[PATCH 27/49] arch/x86: replace bitmap_weight with bitmap_weight_{eq,gt,ge,lt,le} where appropriate

[Yury Norov]

__init_one_rdt_domain in rdtgroup.c code calls bitmap_weight() to compare
the weight of bitmap with a given number. We can do it more efficiently
with bitmap_weight_lt because conditional bitmap_weight() may stop
traversing the bitmap earlier, as soon as condition is (or can't be) met.
