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

From: Bjorn Helgaas <bhelgaas@google.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
