Uhm, no they're not.. both affect placement of a woken task but they're
complementary. WAKE_AFFINE is a check to see if it makes sense to run
the woken task on the same cpu as the wakee, BALANCE_WAKE does a full
load-balance pass, in case its combined with WAKE_AFFINE it does so in
case that test is negative.
