What is "OpenCapp"? Is is different from OpenCAPI?

Is "store unit" not the same as "LSU" ? Use "LSU" uniformly if appropriate:

Need to reword this, I think. I propose "Average cycles per instruction
when the NTC instruction is a STCX instruction waiting for resolution
from the nest", which follows the form used by HWSYNC_COMPLETION_STALL_CPI,
below.
