Joerg Roedel 893a5ab6ee KVM: SVM: Make sure KERNEL_GS_BASE is valid when loading gs_index ... The gs_index loading code uses the swapgs instruction to switch to the user gs_base temporarily. This is unsave in an lightweight exit-path in KVM on AMD because the KERNEL_GS_BASE MSR is switches lazily. An NMI happening in the critical path of load_gs_index may use the wrong GS_BASE value then leading to unpredictable behavior, e.g. a triple-fault. This patch fixes the issue by making sure that load_gs_index is called only with a valid KERNEL_GS_BASE value loaded in KVM.
