Prev: [PATCH 12/12] x86: remove arch_probe_nr_irqs
Next: [PATCH -mmotm 0/4] memcg: per cgroup dirty limit (v4)
From: Yinghai Lu on 4 Mar 2010 05:20 don't clear that in arch_early_irq_init probe_nr_irqs_gsi is always called when ioapic is selected in config. so even for mrst, print out from probe_nr_irqs_gsi is report correct nr_irqs_gsi -v2: remove io_apic_irqs assignement, setup_IO_APIC will do that.
