//
// Abstract:
//
//    This module implements the routines to synchronize i/o on
//    the PowerPC.
//
//    This functionality will be provided by the use of intrinsics
//    in a future release of the compiler.  This module should be
//    deleted at that time.
//
//    I have tried to use the same names for these routines as we
//    expect the compiler intrinsic functions to be called.
