1d930fc75b 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.

739b01dde4 i915: Clear sarea_priv during lastclose. 
sarea_priv needs to be NULL before i915_initialized is called to
properly reset it.  The stale value produces a panic any time something
opens/closes drm without calling initialize.  i.e. version checking

90b90c65dc r300: Fix cliprect emit 
This makes our handling of cliprects sane. drm_clip_rect always has exclusive
bottom-right corners, but the hardware expects inclusive bottom-right corners,
so we adjust this here.

This complements Michel Daenzer's commit 57aea290e1e0a26d1e74df6cff777eb9f038f1f8
to Mesa. See also http://bugs.freedesktop.org/show_bug.cgi?id=16123 .

f85fd1b42d intel-gem: Speed up tiled readpixels by tracking which pages have been flushed. 
This is around 3x or so speedup, since we would read wide rows at a time, and
clflush each tile 8 times as a result.  We'll want code related to this anyway
when we do fault-based per-page clflushing for sw fallbacks.

c3d463840c 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.

965a72202b i915: Move all of the irq install/uninstall to load time. 
This resolves a panic on FreeBSD which was caused by trying
to re-initialize the swap lock.  It's just much easier to
initialize all of the locks at load time.  It should also
ensure that the vblank structures are available earlier.
