    Pull powerpc updates from Michael Ellerman:
     "A bit of a small release, I suspect in part due to me travelling for
      KS. But my backlog of patches to review is smaller than usual, so I
      think in part folks just didn't send as much this cycle.
       - Five fixes for the >128T address space handling, both to fix bugs
         in our implementation and to bring the semantics exactly into line
         with x86.
       - Support for a new OPAL call on bare metal machines which gives us a
         true NMI (ie. is not masked by MSR[EE]=0) for debugging etc.
       - Support for Power9 DD2 in the CXL driver.
       - Improvements to machine check handling so that uncorrectable errors
         can be reported into the generic memory_failure() machinery.
       - Some fixes and improvements for VPHN, which is used under PowerVM
         to notify the Linux partition of topology changes.
       - Plumbing to enable TM (transactional memory) without suspend on
         some Power9 processors (PPC_FEATURE2_HTM_NO_SUSPEND).
       - Support for emulating vector loads form cache-inhibited memory, on
         some Power9 revisions.
       - Disable the fast-endian switch "syscall" by default (behind a
         CONFIG), we believe it has never had any users.
       - A major rework of the API drivers use when initiating and waiting
         for long running operations performed by OPAL firmware, and changes
         to the powernv_flash driver to use the new API.
       - Several fixes for the handling of FP/VMX/VSX while processes are
         using transactional memory.
       - Optimisations of TLB range flushes when using the radix MMU on
       - Improvements to the VAS facility used to access coprocessors on
         Power9, and related improvements to the way the NX crypto driver
         handles requests.
       - Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.
