These headers are not necessary because those definitions in them
are action specific and are not shared for others. Just move them
into the C files.

I find this change very dubious.

grep told me it isn't:

$ git grep 'include.*tc_act/'
net/sched/act_csum.c:#include <linux/tc_act/tc_csum.h>
net/sched/act_gact.c:#include <linux/tc_act/tc_gact.h>
net/sched/act_ipt.c:#include <linux/tc_act/tc_ipt.h>
net/sched/act_mirred.c:#include <linux/tc_act/tc_mirred.h>
net/sched/act_nat.c:#include <linux/tc_act/tc_nat.h>
net/sched/act_pedit.c:#include <linux/tc_act/tc_pedit.h>
net/sched/act_simple.c:#include <linux/tc_act/tc_defact.h>
net/sched/act_skbedit.c:#include <linux/tc_act/tc_skbedit.h>

(those are uapi headers, which I don't touch.)

Like Eric, I think this is a dubious change.

There is nothing wrong with using these headers to define the
core data structures used by each of these actions modules.

I'm not applying this, sorry.

Nothing is wrong here, just that it is not necessary.

act_police defines similar stuffs in its C file, not a header.
I don't see any reason why others can't.
