[Upstream commit d65dfc81bb3894fdb68cbc74bbf5fb48d2354071]
The AMD severity grading function was introduced in kernel 4.1. The
current logic can possibly give MCE_AR_SEVERITY for uncorrectable
errors in kernel context. The system may then get stuck in a loop as
memory_failure

Do not add CC:stable when sending the patch with git send-email.

Our current AMD severity logic can possibly give MCE_AR_SEVERITY for
uncorrectable errors in kernel context. The current #MC handler only calls
memory_failure() on errors in user context, but older versions will call
memory_failure() unconditionally. In older versions, the sys
