Instead of using the out-of-line EWMA calculation, use DECLARE_EWMA() to create static inlines.

Since commit feb44f1f7a4ac299d1ab1c3606860e70b9b89d69 (x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need a full APIC driver and thus should depend on X86_LOCAL_APIC.

2015-08-19ALSA: usb-audio: Fix runtime PM unbalanceTakashi Iwai
The fix for deadlock in PM in commit [1ee23fe07ee8: ALSA: usb-audio: Fix deadlocks at resuming] introduced a new check of in_pm flag. However, the brainless patch author evaluated it in a wrong way (logical AND instead of logical OR), thus usb_autopm_get_interface() is wrongly called at probing, leading to unbalance of runtime PM refcount. This patch fixes it by correcting the logic.

2015-08-19netfilter: nft_payload: work around vlan header strippingFlorian Westphal
make payload expression aware of the fact that VLAN offload may have removed a vlan header. When we encounter tagged skb, transparently insert the tag into the register so that vlan header matching can work without userspace being aware of offload features.

2015-08-18target: Fix handling of small allocation lengths in REPORT LUNSRoland Dreier
REPORT LUNS should not fail just because the allocation length is less than 16. The relevant section of SPC-4 is: 4.2.5.6 Allocation length The ALLOCATION LENGTH field specifies the maximum number of bytes or blocks that an application client has allocated in the Data-In Buffer. The ALLOCATION LENGTH field specifies bytes unless a different requirement is stated in the command definition. An allocation length of zero specifies that no data shall be transferred. This condition shall not be considered an error. So we should just truncate our response rather than return an error.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-08-18 This series contains updates to igb, e100, e1000e and ixgbe. Shota Suzuki provides a fix for a possible overflow in igb_set_interrupt_capability() which leads to an oops. When changing the number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same manner as when initializing the igb driver. Vasily Averin provides a fix for a missing rtnl_unlock() for when we error out due to not being able to allocate memory for our queues. Stefan Assman provides a couple of fixes for igb/igbvf. First changes the igb driver in probe to simply call igb_enable_sriov() instead of igb_sriov_reinit() since we are starting from scratch. Then in igbvf, fix the driver where it does not clear the buffer_info->dma in all cases after calling dma_unmap_single(), which was found by changing the MTU twice. Richard Cochran implements the periodic output function using the programmable clock outputs available in i210 when possible, falling back to the target time for longer periods. Todd adds support for the Marvell PHY 1512 which is required for i354 devices. Then updates igb to make sure SR-IOV init uses the correct number of queues, since recent changes could result in the PF holding onto all of the queues. Alex Williamson provides a fix in the case where a guest OS does not support hot-unplug, so disable SR-IOV prior to unregister_netdev() to avoid the problem. Jia-Ju Bai provides several patches, first knocks some collecting dust off an old e100 driver to add a check to avoid a null pointer dereference. Then cleans up a possible resource leak by releasing the skb buffer allocated when the e100_xmit_prepare() runs into an issue in the DMA mapping. In igb, add a missing rtnl_unlock() for when we error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme(). Provides a e1000e fix, based on suggestions from Alex Duyck to move head/tail register writing to e1000_configure_tx/rx() to avoid a possible null pointer dereference (similar to igb driver). Lastly, fix a possible memory leak in igb_probe(), where the memory shadow_vfta allocated by kcalloc in igb_sw_init() is not freed. Mark simplifies port-specific macros for ixgbe by eliminating explicit comparisons with 0 and enclose formal parameters in parens to eliminate the risk of an operator precedence issue. ==================== Signed-off-by: David S.

We can drop the check because if vrf_ptr is present then we must have the vrf device as a master and since we're running with rtnl it can't go away. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-18lwtunnel: ip tunnel: fix multiple routes with different encapJiri Benc
Currently, two routes going through the same tunnel interface are considered the same even when they are routed to a different host after encapsulation. This causes all routes added after the first one to have incorrect encapsulation parameters. This is nicely visible by doing: # ip r a 192.168.1.2/32 dev vxlan0 tunnel dst 10.0.0.2 # ip r a 192.168.1.3/32 dev vxlan0 tunnel dst 10.0.0.3 # ip r [...] 192.168.1.2/32 tunnel id 0 src 0.0.0.0 dst 10.0.0.2 [...] 192.168.1.3/32 tunnel id 0 src 0.0.0.0 dst 10.0.0.2 [...] Implement the missing comparison function.
