I did the following quick run with your patch and everything seems to be
working okay

64-bit build:
-------
1) Baremetal SME *enabled* - System boots fine
a) 32-bit guest launch : successful (KVM HV)
b) 64-bit guest launch : successful (KVM HV)
c) 64-bit SEV guest launch : successful (KVM HV)

2) Baremetal SME *disabled* - System boots fine
a) 32-bit guest launch : successful (KVM HV)
b) 64-bit guest launch : successful (KVM HV)
c) 64-bit SEV guest launch : successful (KVM HV)

32-bit build
----------
I am installing 32-bit distro to verify 32-bit baremetal boot and will
report my findings soon.
