Merge tag 'for-3.7' of git://openrisc.net/jonas/linux
Pull OpenRISC updates from Jonas Bonn: "Fixups for some corner cases, build issues, and some obvious bugs in IRQ handling. No major changes." * tag 'for-3.7' of git://openrisc.net/jonas/linux: openrisc: mask interrupts in irq_mask_ack function openrisc: fix typos in comments and warnings openrisc: PIC should act on domain-local irqs openrisc: Make cpu_relax() invoke barrier() audit: define AUDIT_ARCH_OPENRISC openrisc: delay: fix handling of counter overflow openrisc: delay: fix loops calculation for __const_udelay
