    KVM: PPC: Remove mmio_vsx_tx_sx_enabled in KVM MMIO emulation · 4eeb8556
    Simon Guo authored
    Originally PPC KVM MMIO emulation uses only 0~31#(5 bits) for VSR
    reg number, and use mmio_vsx_tx_sx_enabled field together for
    0~63# VSR regs.
    
    Currently PPC KVM MMIO emulation is reimplemented with analyse_instr()
    assistance.  analyse_instr() returns 0~63 for VSR register number, so
    it is not necessary to use additional mmio_vsx_tx_sx_enabled field
    any more.
    
    This patch extends related reg bits (expand io_gpr to u16 from u8
    and use 6 bits for VSR reg#), so that mmio_vsx_tx_sx_enabled can
    be removed.
