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.

2016-01-08perf evlist: Make perf_evlist__open() open evsels with their cpus and ↵Adrian Hunter
threads (like perf record does) 'perf record' uses perf_evsel__open() to open events and passes the evsel->cpus and evsel->threads. Many tests and some tools instead use perf_evlist__open() which passes instead evlist->cpus and evlist->threads. Make perf_evlist__open() follow the 'perf record' behaviour so that a consistent approach is taken.

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.
