Here are two patches that I just resurrected from an older branch
on my hard disk. They might come in handy when we finally switch
to an universal QEMU binary that contains both targets, the x86_64
and the i386 target at once. In this case we need the SMM code for
both, 32-bit and 64-bit mode in the binary, and select it during
runtime.

Thomas Huth (2):
  target/i386/tcg/sysemu: Move target specific SMM code to separate
    functions
  target/i386/tcg/sysemu: Allow 32-bit SMM code to be used in the 64-bit
    binary
