ia64: switch to NO_BOOTMEM
Since ia64 already uses memblock to register available physical memory it is only required to move the calls to register_active_ranges() that wrap memblock_add_node() earlier and replace bootmem memory reservations with memblock_reserve(). Of course, all the code that find the place to put the bootmem bitmap is removed. Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
