That meant renaming, eg folio_test_multi() to folio_test_large(). - I hadn't included folio wrappers for zero_user_segments(), etc. Also, multi-page^W^W large folio support is now independent of CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need to fall back to the out-of-line zero_user_segments(). - The build bots finally got round to telling me that I missed a couple of architectures when adding flush_dcache_folio(). Christoph suggested that we just add linux/cacheflush.h and not rely on asm-generic/cacheflush.h. These changes have been in linux-next for the last week with no new squawks.
