On x86-64 and ia64 they have a large issue because the ia32
emulation layer has to handle the fact that "long long" types
do not require 8-byte alignment, whereas 64-bit natively
they do.
So all things going over netlink that use u64 or similar have
potential structure layout issues due to this difference.
