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

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

Module Name:    src
Committed By:   wrstuden
Date:           Sat Jun 28 21:06:31 UTC 2008

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

Log Message:
1) Don't memset(sa, 0, sizeof(*sa)) after we initialize a mutex. That
leads to LOCKDEBUG panics.

2) Be consistent about using savp_mutex to lock savp_upcalls. Some code
was using savp_mutex and some was using sa_mutex. So that led to an
occasionally inconsistent list of upcalls and a kernel panic.

3) Clean up some locking warts in sa_switchcall() as part of (2).
