Bartlomiej Zolnierkiewicz 6636487e8d amd74xx: workaround unreliable AltStatus register for nVidia controllers 
It seems that on some nVidia controllers using AltStatus register
can be unreliable so default to Status register if the PCI device
is in Compatibility Mode.  In order to achieve this:

* Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>.

* Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host
  driver for nVidia controllers in Compatibility Mode.

* Teach actual_try_to_identify() and drive_is_ready() about the new flag.

This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ
config option in 2.6.25 and using AltStatus register unconditionally when
available (kernel.org bugs #11659 and #10216).

[ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people
  and distributions use) it never worked correctly. ]

Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.
