Thanks. Khem's series failed since it doesn't cover 4.14, Bruce's
patchset helped a lot.

It looks like we have kernel failures with:

MACHINE="mpc8315e-rdb" DISTRO="poky-lsb" in linux-yocto 4.14
https://autobuilder.yocto.io/builders/nightly-ppc-lsb/builds/1051/steps/BuildImages_1/logs/stdio

MACHINE="mpc8315e-rdb" DISTRO="poky" in linux-yocto 4.15
https://autobuilder.yocto.io/builders/nightly-ppc/builds/1066/steps/BuildImages_1/logs/stdio

MACHINE="edgerouter" DISTRO="poky-lsb" in linux-yocto 4.14:
https://autobuilder.yocto.io/builders/nightly-mips-lsb/builds/1040/steps/BuildImages_1/logs/stdio

MACHINE="edgerouter" DISTRO="poky" in linux-yocto 4.15:
https://autobuilder.yocto.io/builders/nightly-mips/builds/1044/steps/BuildImages_1/logs/stdio

I realised the above may be due to missing BSP SRCREV updates (cc Kevin)?

With gcc 8, it seems we have a problem with meta-mingw:

The build isn't finished but I'm hoping these are the main remaining
issues.

Cheers,
