Merge branch 'next' of git://git.monstr.eu/linux-2.6-microblaze
* 'next' of git://git.monstr.eu/linux-2.6-microblaze: microblaze: Update Microblaze defconfigs microblaze: Use klimit instead of _end for memory init microblaze: Enable ppoll syscall microblaze: Sane handling of missing timer/intc in device tree microblaze: use the generic ack_bad_irq implementation
