55a5cb5d59 drm/radeon: Fix printf type warning in 64bit system.
Type of iterator was promoted to unsigned long in 64bit systems.

*header is small structure so it is alwas safe to cast return value
of sizeof operator to int.

b4fe945405 drm/radeon: Fix memory allocation failures in the preKMS command stream checking.
Allocation of single large block of memory may fail under memory
presure. drm_buffer object can hold one large block of data in
multiple independ pages which preents alloation failures.

This patch converts all access to command stream to use drm_buffer
interface. All direct access to array has to go tough drm_buffer
functions to get correct pointer.

Outputting the command stream to ring buffer needs to be awear of
the split nature of drm_buffer. The output operation requires the
new OUT_RING_DRM_BUFFER.

01136acff8 DRM: Rename clamp variable
linux/kernel.h has a "clamp" macro, but r300_cmdbuf also uses a variable
with the same name. Right now it doesn't seem to include the header,
but sooner or later someone will. So better rename the variable
now.

958a6f8ccb drm: radeon: Fix unaligned access in r300_scratch().
In compat mode, the cmdbuf->buf 64-bit address cookie can
potentially be only 32-bit aligned.  Dereferencing this as
64-bit causes expensive unaligned traps on platforms like
sparc64.

Use get_unaligned() to fix.

7c1c2871a6 drm: move to kref per-master structures.
This is step one towards having multiple masters sharing a drm
device in order to get fast-user-switching to work.

It splits out the information associated with the drm master
into a separate kref counted structure, and allocates this when
a master opens the device node. It also allows the current master
to abdicate (say while VT switched), and a new master to take over
the hardware.

It moves the Intel and radeon drivers to using the sarea from
within the new master structures.

649ffc06a6 r300: Fix cliprect emit
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

e2898c5fdd drm/radeon: 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.

54f961a628 radeon: fix some hard lockups on r3/4/500s

softlockup (ie you can ssh the box but the gpu is busted

c0e09200dc drm: reorganise drm tree to be more future proof.
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.
