The kvm_get_linear_rip() handles x86/long mode cases well and has better readability, __kvm_set_rflags() also use the paired function kvm_is_linear_rip() to check the vcpu->arch.singlestep_rip set in kvm_arch_vcpu_ioctl_set_guest_debug(), so change the "CS.BASE + RIP" code in kvm_arch_vcpu_ioctl_set_guest_debug() and handle_exception_nmi() to this one.
