Most MSRs, plus the FPU, MMX, MXCSR, XMM and YMM registers should not be zeroed on INIT (Table 9-1 in the Intel SDM). Copy them out of CPUX86State and back in, instead of special casing env->pat. The relevant fields are already consecutive except PAT and SMBASE. However: - KVM and Hyper-V MSRs should be reset because they include memory locations written by the hypervisor. These MSRs are moved together at the end of the preserved area. - SVM state can be moved out of the way since it is written by VMRUN. Cc: Andreas Faerber <afaerber@suse.de> Reviewed-by: NMichael S.
