Title:
  mips_cpu_handle_mmu_fault renders all accessed pages executable

Status in QEMU:
  In Progress

Bug description:
  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.
