Hi all,

When I tried to review the code of ion, I find that there are many place
can be cleanup, so I post this patchset.

I mark it as v2, because I have post them in different patchset before[1][2]
[3][4]. And now, I combine them in one patchset to make it easy to review,
Meanwhile, I add some acks and rebase them to v4.15-rc1.

Thanks.
