From: Babu Moger
Subject: [PATCH v3 2/7] target/i386: Add RAS feature bits on EPYC CPU models
Date: Thu, 24 Oct 2024 17:18:20 -0500

Add the support for following RAS features bits on AMD guests.

SUCCOR: Software uncorrectable error containment and recovery capability.
        The processor supports software containment of uncorrectable errors
        through context synchronizing data poisoning and deferred error
        interrupts.

McaOverflowRecov: MCA overflow recovery support.
