We want to enable dithering on any pipe where the frame buffer has
more color resolution than the output device.
The previous code was incorrectly clamping the frame buffer bpc to the
display bpc, effectively disabling dithering all of the time as the
computed frame buffer bpc would never be larger than the display bpc.

drm/nv04/crtc: Bail out if FB is not bound to crtc
drm/nouveau: fix nv04_sgdma_bind on non-"4kB pages" archs
drm/nouveau: properly handle allocation failure in nouveau_sgdma_populate
drm/nouveau: fix oops on pre-semaphore hardware
drm/nv50/crtc: Bail out if FB is not bound to crtc
This commit resolves a possible 'NULL pointer dereference'
It uses the same approach as radeon, intel and nouveau/nv50

Not cleaning after alloc failure would result in crash on destroy,
because nouveau_sgdma_clear assumes "ttm_alloced" to be not null when
"pages" is not null.

This bumps driver major version as a result of previous incompatible
interface changes.
In addition, a leftover command definition is removed from the
vmwgfx_drm.h header.
Also a strict version check is enforced on the exebuf ioctl.
This is intended to be the last major bump before exiting staging.

This is needed before we introduce the fence objects.
Otherwise this will be even more confusing. The plan is to use the following:
seqno: A 32-bit sequence number that may be passed in the fifo.
marker: Objects, carrying a seqno, that track fifo submission time. They
are used for fifo lag based throttling.
fence objects: Kernel space objects, possibly accessible from user-space and
carrying a 32-bit seqno together with signaled status.

When GMR2 is available, make sure we restrict the number of used GMR pages
to the limit indicated by the device.
This is done by failing a GMRID allocation if the total number of GMR pages
exceeds the limit.
As a result TTM will then start evicting buffers in GMR memory on a
LRU basis until the allocation succeeds.

Perform all command stream validation in a bounce buffer separate from the
fifo. This makes the fifo available to all validation-generated commands,
which would otherwise attempt to grab the fifo recursively, causing a
deadlock. This is in preparation for GMR2 and swappable surfaces.
Also maintain references to all surfaces in the command stream until the
command stream has been fired in order to avoid racing with surface
destruction taking place after validation but before submission.
