:I revisited these two kernel files and agree partially with your assessment:
:- machdep.c fixed a missing linebreak; the other change (mc_len) was cruft.
:- ucontext.h contains the protos for the *context routines; they still need
:to be somewhere so autoconf can find them, and I felt that this was the best
:place for them. The other stuff (uc_flags, UCF_SWAPPED) was cruft.

Ok, I restored those bits.
I have implemented the assembly and done some other cleanups and a
bit of testing. I am committing the completed work now.
I have not yet implemented the floating point save/restore. I will
check save-used for FP registers and see if I can optimize what gets
saved. When switching occurs synchronously I don't think the FP regs
need to be saved/restored unless the prorgam is compiled to use
FP regs and general regs so this may be good enough for the moment.
Switching from a signal dispatch is more problematic. That almost
certainly requires FP save/restore.
Now we need some comprehensive testing with packages that actually
use this beast!
