From the peanut gallery, I'd just drop the "instruction(s)" qualifier, i.e.
- For TXT, APs are left halted using MONITOR/MWAIT.
Pedantically, it's the combination of MONTIOR+MWAIT that puts the CPU into a
sleep state, not the individual instructions.
And while I'm picking nits, the documentation is also a bit misleading as the CPU
isn't halted per se. I'd go with something like:
- For TXT, APs are left in an optimized (MONITOR/MWAIT) wait state.
