CVS commit: [wrstuden-revivesa] src/sys/kern

[Bill Stouder-Studenmund <wrstuden%netbsd.org@localhost>]

Module Name:    src
Committed By:   wrstuden
Date:           Sat Jun 28 21:35:03 UTC 2008

Modified Files:
        src/sys/kern [wrstuden-revivesa]: kern_sa.c

Log Message:
While we can't use sa_mutex for the upcall list, some of the
sa_mutex locking calls were needed as we were getting stacks. Put
them back.

Clean up vestigial code that tries to use p_lock instead of sa_mutex.
Clean up some other warts in sa_increaseconcurrency.

Comment out some code that modified the # of lwps in the process.
We didn't copy that behavior from 4.0 yet as it will need an
auditing of the rest of the kernel.

If sa_switchcall comes back from mi_switch, exit. The only two ways
out of the lwp cache are either getting re-used (including cpu_setfunc())
or the process's exiting.
