This is another prerequisite for enabling multiplatform support, and it is the part I am least certain about. I assume it will cause the extra boot message "Cannot allocate irq_descs @ IRQ%d, assuming pre-allocated" to be printed, but otherwise work ok. This definitely needs to be tested on real hardware to see if it works. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
