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

[Russell King - ARM Linux]

It'd be nice to see the cover for this series so that people know the

pointer or some description below the "---" to such patches which
are otherwise totally meaningless to the people you add to the Cc
line?
