3.2.73-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: NeilBrown <[email protected]> commit 66eefe5de11db1e0d8f2edc3880d50e7c36a9d43 upstream. Calling e.g. blk_queue_max_hw_sectors() after calls to disk_stack_limits() discards the settings determined by disk_stack_limits(). So we need to make those calls first. Fixes: 199dc6ed5179 ("md/raid0: update queue parameter in a safer location.")
