    Pull second batch of powerpc updates from Michael Ellerman:
     "The highlight is the series that reworks the idle management on
      powernv, which allows us to use deeper idle states on those machines.
    
      There's the fix from Anton for the "BUG at kernel/smpboot.c:134!"
      problem.
    
      An i2c driver for powernv.  This is acked by Wolfram Sang, and he
      asked that we take it through the powerpc tree.
    
      A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of
      the audit maintainers.
    
      A patch from Ben to export the symbol map of our OPAL firmware as a
      sysfs file, so that tools can use it.
    
      Also some CXL fixes, a couple of powerpc perf fixes, a fix for
      smt-enabled, and the patch to add __force to get_user() so we can use
      bitwise types"
