  SVN rev 209198 on 2010-06-15 09:19:33Z by kib
  
  Use critical sections instead of disabling local interrupts to ensure
  the consistency between PCPU fpcurthread and the state of the FPU.
  
  Explicitely assert that the calling conventions for fpudrop() are
  adhered too. In cpu_thread_exit(), add missed critical section entrance.
