You want me to pick this?

Dear Tony,


Thank you for your patch. It’d be great if you changed the commit 
message summary/title to be more specific. Currently, the short log, 
`git log --oneline`, is not very meaningful. Maybe:

tpm: Use new VFM macro INTEL_ATOM_AIRMONT

or

x86/cpu/vfm: Use macro INTEL_ATOM_AIRMONT in tpm


Kind regards,

Paul

This depends on patches 1,2,3 in this series. Boris may be applying those to TIP soon.

Are you Ok with this patch also going into the TIP tree to keep all the parts in sync?

Otherwise it can wait until this moves from TIP to Linus. I'm not in a great rush.

Paul,

With 74 patches in this series there was a lot of automation. I'll
see about updating "Subject:" lines to match subsystem conventions
before these are applied.

Apart from that, are you OK with the contents of this patch?

I don't mind Boris applying this. It is very unlikely to cause any
possible merge issues with other patches.

For the possible subject-line change: please *do not* remove my reviewed-by :-)
