Commit e00c8cc9 "x86: Use new cache mode type in memtype related functions" broke the ARCH=um build. arch/x86/include/asm/cacheflush.h:67:36: error: return type is an incomplete type static inline enum page_cache_mode get_page_memtype(struct page *pg) The reason is simple. get_page_memtype() and set_page_memtype() require enum page_cache_mode now, which is defined in asm/pgtable_types.h. UM does not include that file for obvious reasons. The simple solution is to move that functions to arch/x86/mm/pat.c where the only callsites of this are located. They should have been there in the first place.
