This is being added to an Arm-only section, without it having an Arm-only
name. Judging from the diffstat in the cover letter, there's hardly any
abstraction in common code, so likely adding an ARM_ prefix to the name
would be the way to go (for now, i.e. if doing proper abstraction is
specifically not a goal).
