I want to be able to use REF_CNT from other places in the kernel without
pushing a fence object onto the list of emitted fences.
The current code makes an assumption that every time the acked sequence is
bumped that there's at least one fence on the list that'll be signalled.
This will no longer be true in the near future.

There was once good reasons for wanting the drm to be able to use M2MF etc
on user channels, but they're not relevant anymore. For the general
buffer move case, we've already lost by transferring between vram/sysmem
already so the context switching overhead is minimal in comparison.

Pull kmap_atomic cleanup from Cong Wang.
It's been in -next for a long time, and it gets rid of the (no longer
used) second argument to k[un]map_atomic().
Fix up a few trivial conflicts in various drivers, and do an "evil
merge" to catch some new uses that have come in since Cong's tree.

this driver would be used for wireless display. virtual display
driver has independent crtc, encoder and connector and to use
this driver, user application should send edid data to this driver
from wireless display.

It's handled via external clock. It should already be protected
by the external ss flag, but add an explicit check just in case.
