We sometimes lock IB then the ring and sometimes the ring then
the IB. This is mostly due to the IB locking not being well defined
about what data in the structs it actually locks. Define what I
believe is the correct behaviour and gets rid of the lock dep ordering
warning.

GART static one time initialization was mixed up with GART
enabling/disabling which could happen several time for instance
during suspend/resume cycles. This patch splits all GART
handling into 4 differents function. gart_init is for one
time initialization, gart_deinit is called upon module unload
to free resources allocated by gart_init, gart_enable enable
the GART and is intented to be call after first initialization
and at each resume cycle or reset cycle. Finaly gart_disable
stop the GART and is intended to be call at suspend time or
when unloading the module.

radeon_share.h was begining to give problem with include order in
respect of radeon.h. It's easier and also i think cleaner to move
what was in radeon_share.h into radeon.h. At the same time use the
extern keyword for function shared accross the module.

Move mtrr range and memory information printing to radeon_object_init,
this are memory information and initialization common to all GPU and
they better fit in this function. Will also prevent code duplication

We are splitting GPU & modeset init so that it's easier
to abord only remaining GPU init when somethings fails.
We want to always provide enough funcionalities to get
fbcon and a shadowfb X working. Only acceptable error
during initialization are memory allocation failure or
io mapping failure.

If we stop CP and that it's still processing thing GPU hang might
happen, this patch wait for CP idle (the wait can timeout) so we
can avoid shutting down CP at bad time. This is especialy usefull
when reseting the GPU as it seems GPU reset fails to properly reset
CP when the CP wasn't stop after being idle.

This adds the r600 KMS + CS support to the Linux kernel.
The r600 TTM support is quite basic and still needs more
work esp around using interrupts, but the polled fencing
should work okay for now.
Also currently TTM is using memcpy to do VRAM moves,
the code is here to use a 3D blit to do this, but
isn't fully debugged yet.

This adds the command stream checker for the RN50, R100 and R200 cards.
It stops any access to 3D registers on RN50, and does checks

Initially I always meant this code to be shared, but things
ran away from me before I got to it.
This refactors the i915 and radeon kms fbdev interaction layers
out into generic helpers + driver specific pieces.
It moves all the panic/sysrq enhancements to the core file,
and stores a linked list of kernel fbs. This could possibly be
improved to only store the fb which has fbcon on it for panics
etc.
radeon retains some specific codes used for a big endian
workaround.

For Radeon 100- to 500-series, firmware blobs look like:
struct {
__be32 datah;
__be32 datal;
} cp_ucode[256];
For Radeon 600-series, there are two separate firmware blobs:
__be32 me_ucode[PM4_UCODE_SIZE * 3];
__be32 pfp_ucode[PFP_UCODE_SIZE];
For Radeon 700-series, likewise:
__be32 me_ucode[R700_PM4_UCODE_SIZE];
__be32 pfp_ucode[R700_PFP_UCODE_SIZE];
