From: Dan Carpenter <[email protected]>
Smatch complains that these should probably be bitwise ORs instead of
logical. It doesn't matter for "prox" but it makes a difference for
"strip1" and "strip2".
NOTE: This patch was backported earlier, but only as far back as 2.6.38.
To make backporting the next few patches easier, we complete this backport
all the way to 2.6.30.
