While fadump is a more reliable alternative to kdump dump capturing
method, it doesn't support passing additional parameters. Having
such support is desirable for two major reasons:

  1. It helps minimize the memory consumption of fadump dump capture
     kernel by disabling features that consume considerable amount of
     memory but have little significance for dump capture environment
     (eg. numa, cma, cgroup, etc.)
   2. It helps disable such features/components in dump capture kernel
      that are unstable and/or are being debugged.

Applied to powerpc/next.
