This Changelog is impenetrable. That is, I've no idea what you're
trying to say.

As to the patch, that makes hrtimer_reprogram exist unconditionally, but
the only callsite (so far) is condition on hrtimer_is_hres_active(),
which can only be true if HIGH_RES.

So what, except grow the image size, does this patch achieve?
