Subject: [Patch] netpoll: allow spaces in its parameter

From: Amerigo Wang <[email-masked]>

It would be nice if we allow spaces in netconsole parameters,
otherwise we get weird results if there are spaces in it.

After this patch, we will allow things like:
 "netconsole= @192.168.0.1/eth0 , [email-masked]/".
