[ros-dev] [ros-diffs] [ros-arm-bringup] 32371: Fixed several off-by-one errors when playing with the PFN database array size. Among other things, certain valid pages would be considered invalid, and also the PFN database wouldn't be properly erased on startup (which would result in a crash after a warm reboot or restarting the emulator).

The off-by-one errors are because MmPageArraySize is:
      MmPageArraySize = MmHighestPhysicalPage;
and not
      MmPageArraySize = MmHighestPhysicalPage + 1;

Just my 2 cents,
Pablo
