    mm/hugetlb: Allow arch to override and call the weak function · e24a1307

    When running in guest mode ppc64 supports a different mechanism for hugetlb
    allocation/reservation. The LPAR management application called HMC can
    be used to reserve a set of hugepages and we pass the details of
    reserved pages via device tree to the guest. (more details in
    htab_dt_scan_hugepage_blocks()) . We do the memblock_reserve of the range
    and later in the boot sequence, we add the reserved range to huge_boot_pages.
    But to enable 16G hugetlb on baremetal config (when we are not running as guest)
    we want to do memblock reservation during boot. Generic code already does this
