These reports would be more useful if the actual .config were provided, =20
rather than just saying "powerpc randconfig".
I doubt this particular one is a regression; it looks like the =20
dependencies have always been too weak (patch sent) and you're just =20
comparing different randomly-generated configs.

It's been over 3 years since powerpc-allyesconfig built (it's just too =20
big for the relocation model the kernel uses) -- how is this a =20
regression?

Hi Geert,
Thanks for these reports!

Yeah, as Scott said, these are not worth reporting. However, they are
being worked on in various ways, but will probably not be solved very
soon (it means we have to change how we link the kernel and that will
probably require some discussion).
I just keep the powerpc allyesconfig build there to catch other stuff
(like drivers that assume too much).

This can be obtained from the kissb build system.

Yeah, regressions in randconfigs can be misleading.
Still, they're build failures.

Thanks for your patch!

It's a regression because it didn't complain about ".mcount" in the
previous run.
But I'll start stripping them from the rc-incremental reports.
