SNP guest feature negotiation patch is part of tip now: https://lore.kernel.org/lkml/167414649850.4906.1693185384677559889.tip-bot2@tip-bot2/

MSR_AMD64_SNP_DEBUG_SWAP is already defined. As this requires guest side changes, please add MSR_AMD64_SNP_DEBUG_SWAP as part of SNP_FEATURES_PRESENT bit mask.

Regards
Nikunj
