3.15-stable review patch. If anyone has any objections, please let me know.
------------------ From: Max Filippov <[email protected]> commit be6ae382dc153da51cf066c8dd523aa955f02531 upstream. When sysmem reservation occurs exactly at the end of an existing block that block is deleted, because it is incorrectly included in the range of memblocks to remove. Fix that by skipping such block.
