19 * 00/03/07 davidm Updated pal_cache_flush() to be in sync with PAL v2.6.
20 * 00/03/23 cfleck Modified processor min-state save area to match updated PAL & SAL info
21 * 00/05/24 eranian Updated to latest PAL spec, fix structures bugs, added
22 * 00/05/25 eranian Support for stack calls, and static physical calls
