2011-08-09rt2x00: Fix PCI interrupt processing race on SMP systemsHelmut Schaa
When toggle_irq is called for PCI devices to disable device interrupts it used tasklet_disable to wait for a possibly running tasklet to finish. However, on SMP systems the tasklet might still be scheduled on another CPU. Instead, use tasklet_kill to ensure that all scheduled tasklets are finished before returning from toggle_irq. Furthermore, it was possible that a tasklet reenabled its interrupt even though interrupts have been disabled already. Fix this by checking the DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts during tasklet processing. While at it also enable/kill the TBTT and PRETBTT tasklets in the toggle_irq callback and only use tasklet_kill in stop_queue to wait for a currently scheduled beacon update before returning.

2011-08-09rtlwifi: Eliminate raw reads and writes from PCIe portionLarry Finger
The PCIe driver used raw reads and writes on the PCIe hardware. As all of these are only affecting the configuration space, all of then can be converted to pci_{read,write}_config_XX calls.

2011-08-09ath9k: Use atomic reference count for interrupt opsRajkumar Manoharan
Let us enable/disable interrupts based on reference count. By doing this we can ensure that interrupts are never be enabled in the middle of tasklet processing. Instead of addressing corner cases like "ath9k: avoid enabling interrupts while processing rx", this approach handles it in generic manner.

2011-08-09ath9k_hw: Fix incorrect spur_freq_sd for AR9003Rajkumar Manoharan
Spur frequency was incorrectly computed with 10Mhz offset which could cause the filter would not notch out the spur and also this could improve rx sensitivity in HT40.

2011-08-09ath9k: do not enable interrupt on set interrupt maskRajkumar Manoharan
At preset set_interrupt also enables interrupt after changing mask. This is not necessary in all cases and also sometime it breaks the assumption that interrupt was disabled. So let us enable the interrupt explicity if it was disabled earlier. This could also avoid unnecessary register ops and also helps the follow up patch to have global ref count for interrupts ops.

2011-08-09libertas: disable functionality when interface is downDaniel Drake
Modify the driver so that it does not function when the interface is down, in preparation for runtime power management. No commands can be run while the interface is down, so the ndo_dev_stop routine now directly does all necessary work (including asking the device to disconnect from the network and disabling multicast functionality) directly. power_save and power_restore hooks are added meaning that card drivers can take steps to turn the device off when the interface is down. The MAC address can now only be changed when all interfaces are down; the new address will be programmed when an interface gets brought up. This matches mac80211 behaviour. Also, some small cleanups/simplifications were made in the surrounding device handling logic. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-08-08ath9k_hw: calculate a much better approximation of channel noiseFelix Fietkau
Currently ath9k presents the internal calibrated noise floor as channel noise measurement, however this results in highly chip specific values that are only useful as relative measurements but do not resemble any real channel noise values. In order to give a much better approximation of the real channel noise, add the difference between the measured noise floor and the nominal chip specific noise floor to the default minimum channel noise value, which is currently used to calculate the signal strength from the RSSI value. This may not be 100% accurate, but it's much better than what's there before. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-08-08iwlagn: bump firmware API for some devicesJohannes Berg
We're working on improvements for the firmware for some devices, and need to bump the API for those since they won't be backward compatible completely (the earlier patch reserving queue 10 for P2P).

2011-08-08iwlagn: separate firmware version warningJohannes Berg
We sometimes need to support new firmware API for a while before we can publish them since testing them fully takes a long time. We could keep all the new code private, but that causes plenty of problems and sometimes we can give a pre-release version of firmware to people who need to test. However, when we just bump the API version, the driver will warn everybody that their firmware is outdated, when in fact it isn't. (Currently our case for this doesn't really change the API but bumping the API version is necessary because the firmware isn't fully backward compatible) In order to handle this in the future, add a new "api_ok" version; only below this will the driver warn that the uCode is too old.

2011-08-08iwlagn: reserve queue 10 for TX during scan dwellJohannes Berg
New uCode images will use queue 10 for TX during scan (for P2P offchannel operation scan). We'll bump the API version of those, but before we need to reserve queue 10 and stop using it for aggregation. To simplify the code, always reserve it, we could continue using it on older uCode images but that'd be rather complicated. Also, we'll set it up to map to the right FIFO as needed later, but as we don't use the queue now that doesn't hurt.
