Build error for undefined "node_reclaim_distance" has been reported on both
arch/sh/ and arch/powerpc64/.

Matt's patch here
https://lore.kernel.org/lkml/20191223164220.GA14394@xxxxxxxxxxxxxxxxxxx/

fixes the build error in both cases (both $ARCH-es), although it needs to be
resent as a patch instead of "can someone test this?".

Matt?
