Compat / compat-wireless / bluetooth for 2.6.33-rc4 and

From: Luis R. Rodriguez

The 2.6.33-rc4 and kernels came out a few days ago, along
with it comes the respective 2.6.33-rc4 [1] and [2]
compat-wireless releases [3]. As noted previously the
compat-wireless-2.6.33 releases now also have bluetooth backported for
kernels >= 2.6.27.

A few release notes:

* compat.git - generic kernel compatibility package. This is
currently used on bleeding edge compat-wireless and the 2.6.33
compat-wireless releases. Other external drivers are welcomed to take
advantage of this though.
- gets pm-qos for kernels down to 2.6.23
- gets the new 2.6.33 firmware_class backported for older kernels
which allows usage of
drivers with thew new request_firmware_nowait(). Users of this for
802.11 right now are ar9170.
This actually goes only compile tested, please let me know if this worked.

* compat-wireless-
- now goes all the way down to 2.6.23 for ath5k and ath9k, should
be easy to test/enable others
- gets pm-qos backport as well

* compat-wireless-2.6.33-rc4:
- The new debugfs_remove_recursive(), added as of 2.6.26 but used
on 802.11 only until
2.6.32-rc4 on both mac80211 and cfg80211 cannot be backported as
it relies on two
static variables on fs/debugfs/inode.c, to enable backporting
for older kernels than
2.6.26 we'll need to relabel CONFIG_CFG80211_DEBUGFS and
and disable them for older kernels.

Due to the new multiqueue patch we only support kernels >= 2.6.27 on
bleeding edge compat-wireless. This patch is due to go into stable
down to 2.6.32 so both next releases and 2.6.32-rc5 are
expected to have this and as such will have backporting disabled for
older kernels as well until we figure out how to properly backport

The compat-wireless release causes this harmless warning on
older kernels < 2.6.24, it can safely be ingored, I see no way of
avoiding it.
