| | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the hardcoded 255 seconds limit for a real limit based on oscr_freq. Also, the 'firmware_version' field is changed to '1' to allow the user space application to easily detect that this driver supports a higher maximum timeout.

| * | cxgb3: Fix crash caused by stashing wrong netdev_queueRoland Dreier2009-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

| * | ixgbe: Fix coexistence of FCoE and Flow Director in 82599Yi Zou2009-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR) in 82599 and remove the disabling of FDIR when FCoE is enabled. Currently, FDIR is turned off when FCoE is enabled under the assumption that FCoE is always enabled with DCB being turned on. However, FDIR does not have to be turned off all the time when FCoE is enabled since FCoE can be enabled without DCB being turned on, e.g., use link pause only. This patch makes sure that when DCB is turned on or off, FDIR is turned on or off correspondingly; and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

This problem has been reported as Bugzilla #13725. The failure is expressed by the following message in the logs: WARNING: at net/mac80211/tx.c:1325 ieee80211_tx+0x23c/0x298 [mac80211]() Hardware name: HP Pavilion dv2700 Notebook PC tx refused but queue active This problem has been recently observed in the wireless-testing tree, where a full solution is being tested.

| | * | Atheros Kconfig needs to be dependent on WLAN_80211Jay Sternberg2009-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Atheros top level menu needs a "depends WLAN_80211" to properly indent within menuconfig and xconfig interfaces. This is purely a visual issue but it effects all subsequent drivers. The issue is the top level menu does not include a dependency on WLAN_80211 so within the tree structure, Atheros is at the same level as WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with all subsequent drives, so it is really a subordinate.

If the tx queue is drained during channel change, internal reset and etc, the last descriptor may not be the holding descriptor and we fail to reclaim them. This results in the following two issues. 1. Tx stuck - We drop all the frames coming from upper layer due to shortage in tx desc. 2. Crash - If we fail to reclaim a tx descriptor, we miss to update the tx BA window with the seq number of the frame associated to that desc, which, at some point, result in the following crash due to an assert failure in ath_tx_addto_baw(). This patch fixes these two issues. kernel BUG at ../drivers/net/wireless/ath/ath9k/xmit.c:180!

I'm sure we will make other interesting findings. This is step one of fixing the overall locking dependency mess in cpufreq.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b14893a62c73af0eca414cfed505b8c09efc613c although it was very much needed to properly cleanup ondemand timer, opened-up a can of worms related to locking dependencies in cpufreq. Patch here defines the need for dbs_mutex and cleans up its usage in ondemand governor. This also resolves the lockdep warnings reported here http://lkml.indiana.edu/hypermail/linux/kernel/0906.1/01925.html http://lkml.indiana.edu/hypermail/linux/kernel/0907.0/00820.html and few others..

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | When the last device in the dpm list is unregistered directly after its prepare() callback returned with -EAGAIN, the return code is passed to the calling function, resulting in a suspend failure. Prevent this by clearing the return code after -EAGAIN. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After some API change, intel_iommu_unmap_range() introduced a assumption that parameter size != 0, otherwise the dma_pte_clean_range() would have a overflowed argument. But the user like KVM don't have this assumption before, then some BUG() triggered. Fix it by ignoring size = 0.

* | | Free struct device in fw_dev_release()Catalin Marinas2009-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The f_dev in _request_firmware() is allocated via the fw_setup_device() and fw_register_device() calls and its class set to firmware_class (the class release function is fw_dev_release). Commit 6acf70f078ca replaced the kfree(dev) in fw_dev_release() with a put_device() call but my understanding is that the release function is called via put_device -> kobject_put -> kref_put -> koject_release etc. and it should call kfree since it's the last to see this device structure alive. Because of that, the _request_firmware() function on its -ENOENT error path only calls device_unregister(f_dev) which would eventually call fw_dev_release() but there is no kfree (the subsequent put_device call would just make the kref negative).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.
