Sounds to me like this fact should be a prominent part of the commit
message and these 1-4 patches should be carved out as a separate set
fixing that ACPI MADT thing and I should take them separately now...?

Also, does this need to go to stable although it is kinda big for
stable. If stable, do we need a smaller fix first which is backportable?

Thx.
