Subject: Widen MainMem pagenums.
X-Git-Tag: 2012.03.13-651368~38
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=568df879d1e5fa55d78271f2f49faa2024c79589;p=thirdparty%2Fopen-vm-tools.git

Widen MainMem pagenums.

This change widens the MainMem pagenums to 30 bits, in order to
support up to 4TB of vRAM. BPN_MAINMEM_TAG is bit 30 now. For
non-mainMem BPNs, the slot bits move into bits 23-29.

No monitor size change.
