Subject: [PATCH v3 0/3] PCI/MSI: Cleanup init and improve 32-bit MSI checking

From: Bjorn Helgaas <bhelgaas@...gle.com>

MSI/MSI-X init was a little unconventional.  We had pci_msi_setup_pci_dev()
to disable MSI and MSI-X, in probe.c instead of msi.c so we could do it
even without CONFIG_PCI_MSI.  Move that to msi.c and fix the config issue
with an #ifdef.

Then add Vidya's patch on top.  Previous postings at

  PCI/MSI: Move MSI/MSI-X init to msi.c
  PCI/MSI: Move MSI/MSI-X flags updaters to msi.c

  PCI/MSI: Set device flag indicating only 32-bit MSI support
