Subject: linux-next: manual merge of the wireless-next tree with the
 net-next tree

Hi John,

Today's linux-next merge of the wireless-next tree got a conflict in
drivers/net/wireless/b43legacy/dma.c between commit 3db1cd5c05f3 ("net:
fix assignment of 0/1 to bool variables") from the net-next tree and
commit 5d07a3d62f63 ("b43legacy: Avoid packet losses in the dma worker
code") from the wireless-next tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
