x86, memblock: Add memblock_x86_to_bootmem() memblock_x86_to_bootmem() will reserve memblock.reserved.region in bootmem after bootmem is set up. We can use it to with all arches that support memblock later. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: H.

x86, memblock: Add memblock_x86_reserve_range/memblock_x86_free_range They are wrappers for core versions, which take start/end/name instead of base/size. This will make x86 conversion eaasier. could add more debug print out -v2: change get_max_mapped() to memblock.default_alloc_limit according to Michael Ellerman and Ben change to memblock_x86_reserve_range and memblock_x86_free_range according to Michael Ellerman -v3: call check_and_double after reserve/free, so could avoid to use find_memblock_area.
