      Pull virtio/vhost cross endian support from Michael Tsirkin:
       "I have just queued some more bugfix patches today but none fix
        regressions and none are related to these ones, so it looks like a
        good time for a merge for -rc1.
      
        The motivation for this is support for legacy BE guests on the new LE
        hosts.  There are two redeeming properties that made me merge this:
      
         - It's a trivial amount of code: since we wrap host/guest accesses
           anyway, almost all of it is well hidden from drivers.
      
         - Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY,
           and when it's clear, there's zero overhead (as some point it was
           tested by compiling with and without the patches, got the same
           stripped binary).
      
        Maybe we could create a Kconfig symbol to enforce the second point:
        prevent people from enabling it eg on x86.  I will look into this"

      drm/crtc: Fix edid length computation · e24ff467
      Shixin Zeng authored
      The length of each EDID block is EDID_LENGTH, and number of blocks is
      (1 + edid->extensions) - we need to multiply not add them.
      
      This causes wrong EDID to be passed on, and is a regression introduced
      by d2ed3436 (drm: Introduce helper for replacing blob properties)

      Linus Torvalds authored
      Pull user namespace updates from Eric Biederman:
       "Long ago and far away when user namespaces where young it was realized
        that allowing fresh mounts of proc and sysfs with only user namespace
        permissions could violate the basic rule that only root gets to decide
        if proc or sysfs should be mounted at all.
      
        Some hacks were put in place to reduce the worst of the damage could
        be done, and the common sense rule was adopted that fresh mounts of
        proc and sysfs should allow no more than bind mounts of proc and
        sysfs.  Unfortunately that rule has not been fully enforced.
      
        There are two kinds of gaps in that enforcement.  Only filesystems
        mounted on empty directories of proc and sysfs should be ignored but
        the test for empty directories was insufficient.  So in my tree
        directories on proc, sysctl and sysfs that will always be empty are
        created specially.  Every other technique is imperfect as an ordinary
        directory can have entries added even after a readdir returns and
        shows that the directory is empty.  Special creation of directories
        for mount points makes the code in the kernel a smidge clearer about
        it's purpose.  I asked container developers from the various container
        projects to help test this and no holes were found in the set of mount
        points on proc and sysfs that are created specially.
      
        This set of changes also starts enforcing the mount flags of fresh
        mounts of proc and sysfs are consistent with the existing mount of
        proc and sysfs.  I expected this to be the boring part of the work but
        unfortunately unprivileged userspace winds up mounting fresh copies of
        proc and sysfs with noexec and nosuid clear when root set those flags
        on the previous mount of proc and sysfs.  So for now only the atime,
        read-only and nodev attributes which userspace happens to keep
        consistent are enforced.  Dealing with the noexec and nosuid
        attributes remains for another time.
      
        This set of changes also addresses an issue with how open file
        descriptors from /proc/<pid>/ns/* are displayed.  Recently readlink of
        /proc/<pid>/fd has been triggering a WARN_ON that has not been
        meaningful since it was added (as all of the code in the kernel was
        converted) and is not now actively wrong.
      
        There is also a short list of issues that have not been fixed yet that
        I will mention briefly.
      
        It is possible to rename a directory from below to above a bind mount.
        At which point any directory pointers below the renamed directory can
        be walked up to the root directory of the filesystem.  With user
        namespaces enabled a bind mount of the bind mount can be created
        allowing the user to pick a directory whose children they can rename
        to outside of the bind mount.  This is challenging to fix and doubly
        so because all obvious solutions must touch code that is in the
        performance part of pathname resolution.
      
        As mentioned above there is also a question of how to ensure that
        developers by accident or with purpose do not introduce exectuable
        files on sysfs and proc and in doing so introduce security regressions
        in the current userspace that will not be immediately obvious and as
        such are likely to require breaking userspace in painful ways once
        they are recognized"

      arm64: Fix show_unhandled_signal_ratelimited usage · f871d268
      Suzuki K. Poulose authored
      Commit 86dca36e introduced ratelimited usage for
      'unhandled_signal' messages.
      The commit checks the ratelimit irrespective of whether
      the signal is handled or not, which is wrong and leads
      to false reports like the below in dmesg :
      
      __do_user_fault: 127 callbacks suppressed
      
      Do the ratelimit check only if the signal is unhandled.
      
      Fixes: 86dca36e ("arm64: use private ratelimit state along with show_unhandled_signals")

      ARM64 / SMP: Switch pr_err() to pr_debug() for disabled GICC entry · f9058929
      Hanjun Guo authored
      It is normal that firmware presents GICC entry or entries (processors)
      with disabled flag in ACPI MADT, taking a system of 16 cpus for example,
      ACPI firmware may present 8 ebabled first with another 8 cpus disabled
      in MADT, the disabled cpus can be hot-added later.
      
      Firmware may also present more cpus than the hardware actually has, but
      disabled the unused ones, and easily enable it when the hardware has such
      cpus to make the firmware code scalable.
      
      So that's not an error for disabled cpus in MADT, we can switch pr_err()
      to pr_debug() to make the boot a little quieter by default.
      
      Since hwid for disabled cpus often are invalid, and we check invalid hwid
      first in the code, for use case that hot add cpus later will be filtered
      out and will not be counted in possible cups, so move this check before
      the hwid one to prepare the code to count for disabeld cpus when cpu
      hot-plug is introduced.

      Pull ACPICA updates from Rafael Wysocki:
       "Additional ACPICA material for v4.2-rc1
      
        This will update the ACPICA code in the kernel to upstream revision
        20150619 (a bug-fix release mostly including stable-candidate fixes)
        and restore an earlier ACPICA commit that had to be reverted due to a
        regression introduced by it (the regression is addressed by
        blacklisting the only known system affected by it to date).
      
        The only new feature added by this update is the support for
        overriding objects in the ACPI namespace and a new ACPI table that can
        be used for that called the Override System Definition Table (OSDT).
        That should allow us to "patch" the ACPI namespace built from
        incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
        during system startup without the need to provide replacements for all
        of those tables in the future.
      
        Specifics:
      
         - Fix system resume problems related to 32-bit and 64-bit versions of
           the Firmware ACPI Control Structure (FACS) in the firmare (Lv

         - Restore the commit modifying _REV to always return "2" (as required
           by ACPI 6) and add a blacklisting mechanism for systems that may be
           affected by that change (Rafael J Wysocki)

      It's a bug in our Makefile rules, make it show what the changing
      certificate list was, and make it a warning so that people actually see
      it.

      ACPI / init: Make it possible to override _REV · 18d78b64
      Rafael J. Wysocki authored
      The platform firmware on some systems expects Linux to return "5" as
      the supported ACPI revision which makes it expose system configuration
      information in a special way.
      
      For example, based on what ACPI exports as the supported revision,
      Dell XPS 13 (2015) configures its audio device to either work in HDA
      mode or in I2S mode, where the former is supposed to be used on Linux
      until the latter is fully supported (in the kernel as well as in user
      space).
      
      Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later
      is supported by the OS, a subsequent change will make that happen, so
      make it possible to override that on systems where "5" is expected to
      be returned for Linux to work correctly one them (such as the Dell
      machine mentioned above).

      [IA64] Drop debug test/printk that some special pages are marked reserved · 43c518d1
      Tony Luck authored
      In commit 92923ca3 "mm: meminit: only set page reserved in the memblock region"
      we dropped setting the reserved bits for all pages. This results in some warnings
      on ia64:
      
      put_kernel_page: page at 0xe000000005588000 not in reserved memory
      put_kernel_page: page at 0xe000000005588000 not in reserved memory
      put_kernel_page: page at 0xe000000005580000 not in reserved memory
      put_kernel_page: page at 0xe000000005580000 not in reserved memory

      put_kernel_page: page at 0xe000000005580000 not in reserved memory
      
      the two different pages match up with two objects from the loaded kernel
      that get mapped by arch/ia64/mm/init.c:setup_gate()
      
      a000000101588000 D __start_gate_section
      a000000101580000 D empty_zero_page
      
      In a discussion with Mel Gorman:
        http://lkml.kernel.org/r/20150526102219.GB13750%40suse.de
      he suggested that while the preferred approach might be to
      set the reserved bit for these pages, it would also be OK
      to just drop the test:
         "as it's a debugging check that is ia-64 specific"
      
      After hunting around a bit and failin to find a good place to mark these
      pages as reserved - I decided to just delete the test.

        the patchset adds the ability to clone a fuse connection.  This means,

        device fd, the fuse daemon can have multiple distinct file descriptors

        currently the only constraint is that a request must be answered on
        the same fd as it was read from.
      
        This can be extended further to allow binding a device clone to a
        specific CPU or NUMA node.

        things that weren't easily categorized into any of the other previous
        series categories already requested for pull.
      
        That said, each fixup branch (including this one) is independent and
        there are no ordering constraints.  Only the final code relocation
        (which is NOT in this pull) requires that all my cleanup branches be
        merged first"

      Pull module_platform_driver replacement from Paul Gortmaker:
       "Replace module_platform_driver with builtin_platform driver in non
        modules.
      
        We see an increasing number of non-modular drivers using
        modular_driver() type register functions.  There are several downsides
        to letting this continue unchecked:
      
         - The code can appear modular to a reader of the code, and they won't
           know if the code really is modular without checking the Makefile
           and Kconfig to see if compilation is governed by a bool or
           tristate.
      
         - Coders of drivers may be tempted to code up an __exit function that
           is never used, just in order to satisfy the required three args of
           the modular registration function.
      
         - Non-modular code ends up including the <module.h> which increases
           CPP overhead that they don't need.
      
         - It hinders us from performing better separation of the module init
           code and the generic init code.
      
        So here we introduce similar macros for builtin drivers.  Then we
        convert builtin drivers (controlled by a bool Kconfig) by making the
        following type of mapping:
      
          module_platform_driver()       --->  builtin_platform_driver()
          module_platform_driver_probe() --->  builtin_platform_driver_probe().
      
        The set of drivers that are converted here are just the ones that
        showed up as relying on an implicit include of <module.h> during a
        pending header cleanup.  So we convert them here vs adding an include
        of <module.h> to non-modular code to avoid compile fails.  Additonal
        conversions can be done asynchronously at any time.
      
        Once again, an unused module_exit function that is removed here
        appears in the diffstat as an outlier wrt all the other changes"

      Pull module_init replacement part two from Paul Gortmaker:
       "Replace module_init with appropriate alternate initcall in non
        modules.
      
        This series converts non-modular code that is using the module_init()
        call to hook itself into the system to instead use one of our
        alternate priority initcalls.
      
        Unlike the previous series that used device_initcall and hence was a
        runtime no-op, these commits change to one of the alternate initcalls,
        because (a) we have them and (b) it seems like the right thing to do.
      
        For example, it would seem logical to use arch_initcall for arch
        specific setup code and fs_initcall for filesystem setup code.
      
        This does mean however, that changes in the init ordering will be
        taking place, and so there is a small risk that some kind of implicit
        init ordering issue may lie uncovered.  But I think it is still better
        to give these ones sensible priorities than to just assign them all to
        device_initcall in order to exactly preserve the old ordering.
      
        Thad said, we have already made similar changes in core kernel code in
        commit c96d6660 ("kernel: audit/fix non-modular users of
        module_init in core code") without any regressions reported, so this
        type of change isn't without precedent.  It has also got the same
        local testing and linux-next coverage as all the other pull requests
        that I'm sending for this merge window have got.
      
        Once again, there is an unused module_exit function removal that shows
        up as an outlier upon casual inspection of the diffstat"
