    Pull powerpc updates from Michael Ellerman:
     "Notable changes:
    
       - Removal of the NPU DMA code, used by the out-of-tree Nvidia driver,
         as well as some other functions only used by drivers that haven't
         (yet?) made it upstream.
    
       - A fix for a bug in our handling of hardware watchpoints (eg. perf
         record -e mem: ...) which could lead to register corruption and
         kernel crashes.
    
       - Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for
         vmalloc when using the Radix MMU.
    
       - A large but incremental rewrite of our exception handling code to
         use gas macros rather than multiple levels of nested CPP macros.
    
      And the usual small fixes, cleanups and improvements.
