Cherry-pick 'fix build with Linux 3.2.0 headers' also to branch nm-1-0

[Petr Vorel <petr vorel gmail com>]

Hi there,

could you please cherry-pick commit 22b99e3b 'fix build with Linux 3.2.0 headers' also to
branch nm-1-0? It'd be nice to have it in 1.0.4 (not sure if it 1.0.4 is going to be made
from master or from nm-1-0).

Thanks a lot.

Kind regards,
Petr
