    I'm still a bit surprised, since in the rest of the kernel we are even
    going from -O2 to -Os for getting better performance.

    Robert said he wanted to post some numbers showing that -O3 is
    measurably better for you [1], but I haven't seen them.

    UTS_VERSION is already available and printed at the top of dmesg.
    I don't see the point in printing it a second time.
