Paolo Bonzini c8cc43c1ea selftests: KVM: avoid failures due to reserved HyperTransport region ... AMD proceessors define an address range that is reserved by HyperTransport and causes a failure if used for guest physical addresses. Avoid selftests failures by reserving those guest physical addresses; the rules are: - On parts with <40 bits, its fully hidden from software. - Before Fam17h, it was always 12G just below 1T, even if there was more RAM above this location. In this case we just not use any RAM above 1T. - On Fam17h and later, it is variable based on SME, and is either just below 2^48 (no encryption) or 2^43 (encryption).
