Description:
		Read/write interface that reports the vector of SEV-SNP
		firmware vulnerability mitigations already verified by the
		firmware. Writing a vector value requests the firmware to
		VERIFY the corresponding mitigation bit(s).

		The list of supported mitigations and the meaning of each
		vector bit are both platform- and bug-specific and are
		published as part of the AMD Security Bulletin.
