Ok, so if you put SNP host support into arch/x86/virt/svm/sev.c, that should work too and won't have any relation to CONFIG_HAS_CC_PLATFORM, right? The CC_PLATFORM thing is a way to check for confidential computing guest features by abstracting the capabilities so that you don't have to check *each* and *every* conf guest type in the conditionals and thus go nuts.
