Hello, Jeff.
This patch removes compiler warnings which are caused by using
ioports values (unsigned long) for the address argument of
read/write[bwl]() functions without casting.

NAK... These warnings exist as a reminder of the remaining
ioread/iowrite() work that must occur. Look at the 'iomap' and
'iomap-step1' branches of libata-dev.git for incomplete examples of this
work.
One must:
- create a data structure to store a bunch of I/O port values, as
returned by pci_iomap() and ioport_map()
- update legacy PCI IDE (aka looks like ISA IDE) code path to use
ioport_map() to obtain the I/O addresses we need
- update native mode PCI IDE (aka looks like PCI) code path to use
pci_iomap()
- update all the other drivers that use ioremap() to use pci_iomap()
- change struct ata_ioports, s/unsigned long/void __iomem */
- fix up the last few bits in each driver, such as
* eliminating the 'unsigned long base' variable in each
xxx_init_one() function
* changing the xxx_setup_port() function to indicate
void __iomem * rather than unsigned long
- one last check for any last s/long/void iomem */ changes to be made
- install Linus's "sparse" source checker
- run 'make C=1' in the kernel tree, and make sure libata and drivers
don't spew warnings
So... it's not as simple as just killing the warnings ;-)
