CVS commit: src/sys/arch/x86

["Andrew Doran" <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Thu Jan  2 19:20:02 UTC 2020

Modified Files:
        src/sys/arch/x86/include: pmap_pv.h
        src/sys/arch/x86/x86: pmap.c

Log Message:
Replace the pv_hash_locks with atomic ops.

Leave the hash table at the same size for now: with the hash table size
doubled, system time for a build drops 10-15%, but user time starts to rise
suspiciously, presumably because the cache is wrecked.  Need to try another
data structure.
