Subject: Re: [PATCH] powerpc/pseries: Enable PSTORE in pseries_defconfig

> Enable PSTORE in pseries_defconfig

Please add a "why" to your changelogs eg. "Now we have pstore support for
nvram on pseries, enable it in the default config"

"Why" you are changing something is more important than "what", since
you can always determine "what" is being changed, by looking at the diff.
The "why" will be long forgotten.

This should really be added in the right location on the config, not
just at the end.   ie.
