    Subject[PATCH 11/25] KVM: x86 emulator: fix jmp r/m64 instruction
    Date
    From: Avi Kivity <avi@qumranet.com>

    jmp r/m64 doesn't require the rex.w prefix to indicate the operand size
    is 64 bits. Set the Stack attribute (even though it doesn't involve the
    stack, really) to indicate this.
