[RFC 0/5] SEV Kernel Selftests

[Pratik R. Sampat]

This patchset introduces SEV-SNP test to the kernel selftest framework.
It also adds negative testing of SEV, ES and SNP VM types.

Patch 1 - Extend the sev smoke tests to use the SNP specific ioctl
calls and sets up memory to boot a SNP guest VM
Patch 2 - Cleanup patch that decouples the ioctl calls from the sev
selftest library with its test assert and status counterparts. No
functional change introduced
Patch 3 - Introduce ioctl test for SEV, ES
Patch 4 - Introduce positive and negative ioctl test for SEV-SNP
Patch 5 - Adds the X86_FEATURE_SEV_SNP vm type test for KVM_SEV_INIT2

Any feedback/review on the approach and design is highly appreciated!
