      Pull block layer fixes from Jens Axboe:
       "Final small batch of fixes to be included before -rc1.  Some general
        cleanups in here as well, but some of the blk-mq fixes we need for the
        NVMe conversion and/or scsi-mq.  The pull request contains:
      
         - Support for not merging across a specified "chunk size", if set by
           the driver.  Some NVMe devices perform poorly for IO that crosses
           such a chunk, so we need to support it generically as part of
           request merging avoid having to do complicated split logic.  From
           me.
      
         - Bump max tag depth to 10Ki tags.  Some scsi devices have a huge
           shared tag space.  Before we failed with EINVAL if a too large tag
           depth was specified, now we truncate it and pass back the actual
           value.  From me.
      
         - Various blk-mq rq init fixes from me and others.
      
         - A fix for enter on a dying queue for blk-mq from Keith.  This is
           needed to prevent oopsing on hot device removal.
      
         - Fixup for blk-mq timer addition from Ming Lei.
      
         - Small round of performance fixes for mtip32xx from Sam Bradshaw.
      
         - Minor stack leak fix from Rickard Strandqvist.
      
         - Two __init annotations from Fabian Frederick"

      Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc · c5aec4c7
      Linus Torvalds authored
      Pull powerpc updates from Ben Herrenschmidt:
       "Here is the bulk of the powerpc changes for this merge window.  It got
        a bit delayed in part because I wasn't paying attention, and in part
        because I discovered I had a core PCI change without a PCI maintainer
        ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
        probably improve it later and I didn't want to rebase to add his ack.
      
        There is going to be a bit more next week, essentially fixes that I
        still want to sort through and test.
      
        The biggest item this time is the support to build the ppc64 LE kernel
        with our new v2 ABI.  We previously supported v2 userspace but the
        kernel itself was a tougher nut to crack.  This is now sorted mostly
        thanks to Anton and Rusty.
      
        We also have a fairly big series from Cedric that add support for
        64-bit LE zImage boot wrapper.  This was made harder by the fact that
        traditionally our zImage wrapper was always 32-bit, but our new LE
        toolchains don't really support 32-bit anymore (it's somewhat there
        but not really "supported") so we didn't want to rely on it.  This
        meant more churn that just endian fixes.
      
        This brings some more LE bits as well, such as the ability to run in
        LE mode without a hypervisor (ie. under OPAL firmware) by doing the
        right OPAL call to reinitialize the CPU to take HV interrupts in the
        right mode and the usual pile of endian fixes.
      
        There's another series from Gavin adding EEH improvements (one day we
        *will* have a release with less than 20 EEH patches, I promise!).
      
        Another highlight is the support for the "Split core" functionality on
        P8 by Michael.  This allows a P8 core to be split into "sub cores" of
        4 threads which allows the subcores to run different guests under KVM
        (the HW still doesn't support a partition per thread).
      
        And then the usual misc bits and fixes ..."
