Hi,
I found some small optimizations while reading the code of memblock.
Please help to review. Thanks.

Peng Zhang (3):
  memblock: Make a boundary tighter in memblock_add_range().
  memblock: Make finding index faster when modify regions.
  memblock: Avoid useless checks in memblock_merge_regions().
