Thomas Gleixner 3ed6cc9c2d x86/pci: Create PCI/MSI irqdomain after x86_init.pci.arch_init() 
commit 70245f86c109e0eafb92ea9653184c0e44b4b35c upstream.

Invoking x86_init.irqs.create_pci_msi_domain() before
x86_init.pci.arch_init() breaks XEN PV.

The XEN_PV specific pci.arch_init() function overrides the default
create_pci_msi_domain() which is obviously too late.

As a consequence the XEN PV PCI/MSI allocation goes through the native
path which runs out of vectors and causes malfunction.

Invoke it after x86_init.pci.arch_init().

Fixes: 6b15ffa07d ("x86/irq: Initialize PCI/MSI domain at PCI init time")
