[patch 2.6.16-mm2] Make fusion MPT driver legacy I/O port free

[Masao Fukuchi <fukuchi.masao@jp.fujitsu.com>]

Hi,

I made a patch for Fusion MPT driver to make PCI legacy I/O
port free.

The way to make PCI legacy I/O port free function is based on 
Kaneshige-san's patch which was uploaded several weeks ago and
is already merged into kernel 2.6.16-mm2.

Fusion MPT driver basically doesn't use PCI legacy I/O port.
But some PCI card/controller still use PCI legacy I/O port for
download boot operation.
So this driver needs to set I/O port at download boot operation.

I'm not a member of this mailing list, please cc to my e-mail 
address.

Thanks,
