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. Suggested by Michael Ellerman
