Subject: [PATCH] mm/memblock: move memblock_{add,reserve}_region into memblock_{add,reserve}

From: 0xAX <kuleshovmail@...il.com>

The memblock_add_region() and memblock_reserve_region do not nothing specific
before the call of the memblock_add_range(), only print debug output.

We can do the same in the memblock_add() and memblock_reserve() since both
memblock_add_region() and memblock_reserve_region are not used by anybody
outside of memblock.c and the memblock_{add,reserve}() have the same set of
flags and nids.

Since the memblock_add_region() and memblock_reserve_region() anyway will be
inlined, there will not be functional changes, but will improve code readability
a little.
