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 | |
