I am =FCber-surprised to hear that FC10 2.6.27 kernels have added
pci_ioremap_bar() in their kernel header include/linux/pci.h. I
have verified this by checking:

http://download.fedora.redhat.com/pub/fedora/linux/updates/10/x86_64/ke=
rnel-devel-2.6.27.9-159.fc10.x86_64.rpm

I have checked upstrea 2.6.27.9 and even 2.6.27.12 and they do not have=
 this. This breaks
compatibility projects like compat-wireless :(

Good point, hopefully this is enough of an argument to make the patch
go into 2.6.27. The patch is already in for >=3D 2.6.28.

Greg -- there is an annoying message that gets printed very often
when new Atheros 11n cards are used, this is printed upon hw reset
which occurs on channel changes (scans) and as such happens quite
often. The message was moved to print only when "EEPROM debugging"
was enaabled through upstream commit f1dc56003b23d2d5bb5a756de6b1633a76=
c9e697.
Unfortunately this commit is pretty large as it refactored hw.c into
separate files. Below is a small one line patch that changes this. Plea=
se
let me know if this is OK for 2.6.27.x

Subject: [PATCH] ath9k: quiet harmless ForceXPAon messages

This is a port of one line of upstream patch
f1dc56003b23d2d5bb5a756de6b1633a76c9e697

The "ForceXPAon" messages on ath9k were not meant to be printed
regularly, lets quiet them as this can happen quite frequently
(scans) and will fill the logs with tons of these messages.
