Subject[PATCH v11 1/3] arm: arm64: introduce CONFIG_HAVE_MEMBLOCK_PFN_VALID
Date
Make CONFIG_HAVE_MEMBLOCK_PFN_VALID a new config option so it can move
memblock_next_valid_pfn to generic code file. All the latter optimizations
are based on this config.

The memblock initialization time on arm/arm64 can benefit from this.
