None of the rt2x00 PCI devices support 64-bit DMA addresses (they all
only accept 32-bit buffer addresses). Hence it makes no sense to try to
enable 64-bit DMA addresses. Only try to enable 32-bit DMA addresses.

If the RTNL is held when we invoke flush_scheduled_work() we could
deadlock. One such case is linkwatch, it is a work struct which tries
to grab the RTNL semaphore.
The most common case are net driver ->stop() methods. The
simplest conversion is to instead use cancel_{delayed_}work_sync()
explicitly on the various work struct the driver uses.
This is an OK transformation because these work structs are doing
things like resetting the chip, restarting link negotiation, and so
forth. And if we're bringing down the device, we're about to turn the
chip off and reset it anways. So if we cancel a pending work event,
that's fine here.
Some drivers were working around this deadlock by using a msleep()
polling loop of some sort, and those cases are converted to instead
use cancel_{delayed_}work_sync() as well.

This patch fixes a data alignment issue in the zd1211rw driver.

This fixes an issus that made "iwconfig eth1 power on" non-working.
When we get a "PS sleep" event, we have to confirm this to the firmware.
The confirm happens with a command, but this command is special: the
firmware won't send us a response. if_cs_host_to_card() is setting
priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and
was never cleared back.
Now I put the special knowledge that the CMD_802_11_PS_MODE with
CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly
clearing the dnld_sent state in lbs_send_confirmsleep().

When another scan is in progress, a direct scan gets dropped on the
floor. However, that direct scan is usually the scan that's really
needed by userspace, and gets stomped on by all the broadcast scans the
ipw2200 driver issues internally. Make sure the direct scan happens
eventually, and as a bonus ensure that the passive scan worker is
cleaned up when appropriate.
The change of request_passive_scan form a struct work to struct
delayed_work is only to make the set_wx_scan() code a bit simpler, it's
still only used with a delay of 0 to match previous behavior.

If there are no networks on the free list, expire the oldest one when
creating a new adhoc network. Because ipw2200 and the ieee80211 stack
don't actually cull old networks and place them back on the free list
unless they are needed for new probe responses, over time the free list
would become empty and creating an adhoc network would fail due to the !
list_empty(...) check.

This patch saves memory by reducing the size of the entry in the txq. It
was 640 because of the calibration commands. Calibration commands are now
sent as HUGE commands (using the extra 1024 bytes at the end of the command
txq), hence, there is no need for 640 in every entry any more.

This patch solves a bug in debugfs unregistration. iwlwifi registers its
debugfs files under cfg80211's dir, but removed its files only after having
unregistered mac80211 that removes cfg80211 debugfs dir. This garbaged
debugfs and didn't allow to rmmod and insmod iwlwifi several times in a
row.
