Flesh out the sparc64 port considerably. This contains: - mostly complete kernel pmap support, and tested but currently turned off userland pmap support - low level assembly language trap, context switching and support code - fully implemented atomic.h and supporting cpufunc.h - some support for kernel debugging with ddb - various header tweaks and filling out of machine dependent structures 2001-07-31 06:05:05 +00:00			`/*-`
