Hmm... does the first part with like locating particular CPU cores?
I'd start also the sentence with the action taken except assuring
why the undefined action is taken.
"Add the MSR values required by Secure Launch (SL) to locate particular
CPU cores during application processor (AP) startup, and restore the
MTRR state after a Intel TXT launch."
Along the lines would be more informative...
