- handle the supervisor bit from SR correctly on iframes
- various notes on 060 vs others:
- 060 has 040 compatible mmu, except pgtables must *not* be on copyback memory
- 060 has a processor control reg which has a revision number to use in system_info
- notes on ctx switch:
- must be kept in sync with asm code
- fsave generate variable size frames, so reserve space and use non-predecrementing EA.
