Subject: netfilter: xtables: combine struct xt_match_param and xt_target_param

It is possible to combine them, as extensions are evaluated serially,
and so, the callers end up a little smaller.

From 62fc8051083a334578c3f4b3488808f210b4565f Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Tue, 7 Jul 2009 20:42:08 +0200
Subject: netfilter: xtables: deconstify struct xt_action_param for matches

In future, layer-3 matches will be an xt module of their own, and
need to set the fragoff and thoff fields. Adding more pointers would
needlessy increase memory requirements (esp. so for 64-bit, where
pointers are wider).

From b4ba26119b06052888696491f614201817491a0d Mon Sep 17 00:00:00 2001

Subject: netfilter: xtables: change hotdrop pointer to direct modification

Since xt_action_param is writable, let's use it. The pointer to
'bool hotdrop' always worried (8 bytes (64-bit) to write 1 byte!).
Surprisingly results in a reduction in size:

   text    data     bss filename
5457066  692730  357892 vmlinux.o-prev
5456554  692730  357892 vmlinux.o

From 4538506be386f9736b83bf9892f829adbbb70fea Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Sat, 4 Jul 2009 12:50:00 +0200
Subject: netfilter: xtables: combine built-in extension structs

Prepare the arrays for use with the multiregister function. The
future layer-3 xt matches can then be easily added to it without
needing more (un)register code.

Subject: netfilter: change NF_ASSERT to WARN_ON

Change netfilter asserts to standard WARN_ON. This has the
benefit of backtrace info and also causes netfilter errors
to show up on kerneloops.org.

From 736d58e3a2245ac2779fe0f278f8735bcf33ca8d Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Thu, 13 May 2010 15:16:27 +0200
Subject: netfilter: remove unnecessary returns from void function()s

This patch removes from net/ netfilter files
all the unnecessary return; statements that precede the
last closing brace of void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

Signed-off-by: Joe Perches <joe@perches.com>
[Patrick: changed to keep return statements in otherwise empty function bodies]
Signed-off-by: Patrick McHardy <kaber@trash.net>
