5f090dcb4d net: Remove unnecessary inclusions of asm/semaphore.h
None of these files use any of the functionality promised by
asm/semaphore.h.  It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

3c051235a7 [IPV6]: Fix dangling references on error in fib6_add().
Fixes bugzilla #8895

If a super-tree leaf has 'rt' assigned to it and we
get an error from fib6_add_rt2node(), we'll leave
a reference to 'rt' in pn->leaf and then do an
unconditional dst_free().

We should prune such references.

Based upon a report by Vincent Perrier.

e56d8b8a2e [INET]: Drop the inet_inherit_port() call.
As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.

Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
 `- tcp_v4_syn_recv_sock
     `- __inet_inherit_port
and the similar for DCCP are valid, but assumes BHs to be disabled.

554eb27782 [IP6TUNNEL]: Allow to create IP6 tunnels in net namespaces.
And no need in some IPPROTO_XXX enabling, since ipv6 code
doesn't have any filtering.

So, just set proper net and mark device with NETNS_LOCAL.

2f7f54b725 [IP6TUNNEL]: Use proper net instead of init_net stubs.
All the ip_route_output_key(), dev_get_by_...() and ipv6_chk_addr()
calls are now stubbed with init_net.

Fortunately, all the places already have where to get the proper
net from.

Can we please add a comment about why we do not need one?

d63a650736 [NETFILTER]: Add partial checksum validation helper
Move the UDP-Lite conntrack checksum validation to a generic helper
similar to nf_checksum() and make it fall back to nf_checksum()
in case the full packet is to be checksummed and hardware checksums
are available. This is to be used by DCCP conntrack, which also
needs to verify partial checksums.
