Indeed. :(

So pretty much all what matches in MAINTAINERS entries where my name
happened to end up for some reasons. That would be a good start.

Might be a bit overbroad as it also includes x86/kvm, x86/xen, x86/pci
which I'm not that involved with, but to make it simple for you, I just
volunteered the relevant maintainers (CCed) to participate in that
experiment. :)
