Guenter Roeck 4b08478422 Drop support for Renesas H8/300 (h8300) architecture
H8/300 has been dead for several years, and the kernel for it
has not compiled for ages. Drop support for it.

Thomas Gleixner 51f3f15945 h8300: Use generic irq Kconfig
Switch to the generic irq Kconfig. h8300 has all irq chips converted
to the new functions, so select the GENERIC_HARDIRQS_NO_DEPRECATED
switch as well. Fixup the resulting fallout in show_interrupts().

Thomas Gleixner f9f91ef5e3 h8300: Convert interrupt handling to flow handler
__do_IRQ is deprecated so h8300 needs to be converted to proper flow
handling. The irq chip is simple and does not required any
mask/ack/eoi functions, so we can use handle_simple_irq.

So could move kstat_irqs array to irq_desc struct.

(s390, m68k, sparc) are not touched yet, because they don't support genirq
