change TK_NOTYET to HAVE_RCONS
change commented-out /* && cn_tab.cn_screen */ to && raster_console()

- The pmap now includes support for ASNs. We no longer need to flush
...
the TLB and I-cache in the SWITCH_CONTEXT macro.
- Right after switching to proc0's newly-created context at startup time,
flush the TLB and I-cache; this is the only place where it's not done
automatically.
- Fix a nasty bug in a critical section of cpu_switch(); change the
pmap_activate -> SWITCH_CONTEXT -> pmap_deactivate sequence to
pmap_deactivate -> pmap_activate -> SWITCH_CONTEXT. This prevents
erroneously marking a pmap inactive if switching to a process that
shares it's address space (and thus its pmap) with the oldproc! Noticed
by Chris Demetriou.

invalidation algorithm:
