Like this idea, but if we're not going to build DRM I see no
point adding the

My knowledge of the DRM is weak, but as I understand it, the only time
it is used is by the ioctl handlers, and not by userspace. I've added
Dave Airlie to the CC list, hopefully he can enlighten us as to where
else cmpxchg is used.

I don't see what the problem is? If we can't do it in userspace, we fall
back to a heavyweight ioctl lock. This sounds sensible to me.
On parisc we implement userspace CAS with a lightweight syscall on our
gateway

PS: Anyone have a nice prebuilt i386-sparc{32,64} xcompiler setup
I could snag? Would be nice to testbuild these patches before I send
them out next time.

If it's a build issue, simply disallow DRM to be turned on for
SPARC32.
I was really wondering about this one. I'd assumed DRM was already
conditionalized out for sparc32.
