Konstantin Belousov 6cf9a08d2c Introduce the x86 kernel interfaces to allow kernel code to use ... FPU/SSE hardware. Caller should provide a save area that is chained into the stack of the areas; pcb save_area for usermode FPU state is on top. The pcb now contains a pointer to the current FPU saved area, used during FPUDNA handling and context switches. There is also a facility to allow the kernel thread to use pcb save_area. Change the dreaded warnings "npxdna in kernel mode!" into the panics when FPU usage is not registered.
