Re: [BUG] powerpc does not save msi state [was Re: [PATCH 5/7] pci: Export the pci_restore_msi_state() function

That's a pity, but AFAIK it shouldn't be a problem because we don't
enable CONFIG_PM on those machines anyway. If we ever want to we'll need
to sort out with firmware how that will work WRT restoring MSI state.

I think the current generic code for pci_restore_msi_state() or whatever
it's called wilol directly call into write_msi_msg() etc... might be a
problem.
