| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using RX_COPY_THRESHOLD is incorrect if the SKB is actually smaller than that. We have already accounted for this in NETFRONT_SKB_CB(skb)->pull_to so use that instead. Fixes WARN_ON from skb_try_coalesce.

| | * ath9k: Fix Kconfig for ATH9K_HTCVladimir Kondratiev2013-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC. Both uses common Atheros code from ath.ko and need ATH_COMMON. However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not. As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with unresolved symbols. This patch moves ATH_COMMON selection to the common part for both ATH9K and ATH9K_HTC Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

| | * carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESHChristian Lamparter2013-01-021-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.

This may lead to problems when there are two devices such that the .suspend() callback executed for one of them depends on runtime PM working for the other. In that case, if runtime PM has already been disabled for the second device, the first one's .suspend() won't work correctly (and analogously for resume). To make those issues go away, make the PM core disable runtime PM for devices right before executing subsystem/driver .suspend_late() callbacks for them and enable runtime PM for them right after executing subsystem/driver .resume_early() callbacks for them. This way the potential conflitcs between .suspend_late()/.resume_early() and their runtime PM counterparts are still prevented from happening, but the subtle ordering issues related to disabling/enabling runtime PM for devices during system suspend/resume are much easier to avoid.

As drivers/cpufreq/cpufreq_governor.c contains no MODULE directives, the resulting module has no license specified, which results in logging of a "module license 'unspecified' taints kernel". In addition, a number of globals are exported GPL only, and are therefore not available. This fix establishes a new boolean configuration variable that forces cpufreq_governor.o to be linked into the kernel whenever either cpufreq_ondemand or cpufreq_conservative is selected.

This leads to a contention problem with a large number of CPUs, because they all try to run the idle routine at the same time. The lock can be safely removed because of how is used the cpuidle API. Namely, cpuidle_register_driver() is called first, but the cpuidle idle function is not entered before cpuidle_register_device() is called, because the cpuidle device is not enabled then. Moreover, cpuidle_unregister_driver(), which would reset the driver value to NULL, is not called before cpuidle_unregister_device(). All of the cpuidle drivers use the API in the same way. In general, a cleanup around the lock is necessary and a proper refcounting mechanism should be used to ensure the consistency in the API (for example, cpuidle_unregister_driver() should fail if the driver's refcount is not 0). However, these modifications will require some code reorganization and rewrite which will be too intrusive for a fix. For this reason, fix the contention problem introduced by commit bf4d1b5 by simply removing the locking from cpuidle_get_cpu_driver(), which restores the original behavior of that routine.
