Hi, just to get it right - As i thought the FPU emulator is not really optional - It is even required for fpu-enabled devices which means we should clean the code in that way that if the user decides to compile in the fpu emulator into the kernel we do an autodetection upfront and change some of the entry/exit/lazy_fpu stuff. If the user decides not to compile in the FPU Emulator he is on his own and we ignore the whole FPU stuff and simply send SIGILL/SIGFPE to the processes causing all fpu binarys to fail on non-fpu enabled kernels.
