Merge tag 'zynq-cleanup-for-3.11' of git://git.xilinx.com/linux-xlnx into next/cleanup
From Michal Simek: arm: Xilinx Zynq cleanup patches for v3.11 This branch contains two fixes: - Fix zynq smp code - Do not specify init_irq ptr * tag 'zynq-cleanup-for-3.11' of git://git.xilinx.com/linux-xlnx: ARM: zynq: Not to rewrite jump code when starting address is 0x0 ARM: zynq: Remove init_irq declaration in machine description Signed-off-by: Arnd Bergmann <arnd@arndb.de>
