Make sure that a vmalloc(80000) will succeed, even if few pages need to
be swapped out.

Otherwise, some scripts using iptables will die while they where okay
before ?

I am not sure how GFP_NORETRY really works among different linux
kernels.

Maybe this flag has no effect for order-0 allocations anyway.
