exec/exec-all.h is for the TCG accelerator's runtime.  NotDirtyInfo and
notdirty_write_{prepare,complete} _might_ belong in there (they sit in
the middle between exec/exec-all.h and memory-internal.h), but
memory_region_access_valid certainly doesn't because it's used with KVM
as well.

In fact, memory_region_access_valid might as well be in memory.h.
