I just wanted to emphasize that it is not the schemata writing that needs to be protected, but instead the pseudo-locking code that runs after schemata programming that needs to run on a particular CPU.

Nah, that's not nitpicking - it is important that we sort out stuff fully before committing.
Now, I'm trying to understand what you're telling me and I believe you mean what update_domains() does, yes?
And I guess a more fitting subject in that case could be:
x86/intel_rdt: Ensure a CPU remains online for the region's pseudo-locking sequence
or so, and then the commit message explains in more detail what that title actually means. :)
Hmmm.
