804d74abe2 drm: use drm_compat_ioctl for 32-bit apps
Most of the DRM drivers appear to be missing the .compat_ioctl file
operation entry necessary for 32-bit application compatibility.

This patch  uses drm_compat_ioctl for all drivers which don't have
their own, and which are using drm_ioctl for .unlocked_ioctl.

This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
.unlocked_ioctl and will presumably need a custom .compat_ioctl as
well.

4dbdf0aea9 drm/mgag200: fix null pointer dereference
we are referencing the pointer after doing alloc_apertures,
as alloc_apertures kzallocs, the kzalloc may fail and we get a NULL.

so we need to check for NULL before we dereference this pointer

08ef8e41a6 drm/mgag200: kick off conflicting framebuffers earlier.
It appears grub2 can pass framebuffer info via efifb, so
we need to kick it off earlier to reserve the vram allocation.

(just a fixup same as for cirrus)

414c453106 mgag200: initial g200se driver (v2)
This is a driver for the G200 server engines chips,
it doesn't driver any of the Matrix G series desktop cards.

It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards.

Its based on previous work done my Matthew Garrett but remodelled
to follow the same style and flow as the AST server driver. It also
works along the same lines as the AST server driver wrt memory management.

There is no userspace driver planned, xf86-video-modesetting should be used.
It also appears these GPUs have no ARGB hw cursors.

v2: add missing tagfifo reset + G200 SE memory bw setup pieces.
