Impact: find right nr_irqs_gsi on some systems. One test-system has gap between gsi's: [ 0.000000] ACPI: IOAPIC (id[0x04] address[0xfec00000] gsi_base[0]) [ 0.000000] IOAPIC[0]: apic_id 4, version 0, address 0xfec00000, GSI 0-23 [ 0.000000] ACPI: IOAPIC (id[0x05] address[0xfeafd000] gsi_base[48]) [ 0.000000] IOAPIC[1]: apic_id 5, version 0, address 0xfeafd000, GSI 48-54 [ 0.000000] ACPI: IOAPIC (id[0x06] address[0xfeafc000] gsi_base[56]) [ 0.000000] IOAPIC[2]: apic_id 6, version 0, address 0xfeafc000, GSI 56-62 ... [ 0.000000] nr_irqs_gsi: 38 So nr_irqs_gsi is not right. some irq for MSI will overwrite with io_apic. need to get that with acpi_probe_gsi when acpi io_apic is used Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
