Unusual page allocation failure (network softirq related)

[David <david@xxxxxxxxxxxxxxx>]

Hi

Just for information, my home server produced the following allocation
failure this morning. First time I've seen it on this box. All seems
fine though, so no symptoms.

config & dmesg attached.

Cheers
David
