ReactOS Portable Systems Group 2e1b82cf72 NMI Support Patch 1:
[HAL]:  The I/O Permissions Map on a typical Privileged Mode x86 OS is all 0xFF's, so it's quite wasteful to copy-in/out the entire map each single BIOS Call. As an optimization, only save and restore non-0xFF entries.
    [NTOS]: Define and use constants for different IOPM values, instead of using hardcoded values.
