The series was split from my larger series sysctl-const series [0].
It only focusses on the proc_handlers but is an important step to be
able to move all static definitions of ctl_table into .rodata.

Split this per subsystem, please.

I've done a few painful API transitions before, and I don't think the
complexity of these changes needs a per-subsystem constification pass. I
think this series is the right approach, but that patch 11 will need
coordination with Linus. We regularly do system-wide prototype changes
like this right at the end of the merge window before -rc1 comes out.

That sounds good.

The requirements are pretty simple: it needs to be a obvious changes
(this certainly is) and as close to 100% mechanical as possible. I think
patch 11 easily qualifies. Linus should be able to run the same Coccinelle
script and get nearly the same results, etc. And all the other changes
need to have landed. This change also has no "silent failure" conditions:
anything mismatched will immediately stand out.

Unfortunately coccinelle alone is not sufficient, as some helpers with
different prototypes are called by handlers and themselves are calling
handler and therefore need to change in the same commit.
But if I add a diff for those on top of the coccinelle script to the
changelog it should be obvious.

So, have patches 1-10 go via their respective subsystems, and once all
of those are in Linus's tree, send patch 11 as a stand-alone PR.

Ack, I'll do that with the cover letter information requested by Joel.

(From patch 11, it looks like the seccomp read/write function changes
could be split out? I'll do that now...)

Thanks!

Thomas
