I really don't think we should separate kpagecgroup from kpagecount and kpageflags, because they look very similar (each of them is read-only, contains an array of u64 values referenced by PFN). Scattering these files between different filesystems would look ugly IMO. However, kpageidle is somewhat different (it's read-write, contains a bitmap) so I think it's worth moving it to /sys/kernel/mm. We have to move the code from fs/proc to mm/something then to remove dependency from PROC_FS, which would be unnecessary. Let me give it a try.
