Modified Files:
src/sys/arch/alpha/alpha: pmap.c
Log Message:
Fix a couple of latent MP issues in the Alpha pmap:
- In pmap_activate(), even though we manipulate the active mask
with atomic ops, the lev1map pointer needs to stay consistent,
so we do, in fact, have to take the pmap lock there.
- In pmap_emulate_reference(), some of the DEBUG checks done here
are race-prone, so don't do them. (Leave them #if 0'd out for
documentary purposes.)
