Berrangé The 'qemu64' CPUID currently reports a family/model/stepping that approximately corresponds to an AMD K7 vintage architecture. The K7 series predates the introduction of 64-bit support by AMD in the K8 series. This has been reported to lead to LLVM complaints about generating 64-bit code for a 32-bit CPU target LLVM ERROR: 64-bit code requested on a subtarget that doesn't support it! It appears LLVM looks at the family/model/stepping, despite qemu64 reporting it is 64-bit capable. This patch changes 'qemu64' to report a CPUID with the family, model and stepping taken from a AMD Athlon(tm) 64 X2 Dual Core Processor 4000+ which is one of the first 64-bit AMD CPUs.
