      Pull powerpc update from Benjamin Herrenschmidt:
       "The main highlights this time around are:
      
         - A pile of addition POWER8 bits and nits, such as updated
           performance counter support (Michael Ellerman), new branch history
           buffer support (Anshuman Khandual), base support for the new PCI
           host bridge when not using the hypervisor (Gavin Shan) and other
           random related bits and fixes from various contributors.
      
         - Some rework of our page table format by Aneesh Kumar which fixes a
           thing or two and paves the way for THP support.  THP itself will
           not make it this time around however.
      
         - More Freescale updates, including Altivec support on the new e6500
           cores, new PCI controller support, and a pile of new boards support
           and updates.
      
         - The usual batch of trivial cleanups & fixes"

        a patch in this branch to a early version of multiplatform conversion,
        but it ended up being reverted due to need of more bake time.  The

      Commit 32fcfd40 ("make vfree() safe to call from interrupt
      contexts") made it safe to do vfree directly from the RCU callback,
      which allows us to simplify ipc/util.c a lot by getting rid of the
      differences between vmalloc/kmalloc memory.

      net: Restore NETIF_F_* bit ordering. · 4ada8db3
      David Miller authored
      Commit 8ad227ff ("net: vlan: add 802.1ad support") added some new
      NETIF_F_* features bits, but it added them in the middle of existing
      values.
      
      Userland depends upon the flag bits via the per-netdevice 'flags' sysfs
      file.
      
      So restore the previous ordering by adding the new flags at the end.

      Michael Ellerman authored
      We are getting low on cpu feature bits. So rather than add a separate bit for
      every new Power8 feature, add a bit for arch 2.07 server catagory and use that
      instead.
      
      Hijack the value we had for BCTAR, but swap the value with CFAR so that all the
      ARCH defines are together.
      
      Note we don't touch CPU_FTR_TM, because it is conditionally enabled if
      the kernel is built with TM support.

      powerpc: Fix interrupt range check on debug exception · fc2a6cfe
      Bharat Bhushan authored
      We do not want to take single step and branch-taken debug exception
      in kernel exception code. But the address range check was not covering
      all kernel exception handlers address range.
      
      With this patch we defined the interrupt_end label which defines the
      end on kernel exception code. So now we check interrupt_base to
      interrupt_end range for not handling debug exception in kernel
      exception entry.
