Subject: [9/9] drm/nouveau: bump version to 1.0.0
commit f887c425f9eeed8ffbca64c8be45da62b07096c0 upstream.
The time has come to get a proper version number that we can change to
indicate new features etc, rather than the lock-step 0.0.XX that we
previously had.
libdrm has recognised this version as compatible with 0.0.16 since 2.4.22,
so hopefully any breakage people see should be very minimal.

Subject: [3/9] drm/nouveau: move fence sequence check to start of loop
commit b08abd4e9a11d637d3c2ff52b2ebbc1b3f686d06 upstream.
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.

commit b5b2e5988bd18a2f6e3f192adf7439599de00d3f upstream.
These are FIFO methods, it doesn't matter what subchannel is being used.

Subject: [1/9] drm/nouveau/ttm: always do buffer moves on kernel channel
commit accf94969f226ddfe7dd3a6a76ce093ace839b26 upstream.
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.

This happens somehow during init on a machine I have, and leads to a

Lets avoid that...
