Log Message:
Add an optimization for UP system with non-virtually tagged caches (which are
most of them these days).
If a page needs to be have an icache_sync performed and the page has a direct
map alias (XKPHYS or KSEG0), then don't do an index op; instead do a range op
on the XKPHYS or KSEG0 address. This results in unneeded fewer cache line
invalidations.
