Public bug reported:
On MIPS, data accesses to pages mapped in the TLB result in
mips_cpu_handle_mmu_fault() marking the page unconditionally executable,
even if the TLB entry has the XI bit set. Later on, when there is an
attempt to execute this page, no exception is generated, even though
TLBXI is expected.
