memblock: Use memblock_reserve() in memblock internal functions
Make memblock_double_array(), __memblock_alloc_base() and memblock_alloc_nid() use memblock_reserve() instead of calling memblock_add_region() with reserved array directly. This eases debugging and updates to memblock_add_region(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Yinghai Lu <yinghai@kernel.org>
