I would like to follow the ia64 SAL spec (http://download.intel.com/design/itanium/specupdt/245359.pdf). There is no corresponding Intel spec for x86_64. For examples of what I would like, see the ia64 files: include/asm-ia64/sal.h, include/asm-ia64/sn/sn_sal.h, and arch/ia64/kernel/sal.c. -- Russ Anderson, OS RAS/Partitioning Project Lead SGI - Silicon Graphics Inc rja@sgi.com
