Commit 2c09c666 authored by Martin Schwidefsky's avatar Martin Schwidefsky Committed by Linus Torvalds

[PATCH] s390: warnings.

Warning fixes: remove an unused variable and make bitops complain if the
pointer isn't of type long. Make 31 bit BUG() emit 4 0-bytes instead of 2.
This improves the readability of the listing.
