src/sys/sys: workqueue.h
Log Message:
New workqueue flag WQ_FPU.
Arranges kthread_fpu_enter/exit around calls to the worker. Saves
cost over explicit calls to kthread_fpu_enter/exit in the worker by
only doing it once, since there's often a high cost to flushing the
icache and zeroing the fpu registers.
