Working on my Arch Linux Server with an i5-6400

Tested rc2 against the Fedora build system (aarch64, ppc64le, s390x, x86_64), and boot tested x86_64. No regressions noted.

-rc2 looks grand on our RISC-V stuff..

Thanks,
Conor.

On ARCH_BRCMSTB using 32-bit and 64-bit kernels, build tested on BMIPS_GENERIC:
