I can rename to match the x86-64 name.

I will do that in my tree.

That is what this patch is building towards, but the boot option is
"free", so why not?  In the meantime, it helps non-paravirt kernels
booted in a VM.
Hmm, you meant they paniced before?  If they just fail a few tests
that is not particularly worrying (real hardware does that often too)
Yes, they sometimes fail to boot, and the failure message used to ask us to pester mingo.

I still think we should figure that out automatically. Letting
the Hypervisor pass magic boot options seems somehow unclean.

But i suppose it will only work for the paravirtualized case,
not for the case of kernel running "native" under a hypervisor
I suppose? Or does that one not panic?

That is the one that can panic, for now. Fixing the paravirtualized case is easy, but we can't assume paravirtualization just yet.
