    That actually looks even more confusing. "read_always"? What the hell is

    Then make it what it is (with a long name...)

    if (jump_label_likely())

    if (jump_label_unlikely())

    That's probably the least confusing of the names. And for the cases we
    don't care:

    if (jump_label_branch())

    The above is the most descriptive and I would say the least confusing.
    Someone on IRC said that they wish it had jump_label in the name. As
    they see there's a "CONFIG_JUMP_LABEL" it tells us where those jump
    labels are used.

    Need to go and knock down the bike shed now.
