radeon: fix error in busmaster enable logic
...
- logic was wrong. rs400/rs480 should clear the RADEON_BUS_MASTER_DIS bit
- should fix kernel bug 11798

drm/i915: fix ioremap of a user address for non-root (CVE-2008-3831)
...
Olaf Kirch noticed that the i915_set_status_page() function of the i915
kernel driver calls ioremap with an address offset that is supplied by
userspace via ioctl. The function zeroes the mapped memory via memset
and tells the hardware about the address. Turns out that access to that
ioctl is not restricted to root so users could probably exploit that to
do nasty things. We haven't tried to write actual exploit code though.
It only affects the Intel G33 series and newer.

This makes our handling of cliprects sane. drm_clip_rect always has exclusive

r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEX
...
DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour
is undefined (i.e. lockups happen) when this write is not followed by the
right number of vertex indices.
Thus we used to do the wrong thing when drawing across many cliprects was
necessary, because we emitted a sequence
DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER
instead of
DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER
The latter is what we're doing now and which ought to be correct.

i915: Move all of the irq install/uninstall to load time.

This resolves a panic on FreeBSD which was caused by trying

initialize all of the locks at load time. It should also
ensure that the vblank structures are available earlier.
