make elv_register() output atomic
Booting 2.6.21-rc3-g45592145 I noticed the following on one of my
machines in the bootlog:
io scheduler noop registered<6>Time: jiffies clocksource has been installed.
io scheduler deadline registered (default)
Looking at block/elevator.c, it appears that elv_register() uses two
consecutive printks in a non-atomic way, leading to the above glitch. The
attached trivial patch fixes this issue, by using a single printk.
