A critical 3.18 regression fix from Rob, (thanks!)
A fix to avoid advertizing modes we can't support from Sinclair
  (welcome Sinclair!)
and a fix for an incorrect  hash key computation from me that is
  completely harmless, but can wait 'til the next merge window if necessary.
  (I can't really bother stable with this one).

  drm/vmwgfx: Fix hash key computation
  drm/vmwgfx: fix lock breakage

When screen objects are enabled, the bpp is assumed to be 32, otherwise
it is set to 16.

v2:
* Use u32 instead of u64 for assumed_bpp.
* Fixed mechanism to check for screen objects
* Limit the back buffer size to VRAM.

The hash key computation in vmw_cmdbuf_res_remove incorrectly didn't take
the resource type into account, contrary to all the other related functions.
This becomes important when the cmdbuf resource manager handles more than
one resource type.

    drm: Handle legacy per-crtc locking with full acquire ctx

drm_mode_cursor_common() was switched to use drm_modeset_(un)lock_crtc()
which uses full aquire ctx.  So dropping/reaquiring the lock via
drm_modeset_(un)lock() directly isn't the right thing to do, as lockdep
kindly points out.

The 'FIXME's about sorting out whether vmwgfx *really* needs to lock-all
for cursor updates still apply.

Three changes for the Armada DRM driver:
1. Add back the flags which tell the DRM core that we can do vblank.  This
   was removed in error during the recent restructuring, and came to light
   while trying textured Xv rendering.

2. Fixing a refcount leak with Xv overlay.

3. As per recent discussion, the drm_vblank_pre_modeset() calls can cause
   deadlock with other changes to generic code.  This change prevents those
   deadlocks by switching to the drm_crtc_vblank_*() calls instead.

Turning vdd on/off can generate a long hpd pulse on eDP ports. In order
to handle hpd we would need to turn on vdd to perform aux transfers.
This would lead to an endless cycle of
"vdd off -> long hpd -> vdd on -> detect -> vdd off -> ..."

So ignore long hpd pulses on eDP ports. eDP panels should be physically
tied to the machine anyway so they should not actually disappear and
thus don't need long hpd handling. Short hpds are still needed for link
re-train and whatnot so we can't just turn off the hpd interrupt
entirely for eDP ports. Perhaps we could turn it off whenever the panel
is disabled, but just ignoring the long hpd seems sufficient.

Sometimes we seem to get utter garbage from DPCD reads. The resulting
buffer is filled with the same byte, and the operation completed without
errors. My HP ZR24w monitor seems particularly susceptible to this
problem once it's gone into a sleep mode.

The issue seems to happen only for the first AUX message that wakes the
sink up. But as the first AUX read we often do is the DPCD receiver
cap it does wreak a bit of havoc with subsequent link training etc. when
the receiver cap bw/lane/etc. information is garbage.

A sufficient workaround seems to be to perform a single byte dummy read
before reading the actual data. I suppose that just wakes up the sink
sufficiently and we can just throw away the returned data in case it's
crap. DP_DPCD_REV seems like a sufficiently safe location to read here.

Commit 78b81f46 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
when doing the following sequence in loop:

- Boot the kernel
- Perform audio playback
- Reboot the system via 'reboot' command

In many times the audio card cannot be probed, which causes playback to fail.

After restoring to the original i2c0 frequency of 100kHz there is no such
problem anymore.
