The MIPS platforms seem to fall into three classes: o Platforms setting CONFIG_GENERIC_HARDIRQS_NO__DO_IRQ to explicitly disable __do_IRQ(): capcella_defconfig, cobalt_defconfig, e55_defconfig, fulong_defconfig, ip27_defconfig, jazz_defconfig, jmr3927_defconfig, lasat_defconfig, mpc30x_defconfig, pnx8335-stb225_defconfig, pnx8550-jbs_defconfig, pnx8550-stb810_defconfig, rb532_defconfig, rbtx49xx_defconfig, tb0219_defconfig, tb0226_defconfig, tb0287_defconfig and workpad_defconfig. o Platforms that don't set CONFIG_GENERIC_HARDIRQS_NO__DO_IRQ but don't seem to use __do_IRQ(): bcm47xx_defconfig, cavium-octeon_defconfig, excite_defconfig, ip22_defconfig, ip28_defconfig, msp71xx_defconfig, wrppmc_defconfig, o Platforms that still seem to rely on __do_IRQ(): o All Sibyte platforms: bigsur_defconfig and sb1250-swarm_defconfig o All Alchemy platforms: db1000_defconfig, db1100_defconfig, db1200_defconfig, db1500_defconfig, db1550_defconfig, mtx1_defconfig, pb1100_defconfig, pb1500_defconfig and pb1550_defconfig o malta_defconfig. The platform code itself is ok but irq-gic.c, irq-msc01.c, irq-msc01.c and irq_cpu.c are still using set_irq_chip and need fixing. o And the rest: decstation_defconfig, emma2rh_defconfig, ip32_defconfig, yosemite_defconfig, mipssim_defconfig and rm200_defconfig. For now I've checked in the following patch into linux-queue. Ralf MIPS: Enable GENERIC_HARDIRQS_NO__DO_IRQ for all platforms __do_IRQ() is deprecated and will go away.
