Apparently xf86-video-vmware leaves the mode->type uninitialized
when feeding the mode to the kernel. Thus we have no choice but
to accept the garbage in. We'll just ignore any of the bits we
don't want. The mode type is just a hint anyway, and more
useful for the kernel->userspace direction.

After resetting the GPU (or subset of engines), call synchronize_irq()
to flush any pending irq before proceeding with the cleanup. For a
device level reset, we disable the interupts around the reset, but when
resetting just one engine, we have to avoid such global disabling. This
leaves us open to an interrupt arriving for the engine as we try to
reset it. We already do try to flush the IIR following the reset, but we
have to ensure that the in-flight interrupt does not land after we start
cleaning up after the reset; enter synchronize_irq().
As it current stands, we very rarely, but fatally, see sequences such as:
2.... 57964564us : execlists_reset_prepare: rcs0
2.... 57964613us : execlists_reset: rcs0 seqno=424
0d.h1 57964615us : gen8_cs_irq_handler: rcs0 CS active=1
2d..1 57964617us : __i915_request_unsubmit: rcs0 fence 29:1056 <- global_seqno 1060
2.... 57964703us : execlists_reset_finish: rcs0
0..s. 57964705us : execlists_submission_tasklet: rcs0 awake?=1, active=0, irq-posted?=1
v2: Move the sync into the execlists reset handler so that we coordinate
the flush with disabling the interrupt handling and canceling the
pending interrupt.
v3: Just use synchronize_hardirq() to avoid the might_sleep(), we do not
yet have threaded-irq to worry about.

Using engine->irq_posted for execlists, we are not always serialised by
the tasklet as we supposed. On the reset paths, the tasklet is disabled
and ignored. Instead, we manipulate the engine->irq_posted directly to
account for the reset, but if an interrupt fired before the reset and so
wrote to engine->irq_posted, that write may not be flushed from the
local CPU's cacheline until much later as the tasklet is already active
and so does not generate a mb(). To correctly serialise the interrupt
with reset, we need serialisation on the set_bit() itself.
And at last Mika can be happy.

Both request_submit and request_unsubmit deal with transferring the
request from the client's timeline onto the execution timeline and back
again. As both functions deal with a pair of timeline's, using a
shorthand for just one of them is slightly confusing, especially as the
different functions use the shorthand for the alternate timeline.
Instead, use the full version of each timeline so it should be easier to
keep track of the transfer between the request/client and the engine.

DRM_VMW_EVENT_FENCE_SIGNALED (struct drm_vmw_event_fence) and
DRM_EVENT_VBLANK (struct drm_event_vblank) pass timestamps in 32-bit
seconds/microseconds format.
As of commit c61eef726a78 ("drm: add support for monotonic vblank
timestamps"), other DRM drivers use monotonic times for drm_event_vblank,
but vmwgfx still uses CLOCK_REALTIME for both events, which suffers from
the y2038/y2106 overflow as well as time jumps.
For consistency, this changes vmwgfx to use ktime_get_ts64 as well,
which solves those problems and avoids the deprecated do_gettimeofday()
function.
This should be transparent to to user space, as long as it doesn't
compare the time against the result of gettimeofday().

We were relying on the pinned screen object backup buffer to be destroyed
when not used. But if we hold a copy of the atomic state, like when
hibernating, the backup buffer might not be destroyed since it's
refcounted by the atomic state. This causes us to hibernate with a
buffer pinned in VRAM.
Fix this by only having the buffer pinned when it is actually used by a
screen object.

fbdev framebuffers were previously pinned to be able to keep them mapped

This commit introduces a mechanism that instead revalidates the map on

down if the underlying pages change. Typically on buffer object moves and
swapouts.
This should be nicer to the system when we have resource contention.

The utility uses kmap_atomic() instead of vmapping the whole buffer
object. As a result there will be more book-keeping but on some
architectures this will help avoid exhausting vmalloc space and also
avoid expensive TLB flushes.
The blit utility also adds a provision to compute a bounding box of
changed content, which is very useful to optimize presentation speed
of ill-behaved applications that don't supply proper damage regions, and
for page-flips. The cost of computing the bounding box is not that
expensive when done in a cpu-blit utility like this.

A few more fixes for 4.16. Mostly for displays:
- A fix for DP handling on radeon
- Fix banding on eDP panels
- Fix HBR audio
- Fix for disabling VGA mode on Raven that leads to a corrupt or
blank display on some platforms
* 'drm-fixes-4.16' of git://people.freedesktop.org/~agd5f/linux:
drm/amd/display: Add one to EDID's audio channel count when passing to DC
drm/amd/display: We shouldn't set format_default on plane as atomic driver
drm/amd/display: Fix FMT truncation programming
drm/amd/display: Allow truncation to 10 bits
drm/amd/display: fix dereferencing possible ERR_PTR()
drm/amd/display: Refine disable VGA
drm/amdgpu: Use atomic function to disable crtcs with dc enabled
drm/radeon: Don't turn off DP sink when disconnected

HSW and BDW have SRD_AUX_{CTL, STATUS} registers that the driver needs to
setup for the HW to use whenever exiting PSR. SKL+ hardware use hardcoded
values for the same and do not need any registers to be setup. So, use
drm_dp_dpcd_writeb() for a one-time write during PSR enable and setup the
PSR aux registers on HSW and BDW for later use by HW.
We also end up writing to reserved bits in SRD_AUX_CTL by reusing
intel_dp->get_aux_send_ctl() for HSW and BDW, fix this.
Since the AUX register setup is source side programming, move the call
to enable_source() from enable_sink().
