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

Module Name:    src
Committed By:   wrstuden
Date:           Tue Jul  1 19:06:34 UTC 2008

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

Log Message:
Add a debug message in sa_upcall0() to indicate what type, event, and
interrupted parameters we get.

Scoot the panic in sa_switch() (which really can't happen anymore) to
the right a few tabs so that diff -p won't think it's a routine name.

In the LP_SA_PAGEFAULT handling code, reset the cache lwp to use
sa_neverrun (which just exits) rather than sa_switchcall with
a NULL arguement. Also add a debug message indicating we are doing
pagefault handling.

sa_switchcall() assert we are teh blessed lwp.

sa_unblock_userret(): uvm_lwp_hold() before going to sleep. Balances
the uvm_lwp_unholds we have.
