Wouldn't sysctl be /proc/sys/something again.

I did look under /sys but couldn't come up with a location to create 
this new file.

Although creating new files under /proc is frowned upon, the subset of 
files in the directory
seemed similar in functionality and connected to the new file I was 
creating and hence this new file in
/proc/ppc64/rtas.

linux:/proc/ppc64/rtas # ls -x
.         ..          clock    error_log  frequency  poweron  poweron_auto
progress  rmo_buffer  sensors  volume

I don't mind creating a /sys entry if anyone has a good suggestion.
