[PATCH] ipv6: reorder struct inet6_ifaddr to remove padding on 64 bit builds

[Richard Kennedy <richard@rsk.demon.co.uk>]

reorder struct inet6_ifaddr to remove padding on 64 bit builds
    
remove 8 bytes of padding so inet6_ifaddr becomes 192 bytes & fits into
a smaller slab.
    
Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk>
----
patch against v2.6.29-rc8

I've compiled & booted with this patch, modules ipv6 & ip6_tables load
successfully, but I've not run any other tests.

regards
Richard
