Nicolas Dichtel says:

====================
netlink: align attributes when needed (patchset #1)

This is the continuation of the work done to align netlink attributes
when these attributes contain some 64-bit fields.

David, if the third patch is too big (or maybe the series), I can split it.
Just tell me what you prefer.
====================
