Changeset 38953 in vbox for trunk/src/VBox/VMM/VMMAll/PGMAllBth.h

Message:

PGM: Attempt at fixing the VERR_MAP_FAILED during state save problem on 32-bit hosts when assigning lots of memory to the guest. PGM should lock down guest RAM pages before use and release them afterwards like everyone else. Still quite some stuff left to do there, so I've deviced a little hack for tracking unlocked mappings and using this as input when deciding to do async or sync chunk unmapping at save/load time. See xtracker #5912 and public ticket 7929.
