Hmm, looks like it.

I do remember the patch didn't apply to my tree, so I guess I accidentally
dropped a hunk when I was forcing it to apply.

I also should have looked closer, as the following aren't in the skiboot
version of opal-api.h. The skiboot and Linux versions of opal-api.h should be
in sync as much as possible.

Furthermore, I don't see the first two used at all, and the bottom three are
only used in one place in the driver. So I've just sucked the values into the
driver code and dropped the #defines. Patch coming shortly.

Also we're obviously not building this in any of our defconfigs. Can you please
send a patch to enable it for pseries_defconfig and ppc64_defconfig.

cheers
