Modified files:
sys/ia64/ia64 pmap.c
sys/ia64/include pmap.h
Log:
Don't use the tpa instruction to implement pmap_kextract. The tpa
instruction requires that a translation is present in the TC. This
may trigger a TLB miss and a subsequent call to vm_fault().
This implementation is deliberately non-inline for debugging and
profiling purposes. Partial or full inlining should eventually be
done.
