Pull vfs updates from Al Viro:
"Assorted cleanups and fixes.
Probably the most interesting part long-term is ->d_init() - that will
have a bunch of followups in (at least) ceph and lustre, but we'll
need to sort the barrier-related rules before it can get used for
really non-trivial stuff.
Another fun thing is the merge of ->d_iput() callers (dentry_iput()
and dentry_unlink_inode()) and a bunch of ->d_compare() ones (all
except the one in __d_lookup_lru())"
* 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (26 commits)
fs/dcache.c: avoid soft-lockup in dput()
vfs: new d_init method
vfs: Update lookup_dcache() comment
bdev: get rid of ->bd_inodes

new helper: d_same_name()

vfs: clean up documentation

...
Some of our "for_each_xyz()" macro constructs make gcc unhappy about
lack of braces around if-statements inside or outside the loop, because
the loop construct itself has a "if-then-else" statement inside of it.
The resulting warnings look something like this:
drivers/gpu/drm/i915/i915_debugfs.c: In function ‘i915_dump_lrc’:
drivers/gpu/drm/i915/i915_debugfs.c:2103:6: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses]
if (ctx != dev_priv->kernel_context)
^
even if the code itself is fine.
Since the warning is fairly easy to avoid by adding a braces around the
if-statement near the for_each_xyz() construct, do so, rather than
disabling the otherwise potentially useful warning.
(The if-then-else statements used in the "for_each_xyz()" constructs are
designed to be inherently safe even with no braces, but in this case
it's quite understandable that gcc isn't really able to tell that).
This finally leaves the standard "allmodconfig" build with just a
handful of remaining warnings, so new and valid warnings hopefully will
stand out.

It's a bit much, but all well-contained to kbl code and been tested for a

broke things by considering even eDP disconnected if we fail to get

* 'drm-vmwgfx-fixes' of git://people.freedesktop.org/~syeh/repos_linux:
drm/vmwgfx: Fix error paths when mapping framebuffer

I've also realized that a pile of hang fixes for kbl landed in next, and
no one thought of backporting it to 4.7 - kbl has lost prelim_hw_support
tagging in 4.7-rc1 already. Mika is prepping a topic branch for those,
will send you a separate pull request since it's quite a bit (but should
be all well restricted to kbl code, so similar to polaris in amdgpu).

Dell XPS 13 9350 apparently doesn't like it when we use the panel type
from OpRegion. The OpRegion panel type (0) tells us to use use low
vswing for eDP, whereas the VBT panel type (2) tells us to use normal
vswing. The problem is that low vswing results in some display flickers.
Since no one seems to know how this stuff is supposed to be handled,
let's just ignore the OpRegion panel type on SKL for now.
v2: Print the panel type correctly in the debug output

In commit 7608a43d8f ("locking/mutexes: Use MUTEX_SPIN_ON_OWNER when
appropriate") the owner field in the mutex was updated from being
dependent upon CONFIG_SMP to using optimistic spin. Update our peek
function to suite.

A new set of fixes for the sun4i driver, mostly related to vblank handling,
and a minor fix to release a reference on the device tree nodes we're
parsing in the probe logic.
