[PATCH 1/3] mm: add include files so that function definitions have a prototype

["Adeodato Simó" <dato@net.com.org.es>]

Previously, rodata_test(), usercopy_warn(), and usercopy_abort() were
defined without a matching prototype. Detected by -Wmissing-prototypes
GCC flag.

Signed-off-by: Adeodato Simó <dato@net.com.org.es>

I started poking at this after kernel-janitors got the suggestion[1]
to look into the -Wmissing-prototypes warnings.

Thanks for considering!
