The only functional change is in the last patch which uses the core irq_alloc_desc*() infrastructure to allocating irqs. I know I've left race conditions in the code; specifically the unlikely case of two threads trying to map the same interrupt at the same time. Both will see that it isn't allocated, and both will do the allocation (I think). I need to hack on it more, but I wanted to get your feedback. Ultimately I'm hoping to be rid of the irq_map table entirely. g. --- Grant Likely (4): powerpc: stop exporting irq_map powerpc: make irq_{alloc,free}_virt private and remove count argument powerpc: move irq_alloc_descs_at() call into irq_alloc_virt() powerpc: use irq_alloc_desc() to manage irq allocations arch/microblaze/kernel/setup.c | 2 arch/powerpc/include/asm/irq.h | 47 ------ arch/powerpc/kernel/irq.c | 162 +++++++++++----------- arch/powerpc/platforms/512x/mpc5121_ads_cpld.c | 4 - arch/powerpc/platforms/52xx/media5200.c | 4 - arch/powerpc/platforms/52xx/mpc52xx_pic.c | 79 ++--------- arch/powerpc/platforms/82xx/pq2ads-pci-pic.c | 4 - arch/powerpc/platforms/85xx/socrates_fpga_pic.c | 26 +--- arch/powerpc/platforms/86xx/gef_pic.c | 10 - arch/powerpc/platforms/8xx/m8xx_setup.c | 2 arch/powerpc/platforms/cell/axon_msi.c | 2 arch/powerpc/platforms/cell/spider-pic.c | 10 + arch/powerpc/platforms/embedded6xx/flipper-pic.c | 8 + arch/powerpc/platforms/embedded6xx/hlwd-pic.c | 8 + arch/powerpc/platforms/iseries/irq.c | 10 + arch/powerpc/platforms/powermac/pic.c | 12 +- arch/powerpc/platforms/pseries/ras.c | 4 - arch/powerpc/platforms/pseries/xics.c | 14 +- arch/powerpc/sysdev/cpm1.c | 8 + arch/powerpc/sysdev/cpm2_pic.c | 10 + arch/powerpc/sysdev/ipic.c | 16 +- arch/powerpc/sysdev/mpc8xx_pic.c | 10 + arch/powerpc/sysdev/mpc8xxx_gpio.c | 12 +- arch/powerpc/sysdev/mpic.c | 28 ++-- arch/powerpc/sysdev/mv64x60_pic.c | 14 +- arch/powerpc/sysdev/qe_lib/qe_ic.c | 6 - arch/powerpc/sysdev/uic.c | 12 +- arch/powerpc/sysdev/xilinx_intc.c | 8 + 28 files changed, 206 insertions(+), 326 deletions(-) -- Signature
