In the Linux kernel, the following vulnerability has been resolved: ARM:
footbridge: fix PCI interrupt mapping Since commit 30fdfb929e82 (“PCI: Add
a call to pci_assign_irq() in pci_device_probe()”), the PCI code will call
the IRQ mapping function whenever a PCI driver is probed. If these are
marked as __init, this causes an oops if a PCI driver is loaded or bound
after the kernel has initialised.
