From a80c49dbb6cd389fd5b0d79f850b56322475d00b Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 15 Nov 2010 21:11:12 +0100 Subject: [PATCH] serial8250: Mark console as CON_ANYTIME While trying to debug a cpu-hotplug issue I noticed printk() stopped working once the cpu got marked offline, since the 8250 serial console doesn't have any per-cpu resources the CON_ANYTIME bit is the safe and documented way to make it work again.
