asm-generic: add generic NOMMU versions of some headers 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.

asm-generic/mmu.h: Add support for FDPIC No-MMU architectures often have support for FDPIC binaries. FDPIC support requires two additional fields in the mm_context_t struct. This patch adds these fields to the generic mm_context_t definition if support for FDPIC binaries is enabled. This allows to use the generic mmu.h for a few more architectures.
