  "message": "ARM: 6490/1: MM: bugfix: initialize spinlock for init_mm.context\n\ninit_mm used at kernel/sched.c:idle_task_exit() has spin_lock\n(init_mm.context.id_lock) that is not initialized when spin_lock/unlock\nis called at an ARM machine. Note that mm_struct.context.id_lock is\nusually initialized except for the instance of init_mm at\nlinux/arch/arm/mm/context.c\n\nNot initializing this spinlock incurs \"BUG: pinlock bad magic\"\nwarning when spinlock debug is enabled. We have observed such\ninstances when testing PM in S5PC210 machines.\n\nSigned-off-by: MyungJoo Ham \u003cmyungjoo.ham@samsung.com\u003e\nSigned-off-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n",
