From: Mike Rapoport <redacted> for_each_memblock() is used to iterate over memblock.memory in a few places that use data from memblock_region rather than the memory ranges. Introduce separate for_each_mem_region() and for_each_reserved_mem_region() to improve encapsulation of memblock internals from its users.

~~~~~~~~~~~~~~~~~ Wonder why emphasize 'registered' memory. Other than this confusion to me, this patch looks good.
