ARM: 6166/1: Proper prefetch abort handling on pre-ARMv6

Browse source

commit 5e27fb78df upstream.

Instruction faults on pre-ARMv6 CPUs are interpreted as
a 'translation fault', but do_translation_fault doesn't
handle well if user mode trying to run instruction above
TASK_SIZE, and result in the infinite retry of that
instruction.
