[NETFILTER]: introduce and use aligned_u64 data type
As proposed by Andi Kleen, this is required esp. for x86_64 architecture, where 64bit code needs 8byte aligned 64bit data types, but 32bit userspace apps will only align to 4bytes. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
