Both netconsole and netpoll keep a small preallocated pool of skbs

On the hot path they first attempt a normal GFP_ATOMIC allocation and only
fall back to the pool when that fails, keeping the pool as a last resort.
This is where the problem happens. If alloc_skb() fails, we now have
more than 100 message coming from the page=0 failure, which consumes the
scarce pool of skb, making the real issue disappear.

Here is the summary with links:

You are awesome, thank you!
