Subject: [PATCH] Drop some headers from mm.h

mm.h doesn't use directly anything from mutex.h and backing-dev.h, so
remove them and add them back to files which need them.

Cross-compile tested on many configs and archs.

BTW, switching to SLUB makes this nice workload to go OOM, which SLAB
never allowed itself, however, I'm not prepared right now to tell the
story. It smells like semi-recent breakage, because, I can swear,
I ran it with SLUB for stress-testing purposes.
