Hi Alex,
Today's linux-next merge of the vfio tree got a conflict in
drivers/pci/msi.c between commits a160fe94cb53 ("PCI/MSI: Remove unused
get_cached_msi_msg()") and 18ef822c59f6 ("PCI/MSI: Rename
__get_cached_msi_msg() to get_cached_msi_msg()") from the pci tree and
commit 3b307ffe3faa ("PCI: Export MSI message relevant functions") from
the vfio tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required). And then I added this merge fix patch (I should probably
also have added an include of linux/irq.h):

Someone needs to remember to send this fix to Linus when these 2 trees
are merged into his tree ...
