[PATCH v2] PCI/DPC: Fix shared interrupt handling

2017-12-14 Thread Alex Williamson
DPC supports shared interrupts, but it plays very loosely with testing whether the interrupt is generated by DPC before generating spurious log messages, such as: dpc :10:01.2:pcie010: DPC containment event, status:0x1f00 source:0x Testing the status register for zero or -1 is not suffic
