0ba5317158 drm/mgag200: Reject modes that are too big for VRAM
A monitor or a user could request a resolution greater than the
available VRAM for the backing framebuffer. This change checks the
required framebuffer size against the max VRAM size and rejects modes
if they are too big. This change can also remove a mode request passed
in via the video= parameter.

774c389fae drm/radeon: don't check mipmap alignment if MIP_ADDRESS is FMASK
The MIP_ADDRESS state has 2 meanings. If the texture has one sample
per pixel, it's a pointer to the mipmap chain. If the texture has
multiple samples per pixel, it's a pointer to FMASK, a metadata buffer
needed for reading compressed MSAA textures. The mipmap
alignment rules do not apply to FMASK.

d808fc8829 drm/radeon: skip MC reset as it's probably not hung
The MC is mostly likely busy (e.g., display requests), not hung
so no need to reset it.  Doing an MC reset is tricky and not
particularly reliable.  Fixes hangs in certain cases.

44498aea29 drm/i915: also disable south interrupts when handling them
From the docs:

  "IIR can queue up to two interrupt events. When the IIR is cleared,
  it will set itself again after one clock if a second event was
  stored."

  "Only the rising edge of the PCH Display interrupt will cause the
  North Display IIR (DEIIR) PCH Display Interrupt even bit to be set,
  so all PCH Display Interrupts, including back to back interrupts,
  must be cleared before a new PCH Display interrupt can cause DEIIR
  to be set".

The current code works fine because we don't get many interrupts, but
if we enable the PCH FIFO underrun interrupts we'll start getting so
many interrupts that at some point new PCH interrupts won't cause
DEIIR to be set.

The initial implementation I tried was to turn the code that checks
SDEIIR into a loop, but we can still get interrupts even after the
loop is done (and before the irq handler finishes), so we have to
either disable the interrupts or mask them. In the end I concluded
that just disabling the PCH interrupts is enough, you don't even need
the loop, so this is what this patch implements. I've tested it and it
passes the 2 "PCH FIFO underrun interrupt storms" I can reproduce:
the "ironlake_crtc_disable" case and the "wrong watermarks" case.

In other words, here's how to reproduce the problem fixed by this
patch:
  1 - Enable PCH FIFO underrun interrupts (SERR_INT on SNB+)
  2 - Boot the machine
  3 - While booting we'll get tons of PCH FIFO underrun interrupts
  4 - Plug a new monitor
  5 - Run xrandr, notice it won't detect the new monitor
  6 - Read SDEIIR and notice it's not 0 while DEIIR is 0

Q: Can't we just clear DEIIR before SDEIIR?
A: It doesn't work. SDEIIR has to be completely cleared (including the
interrupts stored on its back queue) before it can flip DEIIR's bit to
1 again, and even while you're clearing it you'll be getting more and
more interrupts.

Q: Why does it work by just disabling+enabling the south interrupts?
A: Because when we re-enable them, if there's something on the SDEIIR
register (maybe an interrupt stored on the queue), the re-enabling
will make DEIIR's bit flip to 1, and since we'll already have
interrupts enabled we'll get another interrupt, then run our irq
handler again to process the "back" interrupts.

v2: Even bigger commit message, added code comments.

Note that this fixes missed dp aux irqs which have been reported for
3.9-rc1. This regression has been introduced by switching to
irq-driven dp aux transactions with

15239099d7 drm/i915: enable irqs earlier when resuming

help in code sanity, since more and more stuff is interrupt driven.

    drm/i915: Rearrange code to only have a single method for waiting upon the ring

Like in the driver load code we need to make sure that hotplug
interrupts don't cause havoc with our modeset state, hence block them
with the existing infrastructure. Again we ignore races where we might
loose hotplug interrupts ...

Note that the driver load part of the regression has already been

61bc95c1fb DRM/i915: On G45 enable cursor plane briefly after enabling the display plane.
On G45 some low res modes (800x600 and 1024x768) produce a blank
screen when the display plane is enabled with with cursor plane
off.
Experiments showed that this issue occurred when the following
conditions were met:
a. a previous mode had the cursor plane enabled (Xserver).
b. this mode or the previous one was using self refresh. (Thus
   the problem was only seen with low res modes).
The screens lit up as soon as the cursor plane got enabled.
Therefore the blank screen occurred only in console mode, not
when running an Xserver.
It also seemed to be necessary to disable self refresh while briefly
enabling the cursor plane.

Pull btrfs update from Chris Mason:
 "The biggest feature in the pull is the new (and still experimental)
  raid56 code that David Woodhouse started long ago.  I'm still working
  on the parity logging setup that will avoid inconsistent parity after
  a crash, so this is only for testing right now.  But, I'd really like
  to get it out to a broader audience to hammer out any performance
  issues or other problems.

  scrub does not yet correct errors on raid5/6 either.

  Josef has another pass at fsync performance.  The big change here is
  to combine waiting for metadata with waiting for data, which is a big
  latency win.  It is also step one toward using atomics from the
  hardware during a commit.

  Mark Fasheh has a new way to use btrfs send/receive to send only the
  metadata changes.  SUSE is using this to make snapper more efficient
  at finding changes between snapshosts.

  Snapshot-aware defrag is also included.

  Otherwise we have a large number of fixes and cleanups.  Eric Sandeen
  wins the award for removing the most lines, and I'm hoping we steal

9b2ff35753 ext4: enable quotas before orphan cleanup
When using quota feature we need to enable quotas before orphan cleanup
so that changes happening during it are properly reflected in quota
accounting.

262b4662f4 ext4: don't allow quota mount options when quota feature enabled
So far we silently ignored when quota mount options were set while quota
feature was enabled.  But this can create confusion in userspace when
mount options are set but silently ignored and also creates opportunities
for bugs when we don't properly test all quota types.  Actually
ext4_mark_dquot_dirty() forgets to test for quota feature so it was
dependent on journaled quota options being set.  OTOH ext4_orphan_cleanup()
tries to enable journaled quota when quota options are specified which is
wrong when quota feature is enabled.
