commit 8f0ea0fe3a036a47767f9c80e (snmp: reduce percpu needs by 50%)
reduced snmp array size to 1, so technically it doesn't have to be
an array any more. What's more, after the following commit:
commit 933393f58fef9963eac61db8093689544e29a600
Date: Thu Dec 22 11:58:51 2011 -0600
percpu: Remove irqsafe_cpu_xxx variants
We simply say that regular this_cpu use must be safe regardless of
preemption and interrupt state. That has no material change for x86
and s390 implementations of this_cpu operations. However, arches that
do not provide their own implementation for this_cpu operations will
now get code generated that disables interrupts instead of preemption.
probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after
almost 3 years, no one complains.
So, just convert the array to a single pointer and remove snmp_mib_init()
and snmp_mib_free() as well.

in6_dev_put() will be needed by vxlan module, so is
in6_dev_finish_destroy().

It is needed by vxlan module. Noticed by Mike.

In case IPv6 is compiled as a module, introduce a stub
for ipv6_sock_mc_join and ipv6_sock_mc_drop etc.. It will be used
by vxlan module. Suggested by Ben.
This is an ugly but easy solution for now.

commit f88c91ddba95 ("ipv6: statically link
register_inet6addr_notifier()" added following sparse warnings :
net/ipv6/addrconf_core.c:83:5: warning: symbol
'register_inet6addr_notifier' was not declared. Should it be static?
net/ipv6/addrconf_core.c:89:5: warning: symbol
'unregister_inet6addr_notifier' was not declared. Should it be static?
net/ipv6/addrconf_core.c:95:5: warning: symbol

Tomas reported the following build error:
net/built-in.o: In function `ieee80211_unregister_hw':
(.text+0x10f0e1): undefined reference to `unregister_inet6addr_notifier'
net/built-in.o: In function `ieee80211_register_hw':
(.text+0x10f610): undefined reference to `register_inet6addr_notifier'
make: *** [vmlinux] Error 1
when built IPv6 as a module.
So we have to statically link these symbols.

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

RFC 4291 section 2.4 states that all uncategorized addresses
should be considered as Global Unicast.
This will remove IPV6_ADDR_RESERVED completely
and return IPV6_ADDR_UNICAST in ipv6_addr_type() instead.

ipv6_addr_type() doesn't check for 'Unique Local IPv6 Unicast
Addresses' (RFC4193) and returns IPV6_ADDR_RESERVED for that range.
SCTP uses this function and will fail bind() and connect() calls that
use RFC4193 addresses, SCTP will also ignore inbound connections from
RFC4193 addresses if listening on IPV6_ADDR_ANY.
There may be other users of ipv6_addr_type() that could also have
problems.
