   631	 * usable memory. But during crashkernel boot only memory specifically
   632	 * reserved for crash scenario is mapped. memblock_add() forces the table to be

   635	 * Align the range to the nearest page boarders. Ranges smaller than page size
   636	 * are not going to be mapped.
   637	 *
   638	 * memblock_reserve() makes sure that future allocations will not touch the
   639	 * table.
