Agreed. Let kernel and firmware figure it out when to apply quirk and
user space should not worry about firmware version.

I liked the other approach better where user space just needs to know
if 1:1 mapping are in effect or not and take decision based on that.

So once SGI firmware gets fixed for 1:1 mapping, and kernel knows it,
then user space will not have to be changed at all.
