/* Dave Redman ([e-mail])
 * 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 ([e-mail])
 * Changed these to btfixup entities... It saves cycles :)
