Add a function to allocate a range of interrupt vectors, which will
transparently use MSI-X and MSI if available or fallback to legacy
vectors. The interrupts are available in a core managed array in the
pci_dev structure, and can also be released using a similar function.
A new helper, __pci_enab

Add a helper to allocate a range of interrupt vectors, which will
transparently use MSI-X and MSI if available or fallback to legacy
vectors. The interrupts are available in a core managed array
in the pci_dev structure, and can also be released using a similar
helper.
