From e9edb232d3b0848457a83a5b697f55264542892f Mon Sep 17 00:00:00 2001 From: Gautham R Shenoy Date: Thu, 10 Dec 2009 01:19:37 +0000 Subject: powerpc/pseries: Don't panic when H_PROD fails during cpu-online. If an online-attempt on a CPU which has been offlined using H_CEDE with an appropriate cede latency hint fails, don't panic. Instead print the error message and let the __cpu_up() code notify the CPU Hotplug framework of the failure, which in turn can notify the other subsystem through CPU_UP_CANCELED.
