I'm really wondering what would be the best way to make these stats
available to userspace.  As mentioned, putting them into sysfs would
violate the one value/one file rule.  The use of /proc is discouraged.
debugfs was mentioned, but I have never used it.  Noticed that debugfs
was enabled in the default config (at least for pseries).  Looks like
that would be the best alternative.  Agree?
