    Pull powerpc updates from Michael Ellerman:
     "Highlights:
    
       - Infrastructure for secure boot on some bare metal Power9 machines.
         The firmware support is still in development, so the code here
         won't actually activate secure boot on any existing systems.
    
       - A change to xmon (our crash handler / pseudo-debugger) to restrict
         it to read-only mode when the kernel is lockdown'ed, otherwise it's
         trivial to drop into xmon and modify kernel data, such as the
         lockdown state.
    
       - Support for KASLR on 32-bit BookE machines (Freescale / NXP).
    
       - Fixes for our flush_icache_range() and __kernel_sync_dicache()
         (VDSO) to work with memory ranges >4GB.
    
       - Some reworks of the pseries CMM (Cooperative Memory Management)
         driver to make it behave more like other balloon drivers and enable
         some cleanups of generic mm code.
    
       - A series of fixes to our hardware breakpoint support to properly
         handle unaligned watchpoint addresses.
    
      Plus a bunch of other smaller improvements, fixes and cleanups.
