The locking & protection of radeon object was somewhat messy.
This patch completely rework it to now use ttm reserve as a
protection for the radeon object structure member. It also
shrink down the various radeon object structure by removing
field which were redondant with the ttm information. Last it
converts few simple functions to inline which should with
performances.

We really don't need to process every irq that comes in, we only
really want to do SW irq processing when we are actually waiting for
a fence to pass. I'm not 100% sure this is race free esp on non-MSI systems
so it needs some testing.

This enables the use of interrupts on r6xx/r7xx hardware.
Interrupts are implemented via a ring buffer.  The GPU adds
interrupts vectors to the ring and the host reads them off
in the interrupt handler.  The interrupt controller requires
firmware like the CP.  This firmware must be installed and
accessble to the firmware loader for interrupts to function.

MSIs don't seem to work on my RS780.  They work fine on all
my discrete cards.  I'm not sure about other RS780s or
RS880s.  I've disabled MSIs on RS780 and RS880, but it would
probably be worth checking on some other systems.

Some systems have multiple connectors connected to the same encoder;
e.g., DVI and HDMI connected to the same encoder with the same ddc
line. Since we expose connectors as xrandr outputs, randr treats them
separately which results in it trying to source the same encoder to
different crtcs. If we have an HDMI and DVI-D port on the same encoder,
pick the one to be considered connected based on the edid (HDMI if edid
indicates HDMI, DVI otherwise).

This prevents us from enabling the scaler when it's

mode).  Also, always set the adjusted mode equal
to the native mode for lvds.

With flatmem hibernation for Loongson will fail, and there are also some
other problems such as broken files when using NFS or CIFS / Samba.

The config help of sparsemem says:

"This option provides some potential performance benefits, along with
decreased code complexity."

So to avoid the potential problems of FLATMEM, we disable FLATMEM directly
and use SPARSEMEM instead.

Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on:

Kernel panic - not syncing: Attempted to kill init!

The possible reason is the cache aliases problem:

Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger
then 4kb. so, If using 4kb page size, there is cache aliases problem.
To avoid this kind of problem, extra cache flushing.  The 2nd possible
solution is 16kb page size which avoids cache aliases without the need for
extra cache flushes.  So we disable 4kB pages until the aliasing issue is
solved.
