Re: [patch V2 19/46] x86/msi: Use generic MSI domain ops

From: Thomas Gleixner <redacted>

pci_msi_get_hwirq() and pci_msi_set_desc are not longer special. Enable the
generic MSI domain ops in the core and PCI MSI code unconditionally and get
rid of the x86 specific implementations in the X86 MSI code and in the
hyperv PCI driver.
