2640d7c0b8 AHCI: Remove an unnecessary flush from ahci_qc_issue
In an I/O heavy workload (IOZone), ahci_qc_issue is the second-highest
consumer of CPU cycles.  Removing the flush gets us approximately 10%
bandwidth improvement.  I believe this to be because the CPU can start
queueing the next request instead of waiting for the readl() to flush the
writes to the device.  The flush isn't necessary because we're using a
'queue' metaphor; we don't guarantee the command has got to the device,
nor do we need to guarantee the command has got to the controller.

24920c8a63 AHCI: speed up resume
During resume, sleep 1 second to wait for the HBA reset
to finish is a waste of time.

According to the AHCI 1.2 spec,
We should poll the HOST_CTL register,
and return error if the host reset is not
finished within 1 second.

Test results show that the HBA reset can be done quickly(in usecs).
And this patch may save nearly 1 second during resume.

87fbc5a060 libata: improve EH internal command timeout handling
ATA_TMOUT_INTERNAL which was 30secs were used for all internal
commands which is way too long when something goes wrong.  This patch
implements command type based stepped timeouts.  Different command
types can use different timeouts and each command type can use
different timeout values after timeouts.

ie. the initial timeout is set to a value which should cover most of
the cases but not too long so that run away cases don't delay things
too much.  After the first try times out, the second try can use
longer timeout and if that one times out too, it can go for full 30sec
timeout.

IDENTIFYs use 5s - 10s - 30s timeout and all other commands use 5s -
10s timeouts.

This patch significantly cuts down the needed time to handle failure
cases while still allowing libata to work with nut job devices through
retries.

0a2c0f5615 libata: improve EH retry delay handling
EH retries were delayed by 5 seconds to ensure that resets don't occur
back-to-back.  However, this 5 second delay is superflous or excessive
in many cases.  For example, after IDENTIFY times out, there's no
reason to wait five more seconds before retrying.

This patch adds ehc->last_reset timestamp and record the timestamp for
the last reset trial or success and uses it to space resets by
ATA_EH_RESET_COOL_DOWN which is 5 secs and removes unconditional 5 sec
sleeps.

As this change makes inter-try waits often shorter and they're
redundant in nature, this patch also removes the "retrying..."
messages.

While at it, convert explicit rounding up division to DIV_ROUND_UP().

This change speeds up EH in many cases w/o sacrificing robustness.

341c2c958e libata: consistently use msecs for time durations
libata has been using mix of jiffies and msecs for time druations.
This is getting confusing.  As writing sub HZ values in jiffies is
PITA and msecs_to_jiffies() can't be used as initializer, unify unit
for all time durations to msecs.  So, durations are in msecs and
deadlines are in jiffies.  ata_deadline() is added to compute deadline
from a start time and duration in msecs.

While at it, drop now superflous _msec suffix from arguments and
rename @timeout to @deadline if it represents a fixed point in time
rather than duration.

f434b2d111 mac80211: fix struct ieee80211_tx_queue_params
Multiple issues:
 - there are no "default" values needed
 - cw_min/cw_max can be larger than documented
 - restructure to decrease size
 - use get_unaligned_le16

f591fa5dbb mac80211: fix TX sequence numbers
This patch makes mac80211 assign proper sequence numbers to
QoS-data frames. It also removes the old sequence number code
because we noticed that only the driver or hardware can assign
sequence numbers to non-QoS-data and especially management
frames in a race-free manner because beacons aren't passed
through mac80211's TX path.

This patch also adds temporary code to the rt2x00 drivers to
not break them completely, that code will have to be reworked
for proper sequence numbers on beacons.

It also moves sequence number assignment down in the TX path
so no sequence numbers are assigned to frames that are dropped.

22bb1be4d2 wext: make sysfs bits optional and deprecate them
The /sys/class/net/*/wireless/ direcory is, as far as I know, not
used by anyone. Additionally, the same data is available via wext
ioctls. Hence the sysfs files are pretty much useless. This patch
makes them optional and schedules them for removal.

2560b6e2e4 mac80211: Fix ieee80211_rx_reorder_ampdu: ignore QoS null packets
This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu.
This check has been broken by 'mac80211: rx.c use new helpers'.

Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in
RX.

4ece16a1cf rtl8187: use different ANAPARAM*_OFF values for 8187B
For RTL8187B it seems we need special values too for ANAPARAM*_OFF
values (and not use RTL8187 ones). The ANAPARAM*_OFF values used are the
stock ones read from the hardware after a cold boot.

bd88a7812f rt2x00: Reorganize beacon handling
With the new beacon handling from mac80211 we can
reorganize the beacon handling in rt2x00 as well.
This patch will move the function to the TX handlers,
and move all duplicate code into rt2x00queue.c.

After this change the descriptor helper functions
from rt2x00queue.c no longer need to be exported
outside of rt2x00lib and can be declared static.

9d139c810a mac80211: revamp beacon configuration
This patch changes mac80211's beacon configuration handling
to never pass skbs to the driver directly but rather always
require the driver to use ieee80211_beacon_get(). Additionally,
it introduces "change flags" on the config_interface() call
to enable drivers to figure out what is changing. Finally, it
removes the beacon_update() driver callback in favour of
having IBSS beacon delivered by ieee80211_beacon_get() as well.
