Dave,

I present to you another round of patches intended for 2.6.29.  There is
a MAINTAINERS patch that recognizes the reality that Michael Wu is no
longer touching mac80211.  There is a power setting patch for rtl8187
that corrects a functional regression, and a NULL pointer fix for
iwlagn.  There are a couple of regulatory-related patches that are
isolated and I think merit inclusion based on their nature.  Finally,
there is an ath5k fix for an older problem that is more prevalent since
the merge of "ath5k: ignore the return value of
ath5k_hw_noise_floor_calibration" and which addresses kernel.org bugs
12068 and 12080.

Please let me know if there are problems!

Thanks,

John
