CVS commit: [nathanw_sa] syssrc/sys

[Nathan J Williams <nathanw%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   nathanw
Date:           Sat Nov  9 02:30:07 UTC 2002

Modified Files:
        syssrc/sys/kern [nathanw_sa]: kern_sa.c
        syssrc/sys/sys [nathanw_sa]: savar.h

Log Message:
Remove the stack reservation hack; it has the unpleasant side effect
of placing an upper bound on the number of LWPs that can be in the kernel.
Instead, if we run out of stacks in sa_upcall_userret(), turn of the SA flag
for the LWP and sleep on the stack count. sa_stacks() then wakes up on that
count.

Also a little bit of whitespace cleanup.
