Hi, all This patch is a small fix for avoiding gpf when writing non-zero value to MCA MCi_STATUS MSRs. According to spec, MCi_STATUS MSR could only be cleared to 0s. This error is found when doing cpu-offline cmci happens. For avoiding missing future cmci after changing cmci owner, we need to process pending cmci errors to clear MCi_STATUS MSRs. Since error count (38~52bit in MCi_STATUS) meet threasholds yet not cleared, this error might not be triggered for long. Thanks a lot!
