This patchkit is amusing (or maybe sad) because it basically tries to reconstruct the original soft offline design using a user space daemon instead of doing policy badly in the kernel. You can still have it by enabling CONFIG_X86_MCELOG_LEGACY and use http://www.mcelog.org or an equivalent daemon of your chosing that listens to /dev/mcelog. -Andi
