17 * 99/10/01 davidm Make sure we pass zero for reserved parameters.
18 * 00/03/07 davidm Updated pal_cache_flush() to be in sync with PAL v2.6.
19 * 00/03/23 cfleck Modified processor min-state save area to match updated PAL & SAL info
20 * 00/05/24 eranian Updated to latest PAL spec, fix structures bugs, added
21 * 00/05/25 eranian Support for stack calls, and static physical calls
22 * 00/06/18 eranian Support for stacked physical calls
26 * Note that some of these calls use a static-register only calling
27 * convention which has nothing to do with the regular calling
