Hi,
Booting kernel with both CONFIG_X86_MCE=y and CONFIG_XEN_MCE_LOG=y
results in "mce: Unable to init device /dev/mcelog (rc: -16)" error. I
think that's because both drivers tries to register that character
device (drivers/xen/mcelog.c: xen_late_init_mcelog;
arch/x86/kernel/cpu/mcheck/mce.c: mcheck_init_device). So obviously one
of them fails. CONFIG_XEN_MCE_LOG depends on CONFIG_X86_MCE...
How is that supposed to work?

Q: Why is top-posting such a bad thing?
