linux-arch is obscure?? Where else do you send patches that affect
multiple architectures?

Already tried that. The only RAS tool that is currently in the kernel is
kexec/kdump and they insist on doing things their own way. That makes
it impossible to put a common RAS structure in place, because kexec
will not use it.
Sorry to keep beating on this drum, but kexec insist that their code
must have priority and that they do not trust the rest of the kernel.
Until that changes, there is no point is discussing how to make kexec
coexist with other RAS tools. If kexec change their mind then we can
look at using a common RAS interface, otherwise it is a waste of time
and I have better things to do with my life.
