    I think even the MTRR code (which is indeed one of the few x86
    places still not fully cleaned up) supports my arguments.

    Look at the averages:

    errors lines of code errors/KLOC
    arch/x86/kernel/cpu/mtrr/amd.c 2 120 16.6
    arch/x86/kernel/cpu/mtrr/centaur.c 8 225 35.5
    arch/x86/kernel/cpu/mtrr/cleanup.c 0 1102 0
    arch/x86/kernel/cpu/mtrr/cyrix.c 10 275 36.3
    arch/x86/kernel/cpu/mtrr/generic.c 16 730 21.9
    arch/x86/kernel/cpu/mtrr/if.c 11 428 25.7
    arch/x86/kernel/cpu/mtrr/main.c 50 751 66.5
    arch/x86/kernel/cpu/mtrr/state.c 0 83 0

    The arch/x86/kernel/cpu/mtrr/cleanup.c file is a new bit and
    relatively clean.
