Let users have a way to figure out if their distro set the kernel
timezone at all.

nf_conntrack_alloc cannot return NULL, so there is no need to check for
NULL before using the value.  I have also removed the initialization of ct
to NULL in nf_conntrack_alloc, since the value is never used, and since
perhaps it might lead one to think that return ct at the end might return
NULL.

The semantic patch that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@match exists@
expression x, E;
position p1,p2;
statement S1, S2;
@@

x@p1 = nf_conntrack_alloc(...)
... when != x = E
(
  if (x@p2 == NULL || ...) S1 else S2
|
  if (x@p2 == NULL && ...) S1 else S2
)

@other_match exists@
expression match.x, E1, E2;
position p1!=match.p1,match.p2;
@@

x@p1 = E1
... when != x = E2
x@p2

@ script:python depends on !other_match@
p1 << match.p1;
p2 << match.p2;

print "%s: call to nf_conntrack_alloc %s bad test %s" % (p1[0].file,p1[0].line,p2[0].line)

Commit 55b69e91 (netfilter: implement NFPROTO_UNSPEC as a wildcard
for extensions) broke revision probing for matches and targets that
are registered with NFPROTO_UNSPEC.

Fix by continuing the search on the NFPROTO_UNSPEC list if nothing
is found on the af-specific lists.

In future all cpumask ops will only be valid (in general) for bit
numbers < nr_cpu_ids.  So use that instead of NR_CPUS in iterators
and other comparisons.

This is always safe: no cpu number can be >= nr_cpu_ids, and
nr_cpu_ids is initialized to NR_CPUS at boot.

Fixed trivial IPv4/6 address printing conflicts in fs/cifs/connect.c due
to the conversion to %pI (in this networking merge) and the addition of
doing IPv6 addresses (from the earlier merge of CIFS).

The patch "don't call nf_log_packet in NFLOG module" make xt_NFLOG
dependant of nfnetlink_log. This patch forces the dependencies to fix
compilation in case only xt_NFLOG compilation was asked and modifies the
help message accordingly to the change.
