Linus Torvalds 5b0e2cb020 powerpc updates for 4.15 
Non-highlights:
 
  - 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.
 
 Highlights:
 
  - 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 Power9.
 
  - 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.
