The long time delay has managed to muddle notes & recollection of prior discussions. This patch should have had a Signed-off-by: Matt Carlson <[EMAIL PROTECTED]> Signed-off-by: Michael Chan <[EMAIL PROTECTED]> on it; its the same patch that was submitted a long time ago. During the discussions of 21 Oct, it was proposed that there should be an arch hook for pci_restore_msi_state(), so that it would be treated at the same level as msi setup and teardown. I'd volunteered to write that patch. When I sat down to do it, however, I realized that I did not actually *need* it. And so I wondered: why am I writing un-needed, but theoretically proper, code? So I punted, and I didn't. Does that make sense? That's also why this patch is just a resubmission of the old patch.
