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.
