Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream-sev' into staging
* Migrate MSR_SMI_COUNT (Liran)
* Update kernel headers (Gerd, myself)
* SEV support (Brijesh)
I have not tested non-x86 compilation, but I reordered the SEV patches
so that all non-x86-specific changes go first to catch any possible
issues (which weren't there anyway :)).
