Thanks Mike. With the additional diff below, I can get it to build with and without the p4d clean-up patches in -next. If Anshuman confirms that they work, I can add them on top of the arm64 for-next/memory-hotremove branch
Can't I simply fold these into the offending -mm arm-arm64-add-support-for-folded-p4d-page-tables.patch?
