mips/bigsur_defconfig
mips/malta_defconfig
mips/cavium_octeon_defconfig
mips/ip27_defconfig
and related warnings due to lack of -Werror on
ia64-defconfig
tilegx_defconfig
m32r/m32700ut.smp_defconfig
cpumask also gives fishy warnings:
lib/cpumask.c:167:25: warning: the address of 'cpu_all_bits' will
always evaluate as 'true' [-Waddress]
on sparc (e.g. sparc64/sparc64-allmodconfig) and powerpc (e.g.
powerpc/ppc64_defconfig), which seem to have been reported 6 months ago...
Can we throw some bitcoins at the cpumasks? ;-)

when I'm talking to journalists I just say "programmer" or something like that.
