Please add Lothar's Reviewed-by for v7.  There's a number of minor
checkpatch.pl issues that checkpatch.pl can in turn fixup itself, please
correct them.

This needs a new Kconfig option and not to be enabled globally, only
when needed.

This wants <asm/spl.h> which is not globally available, so you need to
come up with something here.  At least making this Kconfig-enabled will
be a start and perhaps OK for now.

The last %d needs to be %zu since it's a size_t, for portability.

Thanks!
