    SubjectTypo transferred from Intel manual
    The arch/x86/lib/x86-opcode-map.txt file contains the line

    af: SCAS/W/D/Q rAX,Xv


    This is what the Intel manuals show, but it's not correct. The 'X' stands for

    Memory addressed by the DS:rSI register pair (for example, MOVS, CMPS,
    OUTS, or LODS).


    On the other hand 'Y' means (also see the ae byte entry for SCASB):

    Memory addressed by the ES:rDI register pair (for example, MOVS, CMPS,
    INS, STOS, or SCAS).


    Hence the following patch should be applied:
