x86_emulate(): forgot to generate_exception_if() for 0xff?
...rch/x86/x86_emulate.c: x86_emulate():
1716 case 0xfe: /* Grp4 */
1717 generate_exception_if((m odrm_reg & 7) >= 2, EXC_UD);
1718 case 0xff: /* Grp5 */
1719 switch ( modrm_reg & 7 )
1720 {
1721 case 0: /* inc */
1722 emulate_1op("inc", dst, _regs.eflags);
1723 break;
1724 case 1: /* dec */
1725 emulate_1op("dec", dst, _regs.eflags);
1726 break;
Here we only check 0xfe for "reg >= 2"? I think we should also check
0xff -- we should swap...

float_trigo) sometime fail. (775)
