arm-randconfig

While looking for more context, I noticed another regression that fell through
the cracks of my script:

    arch/arm/kernel/head.o: In function `stext':
    (.head.text+0x40): undefined reference to `CONFIG_PHYS_OFFSET'
    drivers/built-in.o: In function `v4l2_clk_set_rate':
    debugfs.c:(.text+0x11b9e0): undefined reference to `clk_round_rate'

  + error: misc.c: undefined reference to `ftrace_likely_update':  =>
.text+0x714), .text+0x94c), .text+0x3b8), .text+0xc10)

sh-randconfig

mips-allnoconfig
bigsur_defconfig
malta_defconfig
cavium_octeon_defconfig

Not really new, but it would be great if the MIPS people could get this
fixed for the final release.

Thanks!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
