Modified Files:
        src/sys/arch/amd64/amd64: fpu.c

Log Message:
fix some problems with lazy fpu context handling:
-if a new process gets a CPU with an FPU state of another process, it
 needs to initialize it to a clean state
 (actually, put the "fninit" where it belongs logically)
-initialize mxcsr as well
minor cleanup/optimization
Signal delivery after unmasking some cause is still broken - it doesn't
care about xmm exceptions. For now, set at least si_code to something
positive so that it doesn't look like a user generated asynchonous signal.
