__do_IRQ() is deprecated since a long time and there are plans to
remove
it for 2.6.30. 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.
