arm: include asm-generic/memory_model.h from page.h rather than memory.h
Patch series "mm, arch: add generic implementation of pfn_valid() for
FLATMEM", v2.
Every architecture that supports FLATMEM memory model defines its own
version of pfn_valid() that essentially compares a pfn to max_mapnr.
Use mips/powerpc version implemented as static inline as a generic
implementation of pfn_valid() and drop its per-architecture definitions
This patch (of 4):
Makes it consistent with other architectures and allows for generic
definition of pfn_valid() in asm-generic/memory_model.h with clear
override in arch/arm/include/asm/page.h
