Thank you for the quick and friendly review! This is my first feature
submission to the kernel. I've only sent some bug fixes earlier, so
that's much appreciated.

Good point. 

Sparc has its own PTRACE_GETREGS64/PTRACE_SETREGS64 requests that
transfer the uapi struct pt_regs directly from <asm/ptrace.h>, so thel
ocal definition wasn't needed after all.

One small quirk I hit though. The requests use the historical layout
that omits %g0, so the transferred block starts at %g1 and every u_regs
index is one lower than the register number suggests (%g1 is u_regs[0],
%o0 is u_regs[7]). 

Will post v2 with a comment saying so now. Re-ran the suite on
the T4-1 with the new version: still 95 of 95.
