Move the default (no-op) implementation of flush_icache_pages() to
<linux/cacheflush.h> from <asm-generic/cacheflush.h>. Remove the
flush_icache_page() wrapper from each architecture into
<linux/cacheflush.h>.

Current best practice is to reuse the name of the function as a define to
indicate that the function is implemented by the architecture.

cacheflush.h: Add forward declaration for struct folio2022-03-23T17:11:03+00:00Herbert Xuherbert@gondor.apana.org.au2022-03-23T03:35:10+00:00urn:sha1:30d024b5058e0433914022f87d917a97a9527632
The struct folio is not declared in cacheflush.h so we need to provide
a forward declaration as otherwise users of this header file may get
warnings.

Add linux/cacheflush.h2021-11-17T15:36:15+00:00Matthew Wilcox (Oracle)willy@infradead.org2021-11-06T21:13:35+00:00urn:sha1:522a0032af005502507f5f81ae64fdcc82b5d068
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().
