When building a random powerpc kernel I hit this build error:

This patch simply add const to l_cpumask to fix this issue.

Thanks. I'm not sure why we haven't seen that.

Do you mind attaching your .config ?

Yes

Thanks.

So the key is:

CONFIG_PPC_POWERNV=3Dy

...

# CONFIG_NUMA is not set

Which none of our configs have.

I'll add a test build of that.

Thanks.

cheers
