- Clear kobject in percpu device_mce before calling sysdev_register() with
Because mce_create_device() may fail and it leaves kobject filled with
junk. It will be the problem when mce_create_device() will be called
next time.
- Fix error handling in mce_create_device()
Error handling should not do sysdev_remove_file() with not yet added
attributes.
- Don't register hotcpu notifier when mce_create_device() returns error
- Do mce_create_device() in CPU_UP_PREPARE instead of CPU_ONLINE
