x86: Fix SCI on IOAPIC != 0
commit 18dce6ba5c8c6bd0f3ab4efa4cbdd698dab5c40a upstream.
Thomas Renninger <trenn@suse.de> reported on IBM x3330
booting a latest kernel on this machine results in:
PCI: PCI BIOS revision 2.10 entry at 0xfd61c, last bus=1
PCI: Using configuration type 1 for base access bio: create slab <bio-0> at 0
ACPI: SCI (IRQ30) allocation failed
ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control Interrupt handler (20090903/evevent-161)
ACPI: Unable to start the ACPI Interpreter
Later all kind of devices fail...
and bisect it down to this commit:
commit b9c61b70075c87a8612624736faf4a2de5b1ed30
x86/pci: update pirq_enable_irq() to setup io apic routing
it turns out we need to set irq routing for the sci on ioapic1 early.
-v2: make it work without sparseirq too.
-v3: fix checkpatch.pl warning, and cc to stable
