- Write the first of 3 shared trap prolog macros. Does not fully support V86 entry and DR saving yet. Used by all KiTraps (except double-fault for now) and KiDebugService.
- Update asm.h with more stuff from ks386.inc. - Use only documented constants in syscall.S through asm.h. svn path=/trunk/; revision=20921
