Modified files:
sys/sparc64/sparc64 swtch.s vm_machdep.c
sys/sparc64/include pcb.h
Log:
1. Convert the tstate saved in the pcb to a pstate and test for PSTATE_PEF
to determine if a process is using floating point. in order to avoid
sign extending a 13 bit immediate.
2. We don't need to context switch cwp anymore, it is better to just
fiddle the save tstate on return from traps. See exception.s 1.10
and 1.12.
3. Completely remove pcb_cwp.
4. Implement vmapbuf, vunmapbuf and vm_fault_quick. Completely remove
TODOs from vm_machdep.c (yay!).
