    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 ..."
