Hi Ben,
I'd like to ask about this patch ? Should I re-submit ?
Thanks,

This patch was simultaneously submitted to Red Hat for review. As a result of
that review, I'm withdrawing this patch and will submit a new version shortly.

patch touches mostly EEH and pseries code, but does require a couple of minor
additions to the overall PCI error recovery framework.

setting dev-error_state to pci_channel_io_normal.
The current implementation of EEH driver does not do so and requires the
following patch to correct this deficiency.
