So this patch seems to be causing issues for the nommu build:
https://lore.kernel.org/oe-kbuild-all/202212062250.tR0otHcz-lkp@intel.com/

I had a bit of a poke at trying to see if there were some headers we
could pull in before actually checking the .config only to see:
# CONFIG_MMU is not set

Do we have to wrap the whole thing in a `#ifdef CONFIG_MMU` to fix
compilation here?

Thanks,
Conor.
