John David Anglin 7139bc1579 [PARISC] Purge existing TLB entries in set_pte_at and ptep_set_wrprotect
This patch goes a long way toward fixing the minifail bug, and
it  significantly improves the stability of SMP machines such as
the rp3440.  When write  protecting a page for COW, we need to
purge the existing translation.  Otherwise, the COW break
doesn't occur as expected because the TLB may still have a stale entry
which allows writes.
