Subject: Re: [tip:x86/urgent] x86/mce: Ensure offline CPUs don' t participate
 in rendezvous process

Hi,
	This patch requires all #MC exception errors set MCG_STATUS_RIPV = 1?
Because on offline CPUs, for #MC exception errors set MCG_STATUS_RIPV = 0
(like "Recoverable-not-continuable SRAR Type" Errors), this patch doesn't seem
to work. if this patch's "return; " in a wrong place?

Thanks
Tony W Wang-oc
