So we can skip the locking. Also renames sw_int to
ring_int, cause that better matches its purpose.

1. It is really dangerous to have more than one
spinlock protecting the same information.
2. radeon_irq_set sometimes wasn't called with lock
protection, so it can happen that more than one
CPU would tamper with the irq regs at the same
time.
3. The pm.gui_idle variable was assuming that the 3D
engine wasn't becoming idle between testing the
register and setting the variable. So just remove
it and test the register directly.
v2: Also handle the hpd irq code the same way.
v3: Rename hpd parameter for clarification.

The spinlock was actually there to protect the
rptr, but rptr was read outside of the locked area.
Also we don't really need a spinlock here, an
atomic should to quite fine since we only need to
prevent it from being reentrant.
v2: Keep the spinlock....
v3: Back to an atomic again after finding & fixing the real bug.

It is completely unnecessary to create fences
before they are emitted, so remove it and a bunch
of checks if fences are emitted or not.

- Properly set up the RBs
- Properly set up the SPI
- Properly set up gb_addr_config
This should fix rendering issues on certain cards.

This adds prime->fd and fd->prime support to radeon.
It passes the sg object to ttm and then populates
the gart entries using it.
Compile tested only.
v2: stub kmap + use new helpers + add reimporting

All radeon_gem_init() does is initialize the gem objects
list. radeon_device.c does this explicitly. r600+ calls
radeon_gem_init() so the list gets initialized twice. Older
asics don't call it at all and rely on the the init in
radeon_device.c. Just call radeon_gem_init() in radeon_device.c
and remove the explicit calls from all the newer asics.
All asics call radeon_gem_fini() in their fini pathes. That
could possibly be cleaned up too.

Directly use the suballocator to get small chunks of memory.
It's equally fast and doesn't crash when we encounter a GPU reset.

Conflicts:
drivers/gpu/drm/i915/intel_display.c
Ok, this is a fun story of git totally messing things up. There
/shouldn't/ be any conflict in here, because the fixes in -rc6 do only
touch functions that have not been changed in -next.
The offending commits in drm-next are 14415745b2..1fa611065 which
simply move a few functions from intel_display.c to intel_pm.c. The
problem seems to be that git diff gets completely confused:
$ git diff 14415745b2..1fa611065
is a nice mess in intel_display.c, and the diff leaks into totally
unrelated functions, whereas
$git diff --minimal 14415745b2..1fa611065
is exactly what we want.
Unfortunately there seems to be no way to teach similar smarts to the
merge diff and conflict generation code, because with the minimal diff
there really shouldn't be any conflicts. For added hilarity, every
time something in that area changes the + and - lines in the diff move
around like crazy, again resulting in new conflicts. So I fear this
mess will stay with us for a little longer (and might result in
another backmerge down the road).

This closes a race seen with kexec where we enable PCI bus mastering
but the card has been reinitialised fully yet.
This was previously fixed by a patch from Jerome, but this should
close the race completely.
v2: add SI support as suggested by Alex.

3. ce - constant engine, part of the CP
4. rlc - interrupt controller
5. mc - memory controller
