Merge branch 'nla_align-set-4' 



Nicolas Dichtel says:

====================
netlink: align attributes when needed (patchset #3)

This is the continuation (series #3) of the work done to align netlink
attributes when these attributes contain some 64-bit fields.

It's the last patchset from what I've seen.

The last user of nla_put_u64() is block/drbd. This module does not use
standard netlink API (see all the stuff in include/linux/genl_magic_struct.h
and include/linux/genl_magic_func.h). I didn't modify it because it's seems
hard to do it whithout testing and fully understanding the context (for
example, why include/linux/drbd_genl.h is not part of uapi?).
Any thoughts?
