Make lpfc legacy I/O port free
This is a patch written by Tomohiro Kusumi and submitted to
linux-scsi:
http://marc.info/?l=linux-scsi&m=118673720712152&w=2
The original patch comment:
This patch makes Emulex lpfc driver legacy I/O port free.
It has already been acked quite long time ago.
So I resubmit the patch.
http://lkml.org/lkml/2006/11/22/28
Current lpfc driver is already using pci_select_bars()
and pci_enable_device_bars() when the PCI bus has been reset.
So I think this patch should also be acked.

You didn't check the diffstat of this one:
lpfc_init.c | 11
lpfc_init.c.orig | 2475 ++++++++++++++++++++++++++++++++++++++++++++++++++++++-
2 files changed, 2481 insertions(+), 5 deletions(-)
I've manually removed all references to the lpfc_init.c.orig file that
popped into existence with this patch and was deleted with the
subsequent one.
