For the amd64 we need to do some extra stack alignment fixups. Otherwise

we can end up with some threads with a non-16-byte-aligned stack. This causes some interesting side effects, including general protection faults leading to a SIGBUS when doing floating point or varargs. This should be just a verbose NOP for the other platforms. Approved by: re (scottl)

Increase the scheduler stack to 4 pages. This should prevent a stack

Port libc_r to ia64. We need to do things slightly different

2003-01-06T00:56:23Z

because we have 2 stacks per thread: the regular downward memory stack and the irregular upward register stack. This implementation lets both stacks grow toward each other. An alternative scheme is to have them grow away from each other. The alternate scheme has the advantage that both stack grow toward guard pages. Since libc_r is virtually dead and we really want the *context stuff for thread switching, we don't try to be perfect, just functional.
