Subject: [PATCH 00/14] convert voyager over to the x86 quirks model

Given the lack of actual technical feedback, I went ahead and
implemented the additions to smp_ops and x86_quirks (and a dynamic mca
NMI hook) to allow voyager to be plumbed in.

There also needs to be changes in the boot setup to make voyager work
dynamically: It has to be detected first, so the a20 gate check is
only executed if a voyager is not found.

I also completed some of the subarchitecture eliminations, so all the
include file infrastructure should be gone.

The result is that I can boot both my PC SMP x86 boxes and voyager
with the same kernel.

This patch series applies on git head (obviously with
965c7ecaf2e2b083d711a01ab33735a4bdeee1a4 reverted)
