	drivers: convert shrinkers to new count/scan API

does not contain lowmem_shrink(), but lowmem_scan() instead. plus at lest
one more patch on top of it (e2bfaf75e763396b7baa7c1effa4053d7f19e6d3):

[..]
-static int lowmem_shrink(struct shrinker *s, struct shrink_control *sc)

+static long lowmem_scan(struct shrinker *s, struct shrink_control *sc)
[..]

wouldn't it be better to have the patch against -next in this case (in
case it fixes anything)?

thanks,
	-ss
