Eric Anholt ea7b4fdc22 Fix the possibility of sleeping with locks held in sysctls by copying the 
data into temporary variables with the lock held then outputting to
    sysctls with the lock released. Rearranged a little extra code to aid
    this. Note that drm_memory_debug.h hasn't had this fix applied, but I
    consider that code to be just about dead anyway.

Eric Anholt 0cf1887139 - SMPng lock the DRM. This is only partial -- there are a few code paths 
used by root (the X Server) which are not locked. However, it should
    deal with lost-IRQ issues on -current which I think people have been
    experiencing but I am unable to reproduce (though I understand why they
    would occur, because of a bug of mine). Note that most of the locking
    (DRM_LOCK()/UNLOCK()) is all covered by Giant still, so it doesn't
    matter yet.
- Remove locking on FreeBSD-stable and NetBSD. These are covered by the
    fact that there is no reentrancy of the kernel except by interrupts,
    which are locked using spldrm()/splx() instead.

Eric Anholt 929536172c Stylistic preparation for SMPng locking work: DRM_LOCK/DRM_UNLOCK have side 
effects, so make them look like functions (add parenthesis).

Eric Anholt e187d665e4 Add an MIT-style copyright, assigned to myself, to these files. I think 
I've touched enough of the code here, and there was no previous
    copyright. Do some drive-by style fixes while I'm here.

Eric Anholt ad78a613a4 - Remove $FreeBSD$ tags as they weren't too useful and merges are now being 
done through perforce.
- Add copyright headers to drm_os_*bsd.h, still need to research the other
    copyright-less files better.

Eric Anholt a147df879b Remove more gamma DMA infrastructure. Most of this code was copied straight 
from linux, so it could be added back if some driver needed it in the
    future.

Eric Anholt 0bd0dd2300 Merge back from FreeBSD-current, adding FreeBSD ID tags to aid future 
merging. Also includes an update to radeon PCI IDs.
