git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2016-01-08 This series contains updates to ixgbe only. Vasu provides three fixes for ixgbe, first assigns a minimum credit to a traffic class to resolve a Tx hang for CEE mode configuration. Second fix changes the driver to use netdev->fcoe_ddp_xid instead of our local IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices and avoids a DDP skip error on X550. Lastly fix the PFC configuration to include X550 devices. Emil provides a fix for reporting the speed in ethtool by using the stored value in out adapter structure. This is due to external drivers may end up with unknown speed when calling ethtool_get_settings(). Mark fixes the handling of any outer UDP checksum, by passing the skb up with CHECKSUM_NONE when an outer UDP checksum is set. This will cause the stack to check the checksum, also do not increment an error counter because we do not really know if there is an actual error. Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being performed on such packets. Fix this by skipping extended headers when they are present. Usha fixes an issue with X550 and getting FDMI HBA attributes when FCoE support is enabled. Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which the hardware generates MDD events. Resolve this by setting the expected values in the transmit context descriptors for FCoE/FIP frames and adding a flush after writing the RDLEN register. ==================== Signed-off-by: David S.

2016-01-08x86/mm: Micro-optimise clflush_cache_range()Chris Wilson
Whilst inspecting the asm for clflush_cache_range() and some perf profiles that required extensive flushing of single cachelines (from part of the intel-gpu-tools GPU benchmarks), we noticed that gcc was reloading boot_cpu_data.x86_clflush_size on every iteration of the loop. We can manually hoist that read which perf regarded as taking ~25% of the function time for a single cacheline flush.

Mitch adds a useful error message and return value when the VFs are being reset, since there is a brief window of time when the VF cannot be configured because they do not have a VSI to configure. Also made a driver change to allow the user to specify a zero MAC address for VFs, which causes the existing MAC address to be removed and allows the VF to use a random address (like libvirt). Sowmini Varadhan from Oracle adds similar functionality/fix to i40e that was added to ixgbe earlier. The fix attempts to look up the MAC address in the Open Firmware on systems that support it and use IDPROM on SPARC if no OF address is found. Anjali provides a fix the code path so that we do not call skb_set_hash() if the feature is disabled.

2016-01-08libata: skip debounce delay on link resumeDanesh Petigara
The link resume logic uses a 200msec delay while debouncing the SControl register. The rationale behind that delay is to accommodate some PHYs that behave badly if their SStatus/ SControl registers are pounded immediately on resume. The Broadcom STB SATA PHY does not seem to have this issue. This patch introduces a new link flag that allows platforms to skip the debounce delay if it isn't needed.

2016-01-08Merge tag 'omap-for-v4.4/onenand-corruption' of ↵Arnd Bergmann
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Pull "urgent onenand file system corruption fix for n900" from Tony Lindgren: Last minute urgent pull request to prevent file system corruption on Nokia N900. Looks like we have a GPMC bus timing bug that has gone unnoticed because of bootloader configured registers until few days ago. We are not detecting the onenand clock rate properly unless we have CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption that can be easily be reproduced. There seems to be also an additional bug still lurking around for onenand corruption. But that is still being investigated and it does not seem to be GPMC timings related. Meanwhile, it would be good to get this fix into v4.4 to prevent wrong timings from corrupting onenand. * tag 'omap-for-v4.4/onenand-corruption' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruption

2016-01-08locks: prink more detail when there are leaked locksJeff Layton
Right now, we just get WARN_ON_ONCE, which is not particularly helpful. Have it dump some info about the locks and the inode to make it easier to track down leaked locks in the future. Signed-off-by: Jeff Layton <jeff.layton@primarydata.com> Acked-by: "J. Bruce Fields" <bfields@fieldses.org>
