Re: First cut of PowerPC support in NPTL



Looks pretty good!  I count five, maybe seven, macros in lowlevellock.h
that are machine-dependent, and the rest of that file and all the rest of
the locking code (except spinlocks) can move up to linux/ and be common to
all the machines where compare_and_swap is as good as it gets.

td_ta_map_lwp2thr should not use ps_get_thread_area on machines using a
normal register.  Just use the thread register value from ps_lgetregs with
appropriate arithmetic directly.


Thanks,
Roland
