Implement a cheap way to count FPU interrupts for R2k/R3k DECstation systems. Do this manually in handcoded assembly, rather than calling `kstat_incr_irq_this_cpu' that would require setting up a stack frame and a lot of redirection. This is not going to be a problem because the FPU interrupt is local to the CPU and also there is one CPU only anyway. So at bootstrap determine the address of the correct location within `struct irq_desc', and then only refer to it directly in the interrupt handler. Signed-off-by: Maciej W.
