    mm/memory_hotplug: rename walk_memory_range() and pass start+size instead of pfns · fbcf73ce
    David Hildenbrand authored
    walk_memory_range() was once used to iterate over sections.  Now, it
    iterates over memory blocks.  Rename the function, fixup the
    Also, pass start+size instead of PFNs, which is what most callers
    already have at hand.  (we'll rework link_mem_sections() most probably
    Follow-up patches will rework, simplify, and move walk_memory_blocks()
    to drivers/base/memory.c.
    Note: walk_memory_blocks() only works correctly right now if the
    start_pfn is aligned to a section start.  This is the case right now,
    but we'll generalize the function in a follow up patch so the semantics
    match the documentation.
