  • Pull kbuild updates from Michal Marek:

    - EXPORT_SYMBOL for asm source by Al Viro.

    This does bring a regression, because genksyms no longer generates
    checksums for these symbols (CONFIG_MODVERSIONS). Nick Piggin is
    working on a patch to fix this.

    Plus, we are talking about functions like strcpy(), which rarely
    change prototypes.

    - Fixes for PPC fallout of the above by Stephen Rothwell and Nick
    Piggin

    - fixdep speedup by Alexey Dobriyan.

    - preparatory work by Nick Piggin to allow architectures to build with
    -ffunction-sections, -fdata-sections and --gc-sections

  • Pull rdma qedr RoCE driver from Doug Ledford:
    "Early on in the merge window I mentioned I had a backlog of new
    drivers waiting to be reviewed and that, in addition to the hns-roce
    driver, I wanted to get possible a couple more reviewed. I ended up
    only having the time to complete one of the additional drivers.

    During Dave Miller's pull request this go around, there were a series
    of 9 patches to the QLogic qed net driver that add basic support for a
    paired RoCE driver. That support is currently not functional because
    it is missing the matching RoCE driver in the RDMA subsystem. I
    managed to finish that review. However, because it goes against part
    of Dave's net pull, and a part that was accepted a day or two after
    the merge window opened, to apply cleanly it has to be applied to
    either the tip of Dave's net branch, or as I did in this case, I just
    applied it to your master after you had taken Dave's pull request."

  • Pull more rdma updates from Doug Ledford:
    "This merge window was the first where Huawei had to try and coordinate
    their patches between their net driver and their new roce driver
    (similar to mlx4 and mlx5).

    They didn't do horribly, but there were some issues (and we knew that
    because they simply didn't know what to do in the beginning). As a
    result, I had a set of patches that depended on some patches that
    normally would have come to you via Dave's tree. Those patches have
    been on netdev@ for a while, so I got Dave to give me his approval to
    send them to you. As such, the other 29 patches I had behind them are
    also now ready to go.

    This catches the hns and hns-roce drivers up to current, and for
    future patches we are working with them to get them up to speed on how
    to do joint driver development so that they don't have these sorts of
    cross tree dependency issues again. BTW, Dave gave me permission to
    add his Acked-by: to the patches against the net tree, but I've had
    this branch through 0day (but not linux-next since it was off by
    itself) and I didn't want to rebase the series just to add Dave's ack
    for the 8 patches in the net area.

    Updates to the hns drivers:

    - Small patch set for hns net driver that the roce patches depend on

    - Various fixes to the hns-roce driver

    - Add connection manager support to the hns-roce driver"

    Specifics:

    - Fix the KERN_CONT usage in acpi_os_vprintf() that has become

    - Fix the fan status checking in the ACPI fan driver to avoid

    - Fix the ACPI Processor Aggregator driver (PAD) to always let the
    special processor_aggregator driver from Xen take over when running
    as Xen dom0 (Juergen Gross).

    - Update the handling of reference device properties in ACPI by

  • Pull more power management updates from Rafael Wysocki:
    "This includes a couple of fixes for cpufreq regressions introduced in

    (that took some time to test) plus a fix and a couple of cleanups in
    that driver, a CPPC cpufreq driver fix, and a some devfreq fixes and
    cleanups (core and exynos-nocp).

    Specifics:

    - Fix two cpufreq regressions causing undesirable changes in behavior
    to appear (one in the core and one in the conservative governor)
    introduced during the 4.8 cycle (Aaro Koskinen, Rafael Wysocki).

    - Fix the way the intel_pstate driver accesses MSRs related to the
    hardware-managed P-states (HWP) feature during the initialization
    which currently is unsafe and may cause the processor to generate a
    general protection fault (Srinivas Pandruvada).

    - Rework the intel_pstate's P-state selection algorithm used on Atom
    processors to avoid known problems with the current one and to make
    the computation more straightforward, which also happens to improve
    performance in multiple benchmarks a bit (Rafael Wysocki).

    - Improve two comments in the intel_pstate driver (Rafael Wysocki).

    - Fix the desired performance computation in the CPPC cpufreq driver
    (Hoan Tran).

    - Fix the devfreq core to avoid printing misleading error messages in
    some cases (Tobias Jakobi).

    - Fix the error code path in devfreq_add_device() to use proper
    locking around list modifications (Axel Lin).

    - Fix a build failure and remove a couple of redundant updates of

  • Resulting in a complete removal of a function basically implementing the
    inverse of vfs_readlink().

    As a bonus, now the proper security hook is also called.

  • This helper is for filesystems that want to read the symlink and are better
    off with the get_link() interface (returning a char *) rather than the
    readlink() interface (copy into a userspace buffer).

    Also call the LSM hook for readlink (not get_link) since this is for
    symlink reading not following.

  • All filesystems that are backers for overlayfs would also use
    generic_readlink(). Move this logic to the overlay itself, which is a nice
    cleanup.

  • Pull nfsd updates from Bruce Fields:
    "Some RDMA work and some good bugfixes, and two new features that could
    benefit from user testing:

    - Anna Schumacker contributed a simple NFSv4.2 COPY implementation.
    COPY is already supported on the client side, so a call to
    copy_file_range() on a recent client should now result in a
    server-side copy that doesn't require all the data to make a round
    trip to the client and back.

    - Jeff Layton implemented callbacks to notify clients when contended
    locks become available, which should reduce latency on workloads
    with contended locks"
