From 19ef9309273d26cb005cb23e6a370353dca91099 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 25 Jan 2008 21:08:34 +0100 Subject: printk: use ktime_get() printk timestamps: use ktime_get(). Some platforms have a functioning clocksource function only after they are done with early bootup, so delay this until out of SYSTEM_BOOTING state. it's also inherently safe now, as any bugs in this area will be caught by the printk recursion checks.
