Seems like this was just due to local "mm: Rename pmd_read_atomic()"
conflict after merging Linus's tree (which introduced another
pmd_read_atomic() callsite). Peter already seems to have rebased and
made the fix - thanks Peter.

Yep, just needed a fixup. Patch applied but didn't build. Arguably I
should've compiled before pushing, but meh :-)
