[PATCH 0/2] "nosnp" sev command line support

[Pavan Kumar Paluri]

Provide "nosnp" boot option via "sev=nosnp" kernel command line to
prevent SNP-capable host kernel from enabling SEV-SNP and initializing
RMP table.

On providing sev=nosnp via kernel command line:
cat /sys/module/kvm_amd/parameters/sev_snp should be "N".

This patchset is based on tip/master.

Any feedback is much appreciated.
