memcg: clean up move charge
This patch cleans up move charge code by: - define functions to handle pte for each types, and make is_target_pte_for_mc() cleaner. - instead of checking the MOVE_CHARGE_TYPE_ANON bit, define a function that checks the bit. Signed-off-by:Daisuke Nishimura <nishimura@mxp.nes.nec.co.jp> Acked-by:
