From 1001b4d4a8ee6b2e7a6078a02ccdf68f91b192bd Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Thu, 30 May 2013 00:30:05 +0200 Subject: [PATCH] CPU: Fix sysfs cpu/online of offlined CPUs As reported by Dave Hansen, sysfs cpu/online shows 1 for offlined CPUs at boot. Fix this problem by initializing dev.offline with cpu_online() when registering a CPU.
