      block: blk-merge: fast-clone bio when splitting rw bios · 52cc6eea
      Ming Lei authored
      biovecs has become immutable since v3.13, so it isn't necessary
      to allocate biovecs for the new cloned bios, then we can save
      one extra biovecs allocation/copy, and the allocation is often
      not fixed-length and a bit more expensive.
      
      For example, if the 'max_sectors_kb' of null blk's queue is set
      as 16(32 sectors) via sysfs just for making more splits, this patch
      can increase throught about ~70% in the sequential read test over
      null_blk(direct io, bs: 1M).

      This fixes a performance regression introduced by commit 54efd50b,
      and allows us to take full advantage of the fact that we have immutable
      bio_vecs. Hand applied, as it rejected violently with commit
      5014c311.

      null_blk: fix wrong capacity when bs is not 512 bytes · 5fdb7e1b
      Matias Bjørling authored
      set_capacity() sets device's capacity using 512 bytes sectors.
      null_blk calculates the number of sectors by size / bs, which
      set_capacity is called with. This led to null_blk exposing the
      wrong number of sectors when bs is not 512 bytes.

      block: fix bogus compiler warnings in blk-merge.c · 5014c311
      Jens Axboe authored
      The compiler can't figure out that bvprv is initialized whenever 'prev'
      is set to 1 as well. Use a pointer to bvprv instead, setting it to NULL
      initially, and get rid of the 'prev' tracking. This dumbs it down
      enough that gcc is happy.

      Pull core block updates from Jens Axboe:
       "This first core part of the block IO changes contains:
      
         - Cleanup of the bio IO error signaling from Christoph.  We used to
           rely on the uptodate bit and passing around of an error, now we
           store the error in the bio itself.
      
         - Improvement of the above from myself, by shrinking the bio size
           down again to fit in two cachelines on x86-64.
      
         - Revert of the max_hw_sectors cap removal from a revision again,
           from Jeff Moyer.  This caused performance regressions in various
           tests.  Reinstate the limit, bump it to a more reasonable size
           instead.
      
         - Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.
           Most devices have huge trim limits, which can cause nasty latencies
           when deleting files.  Enable the admin to configure the size down.
           We will look into having a more sane default instead of UINT_MAX
           sectors.
      
         - Improvement of the SGP gaps logic from Keith Busch.
      
         - Enable the block core to handle arbitrarily sized bios, which
           enables a nice simplification of bio_add_page() (which is an IO hot
           path).  From Kent.
      
         - Improvements to the partition io stats accounting, making it
           faster.  From Ming Lei.
      
         - Also from Ming Lei, a basic fixup for overflow of the sysfs pending
           file in blk-mq, as well as a fix for a blk-mq timeout race
           condition.
      
         - Ming Lin has been carrying Kents above mentioned patches forward
           for a while, and testing them.  Ming also did a few fixes around
           that.
      
         - Sasha Levin found and fixed a use-after-free problem introduced by
           the bio->bi_error changes from Christoph.

      Pull power management and ACPI updates from Rafael Wysocki:
       "From the number of commits perspective, the biggest items are ACPICA
        and cpufreq changes with the latter taking the lead (over 50 commits).
      
        On the cpufreq front, there are many cleanups and minor fixes in the
        core and governors, driver updates etc.  We also have a new cpufreq
        driver for Mediatek MT8173 chips.
      
        ACPICA mostly updates its debug infrastructure and adds a number of
        fixes and cleanups for a good measure.
      
        The Operating Performance Points (OPP) framework is updated with new
        DT bindings and support for them among other things.
      
        We have a few updates of the generic power domains framework and a
        reorganization of the ACPI device enumeration code and bus type
        operations.
      
        And a lot of fixes and cleanups all over.
      
        Included is one branch from the MFD tree as it contains some
        PM-related driver core and ACPI PM changes a few other commits are
        based on.
      
        Specifics:
      
         - ACPICA update to upstream revision 20150818 including method
           tracing extensions to allow more in-depth AML debugging in the
           kernel and a number of assorted fixes and cleanups (Bob Moore, Lv
           Zheng, Markus Elfring).
      
         - ACPI sysfs code updates and a documentation update related to AML
           method tracing (Lv Zheng).
      
         - ACPI EC driver fix related to serialized evaluations of _Qxx
           methods and ACPI tools updates allowing the EC userspace tool to be
           built from the kernel source (Lv Zheng).
      
         - ACPI processor driver updates preparing it for future introduction
           of CPPC support and ACPI PCC mailbox driver updates (Ashwin
           Chaugule).
      
         - ACPI interrupts enumeration fix for a regression related to the
           handling of IRQ attribute conflicts between MADT and the ACPI
           namespace (Jiang Liu).
      
         - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi
           Kasagar).
      
         - ACPI device registration code reorganization to separate the
           sysfs-related code and bus type operations from the rest (Rafael J

      Pull user namespace updates from Eric Biederman:
       "This finishes up the changes to ensure proc and sysfs do not start
        implementing executable files, as the there are application today that
        are only secure because such files do not exist.
      
        It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that
        did not show the proper source for files bind mounted from
        /proc/<pid>/ns/*.
      
        It also straightens out the handling of clone flags related to user
        namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER)
        when files such as /proc/<pid>/environ are read while <pid> is calling
        unshare.  This winds up fixing a minor bug in unshare flag handling
        that dates back to the first version of unshare in the kernel.
      
        Finally, this fixes a minor regression caused by the introduction of
        sysfs_create_mount_point, which broke someone's in house application,
        by restoring the size of /sys/fs/cgroup to 0 bytes.  Apparently that
        application uses the directory size to determine if a tmpfs is mounted
        on /sys/fs/cgroup.
      
        The bind mount escape fixes are present in Al Viros for-next branch.
        and I expect them to come from there.  The bind mount escape is the
        last of the user namespace related security bugs that I am aware of"

       "Ladies and gentlemen, we proudly announce to you the latest branch of
        ARM device tree contents for the mainline kernel.  Come and see, come
        and see!
      
        No less than twentythree thousand lines of additions! Just imagine the
        joy you will have of using your mainline kernel on newly supported
        hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
        UniPhier hardware!
      
        For those of you feeling less adventurous, added hardware support on
        platforms such as TI DM814x and Gumstix Overo platforms might be more
        of your liking.
      
        We've got something for everyone here!
      
        Ahem.  Cough.  So, anyway...
      
        This is the usual large batch of DT updates.  Lots and lots of smaller
        changes, some of the larger ones to point out are:
      
         - Rockchip veyron (Chromebook) support, as well as several other new boards
         - DRM support on Atmel AT91SAM9N12EK
         - USB additions on some Allwinner platforms
         - Mediatek MT6580 support
         - Freescale i.MX6UL support
         - cleanups for Renesas shmobile platforms
         - lots of added devices on LPC18xx
         - lots of added devices and boards on UniPhier

       "A large cleanup branch this release, with a healthy 10k negative line

        Most of this is removal of legacy (non-DT) support of shmobile

        the plat-samsung directory is cleaned out by moving most of the
        previously shared-location-but-not-actually-shared files from there to
        the appropriate mach directories instead.
