entry.S access percpu + global data defined in sun4m_irq.c - so move the types to irq.h. This makes sparse happy and allow us to utilize asm-offsets later. Also updated a few comments in the sun4m_irq.c file. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
