v2 removes the krb5 patch and changes the code so that nth_page is
only called if HIGHMEM is enabled.  Also switch to from page_address
to lowmem_page_address.

This patch series is based on top of:

https://patchwork.kernel.org/project/linux-crypto/patch/20250310172016.153423-1-ebiggers@kernel.org/

Curiously, the Crypto API scatterwalk incremented pages by hand
rather than using nth_page.  Possibly because scatterwalk predates
nth_page (the following commit is from the history tree):

            [CRYPTO]: in/out scatterlist support for ciphers.

Fix this by using nth_page.
