a45440f05e autofs4 - fix get_next_positive_subdir()
Following a report of a crash during an automount expire I found that
the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong.
Not only is the locking wrong but the function is more complex than it
needs to be.

The function is meant to calculate (and dget) the next entry in the list
of directories contained in the root of an autofs mount point (an autofs
indirect mount to be precise). The main problem was that the d_lock of
the owner of the list was not being taken when walking the list, which
lead to list corruption under load. The only other lock that needs to
be taken is against the next dentry candidate so it can be checked for
usability.

Otherwise we still have another gmbus regression (patches are awaiting

entering rc6 often enough (and hence blowing through too much power).  It
seems to be a timing-related issue and can be mitigated by frobbing the
magic tuning parameters. We're still working on that one. Also, we still
have some fallout from the hw context support, but you can only hit that
with mesa master."

2856cc2e4d sparc64: Be less verbose during vmemmap population.
On a 2-node machine with 256GB of ram we get 512 lines of
console output, which is just too much.

This mimicks Yinghai Lu's x86 commit c2b91e2eec
(x86_64/mm: check and print vmemmap allocation continuous) except that
we aren't ever going to get contiguous block pointers in between calls
so just print when the virtual address or node changes.

This decreases the output by an order of 16.

Also demote this to KERN_DEBUG.

7d54a90428 drm/i915: Apply post-sync write for pipe control invalidates
When invalidating the TLBs it is documentated as requiring a post-sync
write. Failure to do so seems to result in a GPU hang.

Exposure to this hang on IVB seems to be a result of removing the extra
stalls required for SNB pipecontrol workarounds:

Note: Manually switch the pipe_control cmd to 4 dwords to avoid a
(silent) functional conflict with -next. This way will get a loud (but
conflict with next (since the scratch_addr has been deleted there).

35a38556d9 drm/i915: reorder edp disabling to fix ivb MacBook Air
eDP is tons of fun. It turns out that at least the new MacBook Air 5,1
model absolutely doesn't like the new force vdd dance we've introduced
in

commit 6cb49835da
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Sun May 20 17:14:50 2012 +0200

    drm/i915: enable vdd when switching off the eDP panel

But that patch also tried to fix some neat edp sequence issue with the
force_vdd timings. Closer inspection reveals that we've raised
force_vdd only to do the aux channel communication dp_sink_dpms. If we
move the edp_panel_off below that, we don't need any force_vdd for the
disable sequence, which makes the Air happy.

Unfortunately the reporter of the original bug that the above commit
fixed is travelling, so we can't test whether this regresses things.
But my theory is that since we don't check for any power-off ->
force_vdd-on delays in edp_panel_vdd_on, this was the actual
root-cause of this failure. With that force_vdd dance completely
eliminated, I'm hopeful the original bug stays fixed, too.

For reference the old bug, which hopefully doesn't get broken by this:

https://bugzilla.kernel.org/show_bug.cgi?id=43163

In any case, regression fixers win over plain bugfixes, so this needs
to go in asap.

v2: The crucial pieces seems to be to clear the force_vdd flag
uncoditionally, too, in edp_panel_off. Looks like this is left behind
by the firmware somehow.

v3: The Apple firmware seems to switch off the panel on it's own, hence
we still need to keep force_vdd on, but properly clear it when switching
the panel off.

cee25168e9 drm/i915: ensure i2c adapter is all set before adding it
i2c_add_adapter() may do i2c transfers on the bus to detect supported
devices. Therefore the adapter needs to be all set before adding it. This
was not the case for the bit-banging fallback, resulting in an oops if the
device detection GMBUS transfers timed out. Fix the issue by calling
i2c_add_adapter() only after intel_gpio_setup().

Most of the checking seems to be in place already. As you can see,
log2(number of samples) resides in LAST_LEVEL.

This is required for MSAA support (namely for depth-stencil resolve and
blitting between MSAA resources).

e43b5ec05a drm/radeon: fence virtual address and free it once idle v4
Virtual address need to be fenced to know when we can safely remove it.
This patch also properly clear the pagetable. Previously it was
serouisly broken.

Kernel 3.5/3.4 need a similar patch but adapted for difference in mutex locking.

v2: For to update pagetable when unbinding bo (don't bailout if
    bo_va->valid is true).
v3: Add kernel 3.5/3.4 comment.
v4: Fix compilation warnings.

81ee8fb6b5 drm/radeon: do not reenable crtc after moving vram start address
It seems we can not update the crtc scanout address. After disabling
crtc, update to base address do not take effect after crtc being
reenable leading to at least frame being scanout from the old crtc
base address. Disabling crtc display request lead to same behavior.

So after changing the vram address if we don't keep crtc disabled
we will have the GPU trying to read some random system memory address
with some iommu this will broke the crtc engine and will lead to
broken display and iommu error message.

So to avoid this, disable crtc. For flicker less boot we will need
to avoid moving the vram start address.

This patch should also fix :

4a5a418462 leds: renesas: fix error handling
bfe4c041 "leds: convert Renesas TPU LED driver to devm_kzalloc() and
cleanup error exit path" introduced a possible case in which r_tpu_probe
calls iounmap on a wild pointer. This changes the one case that was
missed in the same way as the other error paths.

Without this patch, building kota2_defconfig results in:

drivers/leds/leds-renesas-tpu.c: In function 'r_tpu_probe':
drivers/leds/leds-renesas-tpu.c:246:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized]

Pull networking changes from David Miller:
 "Most importantly this should cure the ipv4-mapped ipv6 socket TCP
  crashes some people were seeing, otherwise:

   1) Fix e1000e autonegotiation handling regression, from Tushar Dave.

   2) Fix TX data corruption race on e1000e down, also from Tushar Dave.

   3) Fix bfin_sir IRDA driver build, from Sonic Zhang.

   4) AF_PACKET mmap() tests a flag in the TX ring shared between
      userspace and the kernel for an internal consistency check.  It
      really shouldn't do this to validate the kernel's own behavior
      because the user can corrupt it to be any value at all.  From
      Daniel Borkmann.

   5) Fix TCP metrics leak on netns dismantle, from Eric Dumazet.

   6) Orphan the anonymous TCP socket from the SKB in
      ip_send_unicast_reply() so that the rest of the stack needn't see
      it.  Otherwise we get selinux problems of all sorts, from Eric
      Dumazet.

      This is the best way to fix this since the socket is just a place
      holder for sending packets in a context where we have no real
      socket at all.

   7) Fix TUN detach crashes, from Stanislav Kinsbursky.

   8) dev_set_alias() leaks memory on krealloc() failure, from Alexey
      Khoroshilov.

   9) FIB trie must use call_rcu() not call_rcu_bh(), because this code
      is not universally invoked from software interrupts.  From Eric
      Dumazet.

  10) PPTP looks up ipv4 routes with the wrong network namespace, fix
