** Description changed:

- Please enable CONFIG_SCOM_DEBUGFS for ppc64el kernels, this creates some
- new files in debugfs that allow userspace (root only) to access the
- P7/P8 chip internal XSCOM bus, which is needed for  various
- debug/diag/mfg tools. There should be no runtime impact on performance
- or stability by just enabling that option.
