With a quick skim the code change looks good but I remember from
Matthew's talk that there was this issue that ExitBootServices() would
cause a yet another event?
I guess you could manually synthetize that event by reading the PCR
values right after ExitBootServices()?
Anyway, great work, thanks for making this effort.
