#     powerpc/xmon: Fix disassembly since printf changes
#     
#     The recent change to add printf annotations to xmon inadvertently made
#     the disassembly output ugly, eg:
#     
#       c00000002001e058  7ee00026      mfcr    r23
#       c00000002001e05c  fffffffffae101a0      std     r23,416(r1)
#       c00000002001e060  fffffffff8230000      std     r1,0(r3)
#     
#     The problem being that negative 32-bit values are being displayed in
#     full 64-bits.
#     
#     The printf conversion was actually correct, we are passing unsigned
#     long so it should use "lx". But powerpc instructions are only 4 bytes
#     and the code only reads 4 bytes, so inst should really just be
#     unsigned int, and that also fixes the printing to look the way we
#     want:
#     
#       c00000002001e058  7ee00026      mfcr    r23
#       c00000002001e05c  fae101a0      std     r23,416(r1)
#       c00000002001e060  f8230000      std     r1,0(r3)
#
