Changeset 31402 in vbox for trunk/src/VBox/VMM/PATM

Message:

PGM: Replaced the hazzardous raw-mode context dynamic mapping code with the PGMR0DynMap code used by darwin/x86. This is a risky change but it should pay off once stable by providing 100% certainty that dynamically mapped pages aren't resued behind our back (this has been observed in seemingly benign code paths recently).
