[tkreuzer] 35175: Implement FLOATOBJ api in assembly. ~~ On x86 (and only there) we must not use the FPU in kernel mode code, because the fpu state is not safed on normal context switches. That's why there's the FLOATOBJ api. It provides the needed fp emulation for win32k and drivers. I wrote it in asm to be fast. It's not yet plugged in.
