asm-generic/cacheflush.h: flush icache when copying to user pages
The copy_to_user_page() function is supposed to flush the icache on the
memory that was written, but the current asm-generic version lacks that
logic. While normally it isn't a big deal as the asm-generic version of
icache flushing is a stub, it is a deal for ports that want to use the
asm-generic version as a baseline and then overlay its own specific parts
(like icache flushing).
