Hi,

the attached patch fixes a bug in xfrm_send_policy_notify(). The space 
allocated in skb must include 'sizeof(struct xfrm_user_polexpire)', not 
'sizeof(struct xfrm_userpolicy_info)' which is shorter. On ia32 it 
worked, probably because of some space gained from aligning. 
Unfortunately on amd64 it didn't and finally led to BUG() & kernel hangup.

Please apply.

BTW The second patch attached does some obvious cleanup: replaces 
RTA_ALIGN(RTA_LENGTH(x)) with RTA_SPACE(x) and ditto for NLMSG_*() 
macros. Apply on top of the first one or drop it. It's up to you.
