    Subject[PATCH v2 17/23] mm/page_cgroup: Use memblock apis for early memory allocations
    Date
    From: Grygorii Strashko <grygorii.strashko@ti.com>

    Switch to memblock interfaces for early memory allocator instead of
    bootmem allocator. No functional change in beahvior than what it is
    in current code from bootmem users points of view.

    Archs already converted to NO_BOOTMEM now directly use memblock
    interfaces instead of bootmem wrappers build on top of memblock. And the
    archs which still uses bootmem, these new apis just fallback to exiting
    bootmem APIs.
