"physmem" in the memblock allocator is somewhat weird: it's not actually used for allocation, it's simply information collected during boot, which describes the unmodified physical memory map at boot time, without any standby/hotplugged memory. It's only used on s390 and is currently the only reason s390 keeps using CONFIG_ARCH_KEEP_MEMBLOCK.
Physmem isn't numa aware and current users don't specify any flags. Let's hide it from the user, exposing only for_each_physmem(), and simplify. The interface for physmem is now really minimalistic: - memblock_physmem_add() to add ranges - for_each_physmem() / __next_physmem_range() to walk physmem ranges
Don't place it into an __init section and don't discard it without CONFIG_ARCH_KEEP_MEMBLOCK. As we're reusing __next_mem_range(), remove the __meminit notifier to avoid section mismatch warnings once CONFIG_ARCH_KEEP_MEMBLOCK is no longer used with CONFIG_HAVE_MEMBLOCK_PHYS_MAP.
While fixing up the documentation, sneak in some related cleanups. We can stop setting CONFIG_ARCH_KEEP_MEMBLOCK for s390 next.
