Log message:
"Implement fast path TLB miss handling. Walk the page table without
creating a trapframe, with exceptions disabled and using only BANK1
registers. If a valid pte is found, load it and return. Otherwise
create a trapframe and proceed to the full-blown C handler."
from u...@netbsd, ok miod@
speed-ups measured by miod@ and me were between 44% and 50%...
