powerpc/fsl-booke: Fix problem with _tlbil_va being interrupted
...
An example calling sequence which we did see:
copy_user_highpage -> kmap_atomic -> flush_tlb_page -> _tlbil_va
We got interrupted after setting up the MAS registers before the
tlbwe and the interrupt handler that caused the interrupt also did
a kmap_atomic (ide code) and thus on returning from the interrupt
the MAS registers no longer contained the proper values.
Since we dont save/restore MAS registers for normal interrupts we
need to disable interrupts in _tlbil_va to ensure atomicity.
