Thomas Gleixner e982ad82bd genirq/msi: Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when no domain is present ... On architectures such as s390 that do not use irq domains for MSI, returning 0 as the maximum MSI index is a bit counter-productive, as it indicates that no MSI can be allocated. Bad idea. Instead, return the maximum we're willing to support in the MSI backing store (MSI_XA_DOMAIN_SIZE), and let the arch code do its usual thing. Thanks to Matthew Rosato for fixing the fix.
