Work around Erratum 721 for AMD Family 10h and 12h processors.
"Under a highly specific and detailed set of internal timing conditions,
the processor may incorrectly update the stack pointer after a long series
of push and/or near-call instructions, or a long series of pop and/or
near-return instructions. The processor must be in 64-bit mode for this
erratum to occur."
