Memory management in generic is highly architecture specific, but on NOMMU architectures, it is mostly trivial, so just add a default implementation in asm-generic that applies to all NOMMU architectures. The two files cache.h and cacheflush.h can possibly also be used by architectures that have an MMU but never require flushing the cache or have cache lines larger than 32 bytes.
