x86/ioapic: Split IOAPIC hot-removal into two steps The hot removal of IOAPIC is handling PCI and ACPI removal in one go. That only works when the PCI drivers released the interrupt resources, but breaks when a IOAPIC interrupt is still associated to a PCI device. The new pcibios_release_device() callback allows to solve that problem by splitting the removal into two steps: 1) PCI removal: Release all PCI resources including eventually not yet released IOAPIC interrupts via the new pcibios_release_device() callback. 2) ACPI removal: After release of all PCI resources the ACPI resources can be released without issue.
