From 991de2e59090e55c65a7f59a049142e3c480f7bd Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Wed, 10 Jun 2015 16:54:59 +0800 Subject: PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq() To support IOAPIC hotplug, we need to allocate PCI IRQ resources on demand and free them when not used anymore. Implement pcibios_alloc_irq() and pcibios_free_irq() to dynamically allocate and free PCI IRQs. Remove mp_should_keep_irq(), which is no longer used.
