From 782274434d6f2e8aa8c573cb24fef94a164f2ce0 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 10 Jan 2019 22:57:35 +1100 Subject: powerpc: Stop using pr_cont() in __die() Using pr_cont() risks having our output interleaved with other output from other CPUs. Instead print everything in a single printk() call.
