This is great!

One issue I can think about is that on hppa stack grows up.
I believe it's the only architecture currently in use where
stack grows up.


Also, the following comment should be changed from

/* IA-64 architecture -- needs a faster context switcher since gcc sucks */

to something like that:

/*
 * Besides traditional memory call stack, IA-64 uses general register
 * stack. Thus each thread needs a backing store for register stack in
 * addition to memory stack. Standard setjmp()/longjmp() cannot be used
 * for thread context switching because their implementation implicitly
 * assumes that only one register stack exists.
