What happens if this patch is not applied.  This changelog does not
have enough information for me to judge the patch.  Unless I missed it
I do not see a patch 00/77 explaining the background of the change,
and a quick search did not turn up a discussion of why drivers now
need to call pci_msix_table_size() prior to pci_enable_msix.

Not sure why everybody needed to be cc'd on this one patch.  Please
put targeted cc's in the patches themselves.  If anything only patch
00/77 should go to the union of all addresses.
