Nadav Amit cfa0515dc4 KVM: x86: Fix far-jump to non-canonical check ... commit 7e46dddd6f upstream. Commit d1442d85cc ("KVM: x86: Handle errors when RIP is set during far jumps") introduced a bug that caused the fix to be incomplete. Due to incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may not trigger #GP. As we know, this imposes a security problem. In addition, the condition for two warnings was incorrect.
