+/* Dave Redman (djhr@tadpole.co.uk)
+ * changed these to function pointers.. it saves cycles and will allow
+ * the irq dependencies to be split into different files at a later date
+ * sun4c_irq.c, sun4m_irq.c etc so we could reduce the kernel size.
+ * Jakub Jelinek (jj@sunsite.mff.cuni.cz)
+ * Changed these to btfixup entities... It saves cycles :)
