[Crash-utility] Problem with irq command on ARM core file

Hi Dave I tried the irq command on an ARM vmcore file with a fairly new kernel (3.4.0) and it did not work. crash> irq irq: cannot determine number of IRQs The problem is in arm.c if (symbol_exists("irq_desc")) ARRAY_LENGTH_INIT(machdep->nr_irqs, irq_desc, "irq_desc", NULL, 0); as the symbol irq_desc does not exist any longer. Looking at x86_64.c I changed this to if (symbol_exists("irq_desc")) ARRAY_LENGTH_INIT(machdep->nr_irqs, irq_desc, "irq_desc", NULL, 0); else if (kernel_symbol_exists("nr_irqs")) get_symbol_data("nr_irqs", sizeof(unsigned int), &machdep->nr_irqs); and then the command worked as it should again.
