Guess it is known that this patch causes failures when building
"allmodconfig" on test systems such as 0day; it was reported by 0day
some two months ago. nevertheless, the patch found its way into mainline
without fix. Does anyone care, or should I simply disable "allmodconfig"
test builds for mips ?
