Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "This has two main sets of fixes:

   - A bunch of Exynos fixes, mainly for their MIC component.

   - vblank regression fixes from Mario, apparantly some changes in 4.4
     caused some vblank breakage on radeon/nouveau, this set fixes all
     the issues seen.

  There is also a revert of one of the MST changse, that I was
  overzealous in including, that broke 30" MST monitors, and two qxl
  fixes"

* FIMXE: Need to replace this hack with proper seqlocks.
*
* Restrict the bump of the software vblank counter to a safe maximum
* value of +1 whenever there is the possibility that concurrent readers
* of vblank timestamps could be active at the moment, as the current
* implementation of the timestamp caching and updating is not safe
* against concurrent readers for calls to store_vblank() with a bump
* of anything but +1. A bump != 1 would very likely return corrupted
* timestamps to userspace, because the same slot in the cache could
* be concurrently written by store_vblank() and read by one of those
* readers without the read-retry logic detecting the collision.
*
* Concurrent readers can exist when we are called from the
* drm_vblank_off() or drm_vblank_on() functions and other non-vblank-
* irq callers. However, all those calls to us are happening with the
* vbl_lock locked to prevent drm_vblank_get(), so the vblank refcount
* can't increase while we are executing. Therefore a zero refcount at
* this point is safe for arbitrary counter bumps if we are called
* outside vblank irq, a non-zero count is not 100% safe. Unfortunately
* we must also accept a refcount of 1, as whenever we are called from
* drm_vblank_get() -> drm_vblank_enable() the refcount will be 1 and
* we must let that one pass through in order to not lose vblank counts
* during vblank irq off - which would completely defeat the whole
* point of this routine.
*
* Whenever we are called from vblank irq, we have to assume concurrent
* readers exist or can show up any time during our execution, even if
* the refcount is currently zero, as vblank irqs are usually only
* enabled due to the presence of readers, and because when we are called
* from vblank irq we can't hold the vbl_lock to protect us from sudden
* bumps in vblank refcount. Therefore also restrict bumps to +1 when
* called from vblank irq.
