Subject: Please pull 'fixes-jgarzik' branch of wireless-2.6 (for 2.6.23)

Jeff,

One of these is a fairly obvious one-liner (COMPATIBLE_IOCTL).  The other is
a bit more complicated, but fixes a problem created by a patch already
in 2.6.23 (reported this week by Yoshifuji).  Please pull this for
2.6.23 if at all possible.

Thanks!

John
