It looks fine to me, except that I decided to play chicken as far as the
give_sigsegv update of sa_handler is concerned.
Arun, I hope I got the ia32 emulation parts right, but you may want to
double-check.
The patch seems to work fine as far as I have tested. I'm seeing some
oddity in context-switch overhead and pipe latency as reported by LMbench,
but I suspect that's due to another change that happened somewhere between
2.6.5-rc1 and Linus' bk tree as of this morning.
