2013-08-13stmmac: fix init_dma_desc_rings() to handle errorsBartlomiej Zolnierkiewicz
In stmmac_init_rx_buffers(): * add missing handling of dma_map_single() error * remove superfluous unlikely() optimization while at it Add stmmac_free_rx_buffers() helper and use it in dma_free_rx_skbufs(). In init_dma_desc_rings(): * add missing handling of kmalloc_array() errors * fix handling of dma_alloc_coherent() and stmmac_init_rx_buffers() errors * make function return an error value on error and 0 on success In stmmac_open(): * add handling of init_dma_desc_rings() return value Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: David S.

2013-08-12can: pcan_usb: fix wrong memcpy() bytes lengthStephane Grosjean
Fix possibly wrong memcpy() bytes length since some CAN records received from PCAN-USB could define a DLC field in range [9..15]. In that case, the real DLC value MUST be used to move forward the record pointer but, only 8 bytes max. MUST be copied into the data field of the struct can_frame object of the skb given to the network core.

2013-08-09vxlan: fix a soft lockup in vxlan module removalCong Wang
This is a regression introduced by: commit fe5c3561e6f0ac7c9546209f01351113c1b77ec8 Author: stephen hemminger <stephen@networkplumber.org> Date: Sat Jul 13 10:18:18 2013 -0700 vxlan: add necessary locking on device removal The problem is that vxlan_dellink(), which is called with RTNL lock held, tries to flush the workqueue synchronously, but apparently igmp_join and igmp_leave work need to hold RTNL lock too, therefore we have a soft lockup! As suggested by Stephen, probably the flush_workqueue can just be removed and let the normal refcounting work. The workqueue has a reference to device and socket, therefore the cleanups should work correctly.

The idea is to make the interface future-proof so we can add flags and not new fields. However, flags value isn't validated, as a result, userspace can't detect which flags are supported.

Fix from Colin Cross addresses this by adding a process flag to mark the hibernate/suspend process to inform the freezer that that process should be ignored. - One of the recent cpufreq reverts uncovered a problem in the core causing the cpufreq driver module refcount to become negative after a system suspend-resume cycle. Fix from Rafael J Wysocki. - The evaluation of the ACPI battery _BIX method has never worked correctly, because the commit that added support for it forgot to take the "Revision" field in the return package into account.

2013-08-01PCI: mvebu: Disable prefetchable memory support in PCI-to-PCI bridgeThomas Petazzoni
The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able to dynamically set up MBus address decoding windows for PCI I/O and memory regions depending on the PCI devices enumerated by Linux. However, this emulated PCI-to-PCI bridge logic makes the Linux PCI core believe that prefetchable memory regions are supported (because the registers are read/write), while in fact no adress decoding window is ever created for such regions. Since the Marvell MBus address decoding windows do not distinguish memory regions and prefetchable memory regions, this patch takes a simple approach: change the PCI-to-PCI bridge emulation to let the Linux PCI core know that we don't support prefetchable memory regions. To achieve this, we simply make the prefetchable memory base a read-only register that always returns 0. Reading/writing all the other prefetchable memory related registers has no effect. This problem was originally reported by Finn Hoffmann <finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem was that the PCI-to-PCI bridge emulation was making the Linux PCI core believe that we support prefetchable memory, so the Linux PCI core was only filling the prefetchable memory base and limit registers, which does not lead to a MBus window being created. The below patch has been confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has otherwise been successfully tested on the Armada XP GP platform with a e1000e PCIe NIC and a Marvell SATA PCIe card.

2013-08-01powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31)Aaro Koskinen
slots-fan on G5 Xserve is always running at full speed with windfarm_rm31 driver, resulting in a very high acoustic noise level. It seems the fan parameters are incorrect, and have been copied from the Drive Bay fan (RPM, not present on rm31) of the legacy therm_pm72 driver. This patch changes the parameters to match the Slots fan (PWM) of therm_pm72. With the patch, slots-fan speed drops from 99% to 19% during normal use, and slots-temp settle to ~42'C.
