Robin Murphy 235b2c776b PCI/MSI: Assume MSIs use real Requester ID, not an alias ... Currently, we handle all DMA aliases equally when calculating MSI requester IDs for the generic infrastructure. This turns out to be the wrong thing to do in the face of pure DMA quirks like those of Marvell SATA cards, where in the usual case the last thing seen in the alias walk is the DMA phantom function: we end up configuring the MSI doorbell to expect that alias, then find we have no interrupts since the MSI writes still come from the 'real' RID, thus get filtered out and ignored. Improve the alias walk to only account for the topological aliases that matter, based on the logic from the Intel IRQ remapping code.
