kib 120b1857f9 Clear the kernel grab of the FPU state on fork. The pcb_save pointer ... is already correctly reset to the FPU user save area, only PCB_KERNFPU flag might leak from old thread state into the new state. For creation of the user-mode thread, the change is nop since corresponding syscall code does not use FPU. On the other hand, creation of a kernel thread forks from a thread selected arbitrary from proc0, which might use FPU.
