Pull audit updates from Paul Moore:
"The audit changes for v4.11 are relatively small compared to what we
did for v4.10, both in terms of size and impact.
- two patches from Steve tweak the formatting for some of the audit
records to make them more consistent with other audit records.
- three patches from Richard record the name of a module on module
load, fix the logging of sockaddr information when using
socketcall() on 32-bit systems, and add the ability to reset
audit's lost record counter.
- my lone patch just fixes an annoying style nit that I was reminded
about by one of Richard's patches.
All these patches pass our test suite"
* 'stable-4.11' of git://git.infradead.org/users/pcmoore/audit:
audit: remove unnecessary curly braces from switch/case statements
audit: log module name on init_module
audit: log 32-bit socketcalls
audit: add feature audit_lost reset
audit: Make AUDIT_ANOM_ABEND event normalized
audit: Make AUDIT_KERNEL event conform to the specification

Unlike HSW and newer, BYT/CHT devices have no fine control of audio
power domain in i915 side. Since there is little gain by runtime PM
on BYT/CHT, so far, this commit removes the pm_runtime_enable() call
as default.
User who still wants the runtime PM may adjust the corresponding
sysfs files (power/control and power/autosuspend_delay_ms)
appropriately, of course.

The end_device and sas_host devices support BSG ioctls, but the
request_queue allocated for them isn't set up to allocate the struct
scsi_request payload. This leads to memory corruption in the call to
scsi_req_init() in bsg_map_hdr(), since it will memset past the end of
the allocated request. Fix it by setting ->cmd_size on the allocated
request_queue.
Fixes: 82ed4db499b8 ("block: split scsi_request out of struct request")

This patch adds a few lines to the driver to use autosuspend for the

PCIe in AM57x/DRA7x devices is by default configured to work in GEN2 mode.
However there may be situations when working in GEN1 mode is desired. One
example is limitation i925 (PCIe GEN2 mode not supported at junction
temperatures < 0C).
Add support to force Root Complex to work in GEN1 mode if so desired, but
don't force GEN1 mode on any board just yet.

This reverts commit f2593cb1b29185d38db706cbcbe22ed538720ae1.
Paul reported that this patch with older board-2.bin ath10k initialisation
fails on Dell XPS 13:
ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
ath10k/QCA6174/hw3.0/board-2.bin
The reason is that the older board-2.bin does not have the variant version of
the image name and ath10k does not fallback to the older naming scheme.

The release callback may be called from two places - file release
operation and kernfs open file draining. kernfs_open_file->mutex is
used to synchronize the two callsites. This unfortunately leads to
possible circular locking because of->mutex is used to protect the
usual kernfs operations which may use locking constructs which are
held while removing and thus draining kernfs files.
@of->mutex is for synchronizing concurrent kernfs access operations
and all we need here is synchronization between the releaes and drain
paths. As the drain path has to grab kernfs_open_file_mutex anyway,
let's use the mutex to synchronize the release operation instead.

While looking for early possible module loading failures I was
able to reproduce a memory leak possible with kmemleak. There
are a few rare ways to trigger a failure:
o we've run into a failure while processing kernel parameters
(parse_args() returns an error)
o mod_sysfs_setup() fails
o we're a live patch module and copy_module_elf() fails
Chances of running into this issue is really low.

Pull device mapper updates from Mike Snitzer:
- Fix dm-raid transient device failure processing and other smaller
tweaks.
- Add journal support to the DM raid target to close the 'write hole'
on raid 4/5/6.
- Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB.
- Add 'metadata2' feature to dm-cache to separate the dirty bitset out
from other cache metadata. This improves speed of shutting down a
large cache device (which implies writing out dirty bits).
- Fix a memory leak during dm-stats data structure destruction.
- Fix a DM multipath round-robin path selector performance regression
that was caused by less precise balancing across all paths.
- Lastly, introduce a DM core fix for a long-standing DM snapshot
deadlock that is rooted in the complexity of the device stack used in
conjunction with block core maintaining bios on current->bio_list to
manage recursion in generic_make_request(). A more comprehensive fix
to block core (and its hook in the cpu scheduler) would be wonderful
but this DM-specific fix is pragmatic considering how difficult it
has been to make progress on a generic fix.
