JFYI, when comparing v3.7-rc5 to v3.7-rc4[3], the summaries are:
  - build errors: +14/-4

14 regressions:
  + drivers/virt/fsl_hypervisor.c: error: 'MSR_GS' undeclared (first
use in this function):  => 799:93

These reports would be more useful if the actual .config were provided,
rather than just saying "powerpc randconfig".

This can be obtained from the kissb build system.
[1] http://kisskb.ellerman.id.au/kisskb/head/5614/ (all 117 configs)

I doubt this particular one is a regression; it looks like the dependencies

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

have always been too weak (patch sent) and you're just comparing different
randomly-generated configs.

Thanks for your patch!

powerpc-randconfig

  + error: relocation truncated to fit: R_PPC64_REL24 against symbol
`._mcount' defined in .text section in arch/powerpc/kernel/entry_64.o:
(.text+0x1ff9eb8) => (.text+0x1ffa274), (.text+0x1ff7840)

powerpc-allyesconfig

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

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.
