ARM: Add support for checking access permissions on prefetch aborts
ARMv6 introduces non-executable mappings, which can cause prefetch aborts
when an attempt is made to execute from such a mapping. Currently, this
causes us to loop in the page fault handler since we don't correctly
check for proper permissions.
Fix this by checking that VMAs have VM_EXEC set for prefetch aborts.
