I know. That's why I'm asking.

Yap.

I don't think that's insurmountable.

The more important question is, can we do the same set of calls when
panic severity on all architectures which support APEI or should we have
arch-specific ghes_panic() callbacks or so.

As it is now, it would turn into a mess if we start with the ifdeffery
and the different requirements architectures might have...

Thx.
