2013-10-02net: mv643xx_eth: fix missing device_node for port devicesSebastian Hesselbarth
DT-based mv643xx_eth probes and creates platform_devices for the port devices on its own. To allow fixups for ports based on the device_node, we need to set .of_node of the corresponding device with the correct node.

2013-10-02net: mv643xx_eth: fix orphaned statistics timer crashSebastian Hesselbarth
The periodic statistics timer gets started at port _probe() time, but is stopped on _stop() only. In a modular environment, this can cause the timer to access already deallocated memory, if the module is unloaded without starting the eth device. To fix this, we add the timer right before the port is started, instead of at _probe() time.

2013-10-02net: mv643xx_eth: update statistics timer from timer context onlySebastian Hesselbarth
Each port driver installs a periodic timer to update port statistics by calling mib_counters_update. As mib_counters_update is also called from non-timer context, we should not reschedule the timer there but rather move it to timer-only context.

2013-10-02igb: Avoid uninitialized advertised variable in eee_set_curAndi Kleen
eee_get_cur assumes that the output data is already zeroed. It can read-modify-write the advertised field: if (ipcnfg & E1000_IPCNFG_EEE_100M_AN) 2594 edata->advertised |= ADVERTISED_100baseT_Full; This is ok for the normal ethtool eee_get call, which always zeroes the input data before. But eee_set_cur also calls eee_get_cur and it did not zero the input field. Later on it then compares agsinst the field, which can contain partial stack garbage. Zero the input field in eee_set_cur() too.

2013-10-02net: calxedaxgmac: determine number of address filters at runtimeRob Herring
Highbank and Midway xgmac h/w have different number of MAC address filter registers with 7 and 31, respectively. Highbank has been wrong, so fix it and detect the number of filter registers at run-time. Unfortunately, the version register is the same on both SOCs, so simply test if write to the last filter register will take a value. It always reads as 0 if not.

In commit 2ee68f621af280 (net: calxedaxgmac: fix various errors in xgmac_set_rx_mode), a fix to clean-up old address entries was added. However, the loop to zero out the entries failed to increment the register address resulting in only 1 entry getting cleared. Fix this to correctly use the loop index. Also, the end of the loop condition was off by 1 and should have been <= rather than <. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-10-01ll_temac: Reset dma descriptors indexes on ndo_openRicardo Ribalda
The dma descriptors indexes are only initialized on the probe function. If a packet is on the buffer when temac_stop is called, the dma descriptors indexes can be left on a incorrect state where no other package can be sent. So an interface could be left in an usable state after ifdow/ifup. This patch makes sure that the descriptors indexes are in a proper status when the device is open.

2013-10-01powerpc/83xx: gianfar_ptp: select 1588 clock source through dts fileAida Mynzhasova
Currently IEEE 1588 timer reference clock source is determined through hard-coded value in gianfar_ptp driver. This patch allows to select ptp clock source by means of device tree file node. For instance: fsl,cksel = <0>; for using external (TSEC_TMR_CLK input) high precision timer reference clock. Other acceptable values: <1> : eTSEC system clock <2> : eTSEC1 transmit clock <3> : RTC clock input When this attribute isn't used, eTSEC system clock will serve as IEEE 1588 timer reference clock.

2013-10-01bonding: Fix broken promiscuity reference counting issueNeil Horman
Recently grabbed this report: https://bugzilla.redhat.com/show_bug.cgi?id=1005567 Of an issue in which the bonding driver, with an attached vlan encountered the following errors when bond0 was taken down and back up: dummy1: promiscuity touches roof, set promiscuity failed. promiscuity feature of device might be broken. The error occurs because, during __bond_release_one, if we release our last slave, we take on a random mac address and issue a NETDEV_CHANGEADDR notification. With an attached vlan, the vlan may see that the vlan and bond mac address were in sync, but no longer are. This triggers a call to dev_uc_add and dev_set_rx_mode, which enables IFF_PROMISC on the bond device. Then, when we complete __bond_release_one, we use the current state of the bond flags to determine if we should decrement the promiscuity of the releasing slave. But since the bond changed promiscuity state during the release operation, we incorrectly decrement the slave promisc count when it wasn't in promiscuous mode to begin with, causing the above error Fix is pretty simple, just cache the bonding flags at the start of the function and use those when determining the need to set promiscuity. This is also needed for the ALLMULTI flag CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: Mark Wu <wudxw@linux.vnet.ibm.com> CC: "David S.

2013-09-30ath9k: fix powersave response handling for BA session packetsFelix Fietkau
When a packet is passed from mac80211 to the driver with the IEEE80211_TX_CTL_PS_RESPONSE flag set, it bypasses the normal driver internal queueing and goes directly to the UAPSD queue. When that happens, packets that are part of a BlockAck session still need to be tracked as such inside the driver, otherwise it will create discrepancies in the receiver BA reorder window, causing traffic stalls. This only happens in AP mode with powersave-enabled clients.

2013-09-30mwifiex: fix SDIO interrupt lost issueAmitkumar Karwar
601216e "mwifiex: process RX packets in SDIO IRQ thread directly" introduced a command timeout issue which can be reproduced easily on an AM33xx platform using a test application written by Daniel Mack: https://gist.github.com/zonque/6579314 mwifiex_main_process() is called from both the SDIO handler and the workqueue. In case an interrupt occurs right after the int_status check, but before updating the mwifiex_processing flag, this interrupt gets lost, resulting in a command timeout and consequently a card reset. Let main_proc_lock protect both int_status and mwifiex_processing flag. This fixes the interrupt lost issue.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These fix one recent cpufreq regression, a few older bugs that may harm users and a kerneldoc typo. Specifics: 1) After the recent locking changes in the cpufreq core it is possible to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if cpufreq_get() is called before registering a cpufreq driver. Fix from Viresh Kumar. 2) If intel_pstate has been loaded already, it doesn't make sense to do anything in acpi_cpufreq_init() and moreover doing something in there in that case may be harmful, so make that function return immediately if another cpufreq driver is already present. From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock. From Lv Zheng. 4) A NULL pointer may be dereferenced by the exynos5440 cpufreq driver if a memory allocation made by it fails. Fix from Sachin Kamat. 5) Hanjun Guo's commit fixes a typo in the kerneldoc comment documenting acpi_bus_unregister_driver()" * tag 'pm+acpi-3.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: fix typo in comments of acpi_bus_unregister_driver() cpufreq: exynos5440: Fix potential NULL pointer dereference cpufreq: check cpufreq driver is valid and cpufreq isn't disabled in cpufreq_get() acpi-cpufreq: skip loading acpi_cpufreq after intel_pstate ACPI / IPMI: Fix atomic context requirement of ipmi_msg_handler()
2013-09-28PCI: Workaround missing pci_set_master in pci driversYinghai Lu
Ben Herrenschmidt found that commit 928bea964827 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.

2013-09-28USBNET: fix handling padding packetMing Lei
Commit 638c5115a7949(USBNET: support DMA SG) introduces DMA SG if the usb host controller is capable of building packet from discontinuous buffers, but missed handling padding packet when building DMA SG. This patch attachs the pre-allocated padding packet at the end of the sg list, so padding packet can be sent to device if drivers require that.
