Last change on this file since 65466 was 65466, checked in by vboxsync, 8 years ago

PGM: Guest page table walking optimizations (incomplete) and statistics.

Optimizing guest page table walking (predictions, eff flags). More to do here, esp. with IEM TLB.
Added a bunch of page pools access handler stats, doing some cleanup while there.
Used bit 9 in PDEs for remembering whether it's from a large or 4KB page. Only for statistics for now.

Property svn:eol-style set to native
