This is a reworked version of the multivector MSI support for the designware
PCIe host controller driver.
v3 added patch 2 to share more code between the single and multivector MSI
code paths.
While not really related to this topic patches 4+5 fix the MSI message setup
to work on 64bit and 32bit PAE systems. I included them in this series as
they depend on patch 2.
v4 fixes the last patch to also set up the high part of the MSI target
address, when calling the common DW MSI init function.

Lucas
