Modified files:
sys/sparc64/include pcb.h tlb.h
sys/sparc64/sparc64 genassym.c support.S trap.c
Log:
Demark sections of code that need special fault handling with labels.
Check if the trapped pc is inside of the demarked sections to implement
fault recovery for copyin etc, instead of pcb_onfault. Handle recovery
from data access exceptions as well as page faults.
