From: Namhyung Kim <namhy...@kernel.org> By turning the addr_location->filtered member from a boolean to a u8 bitmap, reusing (and extending) the hist_filter enum for that.
This patch doesn't change the logic at all, as it keeps the meaning of al->filtered !0 to mean that the entry _was_ filtered, so no change in how this value is interpreted needs to be done at this point. This will be soon used in upcoming patches.
