protmemen:
Enable Protected Memory PROT_LOW_BASE/LIMIT and
PROT_HIGH_BASE/LIMIT memory regions.
Software can use the protected low/high address ranges to protect both the
DMA remapping tables and the interrupt remapping tables. There is no
separate set of registers provided for each.
30:1 RV - Reserved.
0:0 RO_V 0x0
protregionsts:
This bit is set by the processor whenever it has completed enabling the
protected memory region per the rules stated in the Intel
