9ccb363ec3 bochs style decode/execute of FPU instructions. 
With this coding style each instruction could be implemented separatelly even not together with current Bochs FPU emulator.
Step-by-step I am going to transfer all FPU instructions from current Bochs FPU emulator to new style and remove an old bugged emulator.
Anyway, now I could implement all currently missed FPU instructions without hacking wm-fpu-emu.

7f570b0150 Added PNI new streaming extensions instructions 
PNI could be enabled by setting BX_SUPPORT_PNI in config.h
After the feature will be fully validation I'll also add configure option.

The implemntation is ~complete. I've missed only three FPU new opcodes of FUSTTP instruction and MONITOR/WAIT instructions.

Enjoy ! ;)

6977467ed7 - fix flaw in IO bitmap permission handling (anonymous patch) 
From the author (see bug #663320) :
  In the code there is a check to verify that an IO bitmap
  is defined (io_base > BX_CPU_THIS_PTR
  tr.cache.u.tss386.limit_scaled) but there is no check if
  an accessed IO port's address actually falls within the
  defined limit of the TSS segment. So if I define an IO
  bitmap with 100 entries, port 101 may or may not be
  allowed depending on whatever bytes follow the TSS in
  memory
