Weird! Mutt seems to have mangled the patch on me. I must have pressed some
buttons while composing the message. Try it now. Thanks! (Can I resubmit the
patch like this, or does it need to go in its own email? I can't quite tell
from looking at linux-mtd and lkml traffic.)


Remove redundant config checks when the subdirectory's Makefile is already
conditionally processed. Add more conditional processing when the subdirectory
can be selected/deselected as a whole.
