MCE: Move MCE work initialization to before enabling machine checks Move the initialization of the mce work variable to before machine checks are enabled in the CPU. Also add a memory barrier to make sure the compiler doesn't move this. This closes a (very unlikely and small) race window where a machine check could happen before the work variable was initialized.
