    Add linux/cacheflush.h · 522a0032
    Matthew Wilcox (Oracle) authored
    Many architectures do not include asm-generic/cacheflush.h, so turn
    the includes on their head and add linux/cacheflush.h which includes
    asm/cacheflush.h.
    
    Move the flush_dcache_folio() declaration from asm-generic/cacheflush.h
    to linux/cacheflush.h and change linux/highmem.h to include
    linux/cacheflush.h instead of asm/cacheflush.h so that all necessary
    places will see flush_dcache_folio().
    
    More functions should have their default implementations moved in the
    future, but those are for follow-on patches.  This fixes csky, sparc and
    sparc64 which were missed in the commit which added flush_dcache_folio().
