The option is CONFIG_XEN_MCE_LOG.
The question here is whether do we want to still build the kernel ourself, as 3.19 from Fedora repo works pretty well. If we decide to drop our kernel, move this feature request to Fedora.

For my experience Kernel 3.19 from Fedora works a lot better, than Kernel 3.18 from Qubes OS. I would prefer to drop the Qubes OS 3.18 kernel.
Especially because the Fedora team has a lot more resources than the Qubes OS team.

Disable Xen MCE log device 
It fails during initialization (/dev/mcelog chrdev is already
registered), so not useful anyway.
