    Depends on how you count...
    If all .h files followed the rule - they should be selfcontained. In
    other words they should all include what they need this is correct.

    The correct figure is much less.
    I did a check with defconfig for i386.
    There are 7 .o files where config.h is not included - all are correct.
    lib/errno.c, arch/ia386/boot/bootsect.S + a few more.
    That was out of 983 .o files.

    There will be no slowdown introducing -iinclude (or -imacros) keeping
    these figures in mind.

    find -name '.*.o.cmd' | xargs grep __KERNEL__ to find number of .o files
    build.

    added grep -l 'include/linux/config.h' to find .o files build and where
    config-h was included. Then a simple diff..
