ath9k: use ieee80211_conf on ath9k_hw_iscal_supported()
ath9k_hw_iscal_supported() just needs to be aware of your band
and if HT20 is being used so lets abandon our internal channel,
HT appended values and internal mode values and use ieee80211_conf
which already carries this information. This works as calibration
is being done for the currently configured channel.

HW reset calls pass the same variables or structs
which we can obtain easily from ah. Although this also applies
during channel changes as we will keep around the ath9k_channel
passed as an argument for now.
We now also now propagate the hw reset errors down.

We don't need to use our own mode for setting the
the routine tries to do, in fact lets remove ath_chan2mode() now as
we can simply use the currently set band and the HT configuration
provided by mac80211 through the ieee80211_conf. This works on
changing channels as well as the internal ath9k_channel we use is
based on the ieee80211_channel in the config.

- CMD_SIZE, CMD_HUGE, CMD_SKB duplication removal.
- iwl3945_queue replacement in order to also get rid of the duplicated

Improve error message reporting when a frame was received
with unknown rate. Instead of using the boolean check if
the frame is supposed to be a PLCP value or not, we should
add a new mask (RXDONE_SIGNAL_MASK) which returns the type
identification for a signal value (i.e. PLCP). At the moment
we only have 2 different types, but more will arrive when
support for 11n is added.

Restrict drivers to only access link_qual structure during
link tuning. The contents of these fields are for the drivers
and all fields are allowed to be changed to values the driver

This means that some fields need to be moved outside of this
structure to restrict access only to rt2x00link itself.
This allows some code to be moved outside of the rt2x00.h header
and into rt2x00link.c.

The link_tuner() function will always call bbp_read()
at the start of the function. Because this is an

to it (especially for USB hardware).
We already store the value read from the register
into the vgc_level value inside the link structure.
Instead of reading from the register we can read that
field directly and base the tuner on that value.
This reduces the time the registers are locked with
the csr_mutex and speeds up the link_tuner processing.

firewire: sbp2: add workarounds for 2nd and 3rd generation iPods
According to https://bugs.launchpad.net/bugs/294391
- 3rd generation iPods need the "fix capacity" workaround after all
(apparently they crash after the last sector was accessed),
- 2nd generation iPods need the "128 kB maximum request size"
workaround.
Alas both iPod generations feature the same model ID in the config ROM,
hence we can only define a shared quirks list entry for them. Luckily
the fix capacity workaround did not show a negative effect in Jarod's
tests with 2nd gen. iPod.
A side note: Apple computers in target mode (or at least an x86 Mac
mini) don't have firmware_version and model_id, hence none of the iPod
quirks list entries is active for them.

ARM: OMAP: gptimer min_delta_ns corrected
When 32 kHz timer is used the min_delta_ns should be initialized so
that it reflects the timer programming cost. A write to the timer
device will be usually posted, but it takes roughly 3 cycles before
it is effective. If the timer is reprogrammed before that, the CPU
will stall until the previous write completes. This was pointed out by
Richard Woodruff.
Since the lower bound for min_delta_ns is 1000, the change is visible
only with tick rates less than 3 MHz.
Also note that the old value is incorrect for 32 kHz also due to
a rounding error, and it can cause the timer queue to hang (due to
clockevent code trying to program the timer with zero ticks).
