Merge tag 'folio-5.16b' of git://git.infradead.org/users/willy/pagecache
Pull folio fixes from Matthew Wilcox: "In the course of preparing the folio changes for iomap for next merge window, we discovered some problems that would be nice to address now: - Renaming multi-page folios to large folios. mapping_multi_page_folio_support() is just a little too long, so we settled on mapping_large_folio_support(). That meant renaming, eg folio_test_multi() to folio_test_large(). Rename AS_THP_SUPPORT to match - 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(). Remove FS_THP_SUPPORT to match - 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" * tag 'folio-5.16b' of git://git.infradead.org/users/willy/pagecache: mm: Add functions to zero portions of a folio fs: Rename AS_THP_SUPPORT and mapping_thp_support fs: Remove FS_THP_SUPPORT mm: Remove folio_test_single mm: Rename folio_test_multi to folio_test_large Add linux/cacheflush.h
