Fix the SIS DRM memory allocator if the SIS FB built as a module. The SIS DRM
code initialises the mm allocation hooks, but _only_ if the SIS FB is not
built as a module because it depends on CONFIG_FB_SIS, and that's unset if the
SIS FB is not built in. It must check CONFIG_FB_SIS_MODULE as well.

If this triggers its bad, however some machines seem to have been
triggering it for ages and we didn't know until we added the debug.
So downgrade the debug now so people don't call this a regression.

* 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
drm: don't set the signal blocker on the master process.
drm: don't call the vblank tasklet with irqs disabled.
r300: Fix cliprect emit
drm/radeon: r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEX
radeon: fix some hard lockups on r3/4/500s
There is a problem with debugging the X server and gdb crashes in
the xkb startup code.
This avoids the problem by allowing the master process to get signals.
It should be safe as the signal blocker is mainly so that you can
Ctrl-Z a 3D application without locking up the whole box. Ctrl-Z the
X server isn't something many people do.

If a specific tasklet shares data with irq context,
it needs to take a private irq-blocking spinlock within
the tasklet itself.

This makes our handling of cliprects sane. drm_clip_rect always has exclusiv
bottom-right corners, but the hardware expects inclusive bottom-right corner
so we adjust this here.
This complements Michel Daenzer's commit 57aea290e1e0a26d1e74df6cff777eb9f03
to Mesa. See also http://bugs.freedesktop.org/show_bug.cgi?id=16123

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.

This patch should fix hard lockup and convert them in
softlockup (ie you can ssh the box but the gpu is busted
and we are waiting in loop for it to come back to reason).

Some module parameters with only one line have the '\n' at the end of the
description. This is not needed nor wanted as after the description the
type (i.e. int) is followed by a newline.
Some modules contain a multi-line description, these are not affected
by this patch.

With new userspace libpciaccess we can get a conflicting mapping

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.
This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
