In summary, we need 3 patches but the one fixing __TLBI_RANGE_NUM needs to be
PATCH[1/3] so that it can be easily picked by stable kernel. PATCH[2/3] would
be to improve __TLBI_VADDR_RANGE with masks. PATCH[3/3] will allow __flush_tlb_range_nosync()
to do range-based TLB flush for MAX_TLBI_RANGE_PAGES.

That's about it indeed.


Thanks Marc. v3 was posted for further review.
