Ah, I see. The MM folks are not known to be bash experts, which is why we limit
our bash scripts to a bare minimum (and focus on C tests).

We do have some rather simple bash tests that are mostly used to load special
test kernel modules, where the real test logic resides.

For smaller things, I wouldn't mind a bash script in tools/mm. But the parsing
of pageflags is a bit ... advanced :)

Note that we already have some kpageflags processing in tools/mm/page-types.c,
not sure whether some of that could just easily be reused.
