OK, so tlb_remove_page_ptdesc() and tl

- In nx_walk_and_build(), use scatterwalk_start_at_pos() instead of a
more complex way to achieve the same result.
- Also in nx_walk_and_build(), use the new functions scatterwalk_next()
which consolidates scatterwalk_clamp() and scatterwalk_map(), and use

p10_aes_gcm_crypt() is abusing the scatter_walk API to get the virtual
address for the first source scatterlist element. But this code is only
built for PPC64 which is a !HIGHMEM platform, and it can read past a
page boundary from the address returned by scatterwalk_map() whic
