version is not going to be copy
files larger than about 1MB (to Samba) until I add
support for multiple chunks and for autoconfiguring
the chunksize.
It includes:
1) processing of the ioctl
2) marshalling and sending the SMB2/SMB3 fsctl over the network
3) simple parsing of the response
It does not include yet (these will be in followon patches to come soon):
1) support for multiple chunks
2) support for autoconfiguring and remembering the chunksize
3) Support for the older style copychunk which Samba 4.1 server supports
(because this requires write permission on the target file, which
cp does not give you, apparently per-posix). This may require
a distinct tool (other than cp) and other ioctl to implement.

Pull thermal management updates from Zhang Rui:
"This time we only have a few changes as there are no soc thermal
changes from Eduardo. The only big change is the introduction of
TMON, a tool to help visualize, tune, and test the thermal subsystem.
The rest is mostly cleanups and fixes all over.
Specifics:
- introduce TMON, a tool base on thermal sysfs I/F. It can be used
to visualize, tune and test the thermal subsystem.
- fix a zone/cooling device binding problem, when both thermal zone
bind parameters and .bind() callback are available"
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
tools/thermal: Introduce tmon, a tool for thermal subsystem
thermal: Fix binding problem when there is thermal zone params
thermal: cpu_cooling: fix return value check in cpufreq_cooling_register()
Thermal: Check for validity before doing kfree
thermal/intel_powerclamp: Add newer CPU models
Thermal: Tidy up error handling in powerclamp_init
thermal: Kconfig: cosmetic fixes
ACPI/thermal : Remove zone disabled warning
typo in drivers/thermal/Kconfig: lpatform instead of platform

We care about the upper 32 bits here so we have to use 1ULL instead of 1

Not required anymore as flips are always done on the kernel's channel,
which means we can use a proper software object class instead.

Pull device mapper changes from Mike Snitzer:
"A set of device-mapper changes for 3.13.
Improve reliability of buffer allocations for dm messages with a small
number of arguments, a couple path group initialization fixes for dm
multipath, a fix for resizing a dm array, various fixes and
optimizations for dm cache, a fix for device mapper's Kconfig menu
indentation.
Features added include:
- dm crypt support for activating legacy CBC TrueCrypt containers
(useful for forensics of these old TCRYPT containers)
- reduced dm-cache memory requirements for each block in the cache
- basic support for shrinking a dm-cache's cache (fast) device
- most notably, dm-cache support for managing cache coherency when
deploying dm-cache with sophisticated origin volumes (that support
hardware snapshots and/or clustering): these changes come in the
form of a new passthrough operation mode and a cache block
invalidation interface"
