Subject: Re: [PATCH 03/19] arm: expose number of page table levels on Kconfig
 level

It'd be nice to see the cover for this series so that people know the
reason behind this change is.  Maybe it'd be a good idea to add a
pointer or some description below the "---" to such patches which
are otherwise totally meaningless to the people you add to the Cc
line?
