orinoco: Provide option to avoid unnecessary fw caching
Make firmware caching on startup optional, and make it default.
When the option is not selected and PM_SLEEP is configured, then
cache firmware in the suspend pm_notifier. This configuration saves
about 64k RAM in normal use, but can lead to a situation where the
driver is configured to use a different firmware.

ath9k: Handle -ENOMEM on RX gracefully
We would get an oops on RX on -ENOMEM by passing
NULL to the hardware on ath_rx_buf_link(). The oops
would look something like this:
ath_rx_tasklet+0x515/0x53b
ath9k_tasklet+0x48
tasklet_action
__do_softirq
irq_exit
do_IRQ
RIP: ath_rx_buf_link+0x3a
We correct this by handling the requeue directly on
the ath_rx_tasklet() and trying to allocate an skb
*prior* to sending up the last hardware processed
skb. If we run out of memory this gauranteees we have
skbs to work with while it simply drops new received

rfkill: always call get_state() hook on resume
We "optimize" away the get_state() hook call on rfkill_toggle_radio
when doing a forced state change. This means the resume path is not
calling get_state() as it should.
Call it manually on the resume handler, as we don't want to mess with
the EPO path by removing the optimization. This has the added benefit
of making it explicit that rfkill->state could have been modified
before we hit the rfkill_toggle_radio() call in the class resume
handler.

rfkill: preserve state across suspend
The rfkill class API requires that the driver connected to a class
call rfkill_force_state() on resume to update the real state of the
rfkill controller, OR that it provides a get_state() hook.
This means there is potentially a hidden call in the resume code flow
that changes rfkill->state (i.e. rfkill_force_state()), so the
previous state of the transmitter was being lost.
The simplest and most future-proof way to fix this is to explicitly
store the pre-sleep state on the rfkill structure, and restore from
that on resume.

When rt2x00queue_get_queue() returns NULL in the TX
path, it means mac80211 has passed us an invalid queue,
although this should be impossible, it shouldn't hurt
if we send mac80211 a signal to stop the queue either.
Both issues can simply be resolved by removing their
manual failure handler and making them use the failure path
provided in rt2x00mac_tx().

rt2x00: Move rt73usb register access wrappers into rt2x00usb
rt2500usb and rt73usb have different register word sizes,
for that reason the register access wrappers were never
moved into rt2x00usb.
With rt2800usb on its way, we should favor the 32bit
register access and move those wrappers into rt2x00usb.
That saves duplicate code, since only rt2500usb will
need the special 16bit wrappers.

rt2x00: Cleanup indirect register access
All code which accessed indirect registers was similar
in respect to the for-loop, the given timeout, etc.
Move it into a seperate function, which for PCI drivers
can be moved into rt2x00pci.
This allows us to cleanup the cleanup the code further
by removing the goto statementsand making the codepath
look a bit nicer.

tcp: handle shift/merge of cloned skbs too
This caused me to get repeatably:
tcpdump: pcap_loop: recvfrom: Bad address
Happens occassionally when I tcpdump my for-looped test xfers:
while [ : ]; do echo -n "$(date '+%s.%N') "; ./sendfile; sleep 20; done
Rest of the relevant commands:
ethtool -K eth0 tso off
tc qdisc add dev eth0 root netem drop 4%
tcpdump -n -s0 -i eth0 -w sacklog.all
Running net-next under kvm, connection goes to the same host
(basically just out of kvm). The connection itself works ok
and data gets sent without corruption even with a large
number of tests while tcpdump fails usually within less than
5 tests.
Whether it only happens because of this change or not, I
don't know for sure but it's the only thing with which
I've seen that error. The non-cloned variant works w/o it
for much longer time. I'm yet to debug where the error
actually comes from.
