Larry Finger 430cd47fa9 b43: Fix for another Bluetooth Coexistence SPROM Programming error for BCM4306
In trying to help users on the Ubuntu Bugzilla, I discovered another
BCM4306 with the Bluetooth Coexistence programming error in the SPROM.

This patch is contingent on the one that added the Linksys device with
subdevice code of 0x0014.

Johannes Berg 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.

Bruno Randolf 566bfe5a8b mac80211: use hardware flags for signal/noise units
trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.

this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.

for signal:

  IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
  IEEE80211_HW_SIGNAL_DB     - dB difference to unspecified reference point
  IEEE80211_HW_SIGNAL_DBM    - dBm, difference to 1mW

for noise we currently only have dBm:

  IEEE80211_HW_NOISE_DBM     - dBm, difference to 1mW

if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.

i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

Michael Buesch f5eda47f45 b43: Rewrite LO calibration algorithm
This patch distributes the Local Oscillator calibration bursts over time,
so that calibration only happens when it's actually needed.
Currently we periodically perform a recalibration of the whole table.
The table is huge and this takes lots of time. Additionally only small bits
of the table are actually needed at a given time. So instead of maintaining
a huge table with all possible calibration values, we create dynamic calibration
settings that
a) We only calibrate when they are actually needed.
b) Are cached for some time until they expire.
So a recalibration might happen if we need a calibration setting that's not
cached, or if the active calibration setting expires.
Currently the expire timeout is set to 30 seconds. We may raise that in future.

This patch reduces overall memory consumption by nuking the
huge static calibration tables.

This patch has been tested on several 4306, 4311 and 4318 flavours.

Rafael J. Wysocki b844eba292 PM: Remove destroy_suspended_device()
After 2.6.24 there was a plan to make the PM core acquire all device
semaphores during a suspend/hibernation to protect itself from
concurrent operations involving device objects.  That proved to be
too heavy-handed and we found a better way to achieve the goal, but
before it happened, we had introduced the functions
device_pm_schedule_removal() and destroy_suspended_device() to allow
drivers to "safely" destroy a suspended device and we had adapted some
drivers to use them.  Now that these functions are no longer necessary,
it seems reasonable to remove them and modify their users to use the
normal device unregistration instead.

Michael Buesch ba380013b6 b43: Add fastpath to b43_mac_suspend()
This adds a fastpath for the common workloads to the
MAC suspend flushing.
In common workloads the FIFO flush will take between 100 and
200 microseconds. So we want to avoid calling msleep() in the
common case, as it will waste over 800 microseconds + scheduler
overhead.

This fastpath will hit in workloads where only small chunks
of data are transmitted (downloading a file) or when a TX rate bigger
or equal to 24MBit/s is used when transmitting lots of stuff (iperf).
So in the commonly used workloads it will basically always hit.

In case the fastpath is not hit, there's no real performance or latency
disadvantage from that.

And yes, I measured this. So this is not one of these
bad Programmer Likeliness Assumptions that are always wrong. ;)

Michael Buesch 8cf6a31e8d b43: use b43_is_mode() call
We must use the b43_is_mode() call to check the current interface
operation mode.

Michael Buesch 5042c5070d b43: Fix PHY TX control words in SHM
This fixes the initialization of the PHY TX control words in
shared memory. These control words are used for management frames
like beacons.

Michael Buesch c97a4ccc1f b43: Fix beacon BH update
This fixes beacon updating in the bottomhalf.
In case the device is busy, we will defer to later in the IRQ handler.

Michael Buesch a82d992261 b43: Beaconing fixes
These are some beaconing related fixes. Basically it prevents
the card from triggering the beacon IRQ over and over again.

Michael Buesch 7b58416397 b43: Add more N-PHY stuff
This adds some minor stuff for N-PHY support. Nothing special.
Adds Analog switching and some TODOs for RSSI processing.
Just a patch I had floating around for quite some time now.

Michael Buesch 5100d5ac81 b43: Add PIO support for PCMCIA devices
This adds PIO support back (D'oh!) for PCMCIA devices.
This is a complete rewrite of the old PIO code. It does actually work
and we get reasonable performance out of it on a modern machine.
On a PowerBook G4 I get a few MBit for TX and a few more for RX.
So it doesn't work as well as DMA (of course), but it's a _lot_ faster
than the old PIO code (only got a few kBit with that).

The limiting factor is the host CPU speed. So it will generate 100%
CPU usage when the network interface is heavily loaded. A voluntary preemption
point in the RX path makes sure Desktop Latency isn't hurt.

PIO is needed for 16bit PCMCIA devices, as we really don't want to poke with
the braindead DMA mechanisms on PCMCIA sockets. Additionally, not all
PCMCIA sockets do actually support DMA in 16bit mode (mine doesn't).

Michael Buesch 7a193a5df7 b43: Remove irqs_disabled() sanity checks
Remove all irqs_disabled() sanity checks, as they are not safe on
a RT-enabled kernel and will trigger bogus warnings.
