Did you really intend to write "SVM" rather than HVM? If yes, then to me 
"HVM guests on AMD" means the same as "SVM guests".
So I would suggest the following wording:

Support for VIRT_SSBD and MSR_SPEC_CTRL for HVM guests on AMD.

I would clarify that this is *only* creating the device-tree binding. 
IOW, there are no support for ACPI nor device-emulator (still in 
progress from Xen Project PoV).

I was under the impression that the code that was merged is enough to 
support the platform. Do you have any pointer where it says it is not 
sufficient?
