scall_64.S: Move to kernel mode and enable intrs properly.
r4k_tlb_glue.S: The fast handlers must work with intrs disabled, since we
can not risk changes in entryhi/lo/tlbregisters. do_page_fault() _must_ work
with intrs enabled, to prevent deadlocks in the intercpu tlbflush code.
andes.c/r4xx0.c: Make tlb register accesses conservatively safe from intrs
coming in and changing register contents.
