Tor Egge	5d183e9691	Change simple lock handling to not depend upon having a local apic ... available. The per-cpu variable ss_tpr has been replaced by ss_eflags. This reduced the number of interrupts sent to the wrong CPU, due to the cpu having the global lock being inside a critical region. Remove some unneeded manipulation of tpr register in mplock.s. Adjust code in mplock.s to be aware of variables on the stack being destroyed by MPgetlock if GRAB_LOPRIO is defined.	1998-05-17 23:08:04 +00:00
Tor Egge	5931a9c24e	For SMP, use prv_PPAGE1/prv_PMAP1 instead of PADDR1/PMAP1. ... get_ptbase and pmap_pte_quick no longer generates IPIs. This should reduce the number of IPIs during heavy paging.	1998-05-17 18:53:19 +00:00
