Title:
mips_cpu_handle_mmu_fault renders all accessed pages executable
Status in QEMU:
New
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.
