2016-01-09powerpc: Fix build break due to paca mm_context_t changesMichael Ellerman
Commit 2fc251a8dda5 ("powerpc: Copy only required pieces of the mm_context_t to the paca") broke the build for CONFIG_PPC_STD_MMU_64=y and CONFIG_PPC_MM_SLICES=n. That only happens for a kernel built with 4K pages and HUGETLB disabled, which is why we missed it. Fix it by adding a mm_ctx_user_psize member to the paca and populating it in the appropriate places.

2016-01-08selinux: Inode label revalidation performance fixAndreas Gruenbacher
Commit 5d226df4 has introduced a performance regression of about 10% in the UnixBench pipe benchmark. It turns out that the call to inode_security in selinux_file_permission can be moved below the zero-mask test and that inode_security_revalidate can be removed entirely, which brings us back to roughly the original performance.

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.
