sys/arch/sparc/sparc/pmap.c: revision 1.366
switch sparc pmap lock to the scheme sparc64 uses:
- - local IPL_NONE mutex for general pmap locking operations, not
kernel lock.
- - for pmap_activate()/pmap_deactivate(), switch to using the
existing ctx_lock, and push handling of it into ctx_alloc() the
ctx_free() callers.
fixes easy to trigger deadlocks on systems with >2 cpus. without
this patch i usually hang during boot. with it, i was able to
push the machine hard for over 12 hours.
XXX: pullup-8, and maybe -7.
