becee2a57f drm/gem: make drm_gem_object_handle_unreference_unlocked static
No one outside of drm should use this, the official interfaces are
drm_gem_handle_create and drm_gem_handle_delete. The handle refcounting
is purely an implementation detail of gem.

730c4ff95e drm/prime: fix error path in drm_gem_prime_fd_to_handle
handle_unreference only clears up the obj->name and the reference,
but would leave a dangling handle in the idr. The right thing
to do is to call handle_delete.

a8e11d1c43 drm/gem: fix up flink name create race
This is the 2nd attempt, I've always been a bit dissatisified with the
tricky nature of the first one:

http://lists.freedesktop.org/archives/dri-devel/2012-July/025451.html

The issue is that the flink ioctl can race with calling gem_close on
the last gem handle. In that case we'll end up with a zero handle
count, but an flink name (and it's corresponding reference). Which
results in a neat space leak.

In my first attempt I've solved this by rechecking the handle count.
But fundamentally the issue is that ->handle_count isn't your usual
refcount - it can be resurrected from 0 among other things.

For those special beasts atomic_t often suggest way more ordering that
it actually guarantees. To prevent being tricked by those hairy
semantics take the easy way out and simply protect the handle with the
existing dev->object_name_lock.

With that change implemented it's dead easy to fix the flink vs. gem
close reace: When we try to create the name we simply have to check
whether there's still officially a gem handle around and if not refuse
to create the flink name. Since the handle count decrement and flink
name destruction is now also protected by that lock the reace is gone
and we can't ever leak the flink reference again.

Outside of the drm core only the exynos driver looks at the handle
count, and tbh I have no idea why (it's just for debug dmesg output
luckily).

I've considered inlining the drm_gem_object_handle_free, but I plan to
add more name-like things (like the exported dma_buf) to this scheme,
so it's clearer to leave the handle freeing in its own function.

This is exercised by the new gem_flink_race i-g-t testcase, which on
my snb leaks gem objects at a rate of roughly 1k objects/s.

v2: Fix up the error path handling in handle_create and make it more
robust by simply calling object_handle_unreference.

v3: Fix up the handle_unreference logic bug - atomic_dec_and_test
retursn 1 for 0. Oops.

v4: Squash in inlining of drm_gem_object_handle_reference as suggested
by Dave Airlie and add a note that we now have a testcase.

9712def2b3 Merge tag 'drm-intel-next-2013-08-09' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Daniel writes:
New pile of stuff for -next:
- Cleanup of the old crtc helper callbacks, all encoders are now converted
  to the i915 modeset infrastructure.
- Massive amount of wm patches from Ville for ilk, snb, ivb, hsw, this is
  prep work to eventually get things going for nuclear pageflips where we
  need to adjust watermarks on the fly.
- More vm/vma patches from Ben. This refactoring isn't yet fully rolled
  out, we miss the execbuf conversion and some of the low-level
  bind/unbind support code.
- Convert our hdmi infoframe code to use the new common helper functions
  (Damien). This contains some bugfixes for the common infoframe helpers.
- Some cruft removal from Damien.
- Various smaller bits&pieces all over, as usual.

beb2dc0a7a powerpc: Convert some mftb/mftbu into mfspr
Some CPUs (such as e500v1/v2) don't implement mftb and will take a
trap.  mfspr should work on everything that has a timebase, and is the
preferred instruction according to ISA v2.06.

Currently we get away with mftb on 85xx because the assembler converts
it to mfspr due to -Wa,-me500.  However, that flag has other effects
that are undesireable for certain targets (e.g.  lwsync is converted to
sync), and is hostile to multiplatform kernels.  Thus we would like to
stop setting it for all e500-family builds.

mftb/mftbu instances which are in 85xx code or common code are
converted.  Instances which will never run on 85xx are left alone.

5c751c9344 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John W. Linville says:

====================
Regarding the iwlwifi bits, Johannes says:

"We revert an rfkill bugfix that unfortunately caused more bugs, shuffle
some code to avoid touching the PCIe device before it's enabled and
disconnect if firmware fails to do our bidding. I also have Stanislaw's
fix to not crash in some channel switch scenarios."

As for the mac80211 bits, Johannes says:

"This time, I have one fix from Dan Carpenter for users of
nl80211hdr_put(), and one fix from myself fixing a regression with the
libertas driver."

Along with the above...

Dan Carpenter fixes some incorrectly placed "address of" operators
in hostap that caused copying of junk data.

Jussi Kivilinna corrects zd1201 to use an allocated buffer rather
than the stack for a URB operation.

8bcdeaff5e packet: restore packet statistics tp_packets to include drops

ee80fbf301 ("packet: account statistics only in tpacket_stats_u")
cleaned up the getsockopt PACKET_STATISTICS code.
This also changed semantics. Historically, tp_packets included
tp_drops on return. The commit removed the line that adds tp_drops

Do not clear Broadcast/Multicast/Unicast Wake Flag or LanWake in
Config5. This is necessary to preserve WOL state when the driver is
loaded. Although the r8168 vendor driver does not write Config5 (it has
been commented out), Hayes Wang from Realtek said that masking bits like
this is more sensible.

ad07277e82 ACPI / PM: Hold acpi_scan_lock over system PM transitions
Bad things happen if ACPI hotplug events are handled during system
PM transitions, especially if devices are removed as a result.
To prevent those bad things from happening, acquire acpi_scan_lock
when a PM transition is started and release it when that transition
is complete or has been aborted.

This fixes resume lockup on my test-bed Acer Aspire S5 that happens
when Thunderbolt devices are disconnected from the machine while
suspended.

Also fixes the analogous problem for Mika Westerberg on an
Intel DZ77RE-75K board.
