I'll be honest but, I don't think it's CTX_REG() that helps improve the
readability here.
The really odd part is that this sticks itself into a bare part of the
register state not surrounded by any LRI and after a BB_END. This
routine can only work for established contexts, it should not work for
execlists_init_reg_state.
Unless I am missing something change is completely mechanical, so any
question marks you have are already there, right? What do you suggest is
the action here?

Tvrtko
