2012-04-25acerhdf: lowered default temp fanon/fanoff valuesPeter Feuerer
Due to new supported hardware, of which the actual temperature limits of processor, harddisk and other components are unknown, it feels safer with lower fanon / fanoff settings. It won't change much for most people, already using acerhdf, as they use their own fanon/fanoff variable settings when loading the module. Furthermore seems like kernel and userspace tools have been improved to work more efficient and netbooks don't get so hot anymore.

When RSS is enabled, interrupt vector 0 does not receive any rx traffic. The rx producer index fields for vector 0's status block should be considered reserved in this case.

2012-04-24e1000e: Fix default interrupt throttle rate not set in NIC HWJeff Kirsher
Based on the original patch from Ying Cai <ycai@google.com> This change ensures that the itr/itr_setting adjustment logic is used, even for the default/compiled-in value. Context: When we changed the default InterruptThrottleRate value from default (3 = dynamic mode) to 8000 for example, only adapter->itr_setting (which controls interrupt coalescing mode) was set to 8000, but adapter->itr (which controls the value set in NIC register) was not updated accordingly. So from ethtool, it seemed the interrupt throttling is enabled at 8000 intr/s, but the NIC actually was running in dynamic mode which has lower CPU efficiency especially when throughput is not high.

2012-04-24USB: EHCI: fix crash during suspend on ASUS computersAlan Stern
This patch (as1545) fixes a problem affecting several ASUS computers: The machine crashes or corrupts memory when going into suspend if the ehci-hcd driver is bound to any controllers. Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. This fixes Bugzilla #42728.

2012-04-24iwlwifi: fix hardware queue programmingJohannes Berg
Newer devices have 20 (5000 series) or 30 (6000 series) hardware queues, rather than the 16 that 4965 had. This was added to the driver a long time ago, but improperly: the queue registers for the higher queues aren't just continuations of the registers for the first 16 queues, they are in other places. Therefore, the hardware would lock up when trying to activate queue 16 or above and the device would have to be restarted. Thanks goes to Emmanuel who identified this and told me how the queue programming should be done. Note that we don't use queues 20 and higher today and doing so needs more work than this.

2012-04-24md: fix possible corruption of array metadata on shutdown.NeilBrown
commit c744a65c1e2d59acc54333ce8 md: don't set md arrays to readonly on shutdown. removed the possibility of a 'BUG' when data is written to an array that has just been switched to read-only, but also introduced the possibility that the array metadata could be corrupted. If, when md_notify_reboot gets the mddev lock, the array is in a state where it is assembled but hasn't been started (as can happen if the personality module is not available, or in other unusual situations), then incorrect metadata will be written out making it impossible to re-assemble the array. So only call __md_stop_writes() if the array has actually been activated. This patch is needed for any stable kernel which has had the above commit applied.

2012-04-24md: don't call ->add_disk unless there is good reason.NeilBrown
Commit 7bfec5f35c68121e7b18 md/raid5: If there is a spare and a want_replacement device, start replacement. cause md_check_recovery to call ->add_disk much more often. Instead of only when the array is degraded, it is now called whenever md_check_recovery finds anything useful to do, which includes updating the metadata for clean<->dirty transition. This causes unnecessary work, and causes info messages from ->add_disk to be reported much too often. So refine md_check_recovery to only do any actual recovery checking (including ->add_disk) if MD_RECOVERY_NEEDED is set. This fix is suitable for 3.3.y: Cc: stable@vger.kernel.org Reported-by: Jan Ceuleers <jan.ceuleers@computer.org> Signed-off-by: NeilBrown <neilb@suse.de>

2012-04-23ACPI: Convert wake_sleep_flags to a value instead of functionKonrad Rzeszutek Wilk
With commit a2ef5c4fd44ce3922435139393b89f2cce47f576 "ACPI: Move module parameter gts and bfs to sleep.c" the wake_sleep_flags is required when calling acpi_enter_sleep_state, which means that if there are functions outside the sleep.c code they can't get the wake_sleep_flags values.

2012-04-23ipw2200: Fix race condition in the command completion acknowledgeStanislav Yakovlev
Driver incorrectly validates command completion: instead of waiting for a command to be acknowledged it continues execution. Most of the time driver gets acknowledge of the command completion in a tasklet before it executes the next one. But sometimes it sends the next command before it gets acknowledge for the previous one. In such a case one of the following error messages appear in the log: Failed to send SYSTEM_CONFIG: Already sending a command. Failed to send ASSOCIATE: Already sending a command. Failed to send TX_POWER: Already sending a command. After that you need to reload the driver to get it working again. This bug occurs during roaming (reported by Sam Varshavchik) https://bugzilla.redhat.com/show_bug.cgi?id=738508 and machine booting (reported by Tom Gundersen and Mads Kiilerich) https://bugs.archlinux.org/task/28097 https://bugzilla.redhat.com/show_bug.cgi?id=802106 This patch doesn't fix the delay issue during firmware load.

2012-04-23ath9k: fix tx power settings for AR9287Gabor Juhos
The 'ath9k_hw_update_regulatory_maxpower' helper function has been introduced by commit a55f858852e4345d0a31af593c46738ca8614bff (ath9k_hw: Cleanup TX power calculation for AR9287). Updating of the max_power_level value has been moved into the helper function in that change, however the removed code from 'ath9k_hw_ar9287_set_txpower' has not been replaced with a call of the new helper function. Due to that missing call, retrieving tx power for 2x2 and 3x3 chainmask is not handled properly. During the calculation of the tx power for 2x2 and 3x3 chainmasks the values are reduced. Those reductions must be compensated during retrieving. Fix this by adding the missing call of the helper function.

2012-04-23ath9k: add an extra boolean parameter to ath9k_hw_apply_txpowerGabor Juhos
In order to unifying regulatory limit handling commit ca2c68cc7bc80fc4504fb420df04cce99c9ee6ec (ath9k_hw: clean up tx power handling) introduced a new helper function 'ath9k_hw_apply_txpower', and the direct calls of 'ah->eep_ops->set_txpower' has been replaced by a call of the helper function. This caused a change in the behaviour of the 'ath9k_hw_set_txpowerlimit' function. The purpose of that function is to calculate and store the rate txpower table and the regulatory limit without touching the hardware registers. Before the commit, the 'test' parameter of the function was passed to the 'ah->eep_ops->set_txpower'. Now the calling of the 'set_txpower' function happens indirectly through 'ath9k_hw_apply_txpower', so the 'test' argument of the 'set_txpower' is always 'false'. This patch restores the original behaviour of 'ath9k_hw_set_txpowerlimit' by adding a new argument to 'ath9k_hw_apply_txpower.'
