2015-04-09PCI: layerscape: Simplify platform_get_resource_byname() failure checkingBjorn Helgaas
devm_ioremap_resource() validates the resource it receives, so if we check for devm_ioremap_resource() failure, we need not check for failure of the preceding platform_get_resource(). Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2015-04-09PCI: Don't clear ASPM bits when the FADT declares it's unsupportedMatthew Garrett
Communications with a hardware vendor confirm that the expected behaviour on systems that set the FADT ASPM disable bit but which still grant full PCIe control is for the OS to leave any BIOS configuration intact and refuse to touch the ASPM bits. This mimics the behaviour of Windows. Signed-off-by: Matthew Garrett <mjg59@coreos.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2015-04-09udptunnels: Call handle_offloads after inserting vlan tag.Jesse Gross
handle_offloads() calls skb_reset_inner_headers() to store the layer pointers to the encapsulated packet. However, we currently push the vlag tag (if there is one) onto the packet afterwards. This changes the MAC header for the encapsulated packet but it is not reflected in skb->inner_mac_header, which breaks GSO and drivers which attempt to use this for encapsulation offloads.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree. They are: * nf_tables set timeout infrastructure from Patrick Mchardy. 1) Add support for set timeout support. 2) Add support for set element timeouts using the new set extension infrastructure. 4) Add garbage collection helper functions to get rid of stale elements. Elements are accumulated in a batch that are asynchronously released via RCU when the batch is full. 5) Add garbage collection synchronization helpers. This introduces a new element busy bit to address concurrent access from the netlink API and the garbage collector. 5) Add timeout support for the nft_hash set implementation. The garbage collector peridically checks for stale elements from the workqueue. * iptables/nftables cgroup fixes: 6) Ignore non full-socket objects from the input path, otherwise cgroup match may crash, from Daniel Borkmann. 7) Fix cgroup in nf_tables. 8) Save some cycles from xt_socket by skipping packet header parsing when skb->sk is already set because of early demux. Also from Daniel. * br_netfilter updates from Florian Westphal. 9) Save frag_max_size and restore it from the forward path too. 10) Use a per-cpu area to restore the original source MAC address when traffic is DNAT'ed. 11) Add helper functions to access physical devices. 12) Use these new physdev helper function from xt_physdev. 13) Add another nf_bridge_info_get() helper function to fetch the br_netfilter state information. 14) Annotate original layer 2 protocol number in nf_bridge info, instead of using kludgy flags. 15) Also annotate the pkttype mangling when the packet travels back and forth from the IP to the bridge layer, instead of using a flag. * More nf_tables set enhancement from Patrick: 16) Fix possible usage of set variant that doesn't support timeouts. 17) Avoid spurious "set is full" errors from Netlink API when there are pending stale elements scheduled to be released. 18) Restrict loop checks to set maps. 19) Add support for dynamic set updates from the packet path. 20) Add support to store optional user data (eg. comments) per set element. BTW, I have also pulled net-next into nf-next to anticipate the conflict resolution between your okfn() signature changes and Florian's br_netfilter updates. ==================== Signed-off-by: David S.

Alexander Duyck says: ==================== Replace wmb()/rmb() with dma_wmb()/dma_rmb() where appropriate, round 2 More cleanup of drivers in order to start making use of dma_rmb and dma_wmb calls. This is another pass of what I would consider to be low hanging fruit. There may be other opportunities to make use of the barriers in the Mellanox and Chelsio drivers but I didn't want to risk meddling with code I was not completely familiar with so I am leaving that for future work. I have revisited the Mellanox driver changes. This time around I went only for the sections with a clearly defined pattern. For dma_wmb I used it between accesses of the descriptor bits followed by owner or size. For dma_rmb I used it to replace rmb following a read of the ownership bit in the descriptor. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-04-09mlx4/mlx5: Use dma_wmb/rmb where appropriateAlexander Duyck
This patch should help to improve the performance of the mlx4 and mlx5 on a number of architectures. For example, on x86 the dma_wmb/rmb equates out to a barrer() call as the architecture is already strong ordered, and on PowerPC the call works out to a lwsync which is significantly less expensive than the sync call that was being used for wmb. I placed the new barriers between any spots that seemed to be trying to order memory/memory reads or writes, if there are any spots that involved MMIO I left the existing wmb in place as the new barriers cannot order transactions between coherent and non-coherent memories. v2: Reduced the replacments to just the spots where I could clearly identify the usage pattern.

2015-04-09ASoC: Don't try to register debugfs entries if the parent does not existLars-Peter Clausen
If the registration of a debugfs directory fails this is treated as a non-fatal error in ASoC and operation continues as normal. This means we need to be careful and check if the parent debugfs directory exists if we try to register a debugfs file or sub-directory.
