* Keep pointer to ->init_chipset method also in
struct ide_host and set it in ide_host_alloc_all().
* Add ide_pci_suspend() and ide_pci_resume() helpers
(default ->suspend and ->resume implementations).
* ->init_chipset can no longer be marked __devinit.
* Add proper PCI PM support to IDE PCI host drivers
(rz1000.c and tc86c001.c are skipped for now since
they need to be converted from using ->init_hwif
to use ->init_chipset instead).
v2:
* Cleanup CONFIG_PM #ifdef-s per akpm's suggestion.

Prefix messages from IDE PCI host drivers by driver name instead of marketed

basing on driver messages).
As a bonus this provides nice code savings for some drivers:

It turns out that const and __{dev}initdata cannot be mixed currently
and that generic IDE PCI host driver is also affected by the same issue:

This patch workarounds the problem in a bit hackish way but without
removing const from generic_chipsets[] (it adds const to __setup() so
__setup_str_ide_generic_all becomes const).
Now all __{dev}initdata data in generic IDE PCI host driver are read-only
so it builds again (driver's .init.data section gets marked as READONLY).

The change from __setup() to module_param_named() requires users to prefix
the option with "generic.".
This patch re-adds the __setup() additionally to the module_param_named().
Usually it would make sense getting rid of such an obsolete __setup() at
some time, but considering that drivers/ide/ is slowly approaching a RIP
status it's already implicitely scheduled for removal.
This patch fixes kernel Bugzilla #7353.

Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.
To fix this three things are needed.
#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports
The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.
The actual chip setup done by the quirk is the precise setup recommended
by the vendor.
(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

The ide-generic driver gives you DMA at bios tuned speed so can actually run a
lot of unsupported devices quite well. It has a pci table so that it doesn't
grab disks owned by other drivers but no way to override this. The patch adds
an option ide-generic-all which makes the driver grab everything going that is
IDE class.
The diff is messy because I put the special case as case 0 to make the if
conditional and long term maintenance easier.
This has been in Fedora for some time.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
