Thank you, this was actually really important remark and reminder.

OK so I think James' patch is stuck because of me, i.e.

https://lore.kernel.org/linux-integrity/20200911114820.GB6877@linux.intel.com/

I'm sorry about this. The final final conclusion is that the way it
exports PCRs is just fine.

Can you test this version?

I can then add reviewd-by and apply it and you don't have to do any sort
of stupid hacks.
