[PATCH] x86/mce: show the status of cmci_disabled to user

[Xiaochun Lee]

From: Xiaochun Lee <lixc17@xxxxxxxxxx>

When enabled Firmware First mode in UEFI, we need to
set the cmci_disabled and ignore_ce in mca cfg
that users can check correct status from
"/sys/devices/system/machinecheck/machinecheckXXX/cmci_disabled"
