6b5cde3629 cmd64x: set IDE_HFLAG_SERIALIZE explictly for CMD646
* Set IDE_HFLAG_SERIALIZE explictly for CMD646.

* Remove no longer needed ide_cmd646 chipset type (which has
  a nice side-effect of fixing handling of unexpected IRQs).

2a2ca6a961 ide: replace the global ide_lock spinlock by per-hwgroup spinlocks (v2)
Now that (almost) all host drivers have been fixed not to abuse ide_lock
and core code usage of ide_lock has been sanitized we may safely replace
ide_lock by per-hwgroup locks.

This patch is partially based on earlier patch from Ravikiran G Thirumalai.

While at it:
- don't use deprecated HWIF() and HWGROUP() macros
- update locking documentation in ide.h

v2:
Add missing spin_lock_init(&hwgroup->lock).  (Noticed by Elias Oltmanns)

0e63a588fc ide: fix IDE ACPI regression breaking suspend
Commit 4dde4492d8 ("ide: make drive->id
an union (take 2)") accidentally introduced an IDE ACPI regression which
at least on some machines confuses ACPI and breaks suspend. Fix it.

Fixes kernel.org bug :
http://bugzilla.kernel.org/show_bug.cgi?id=12279

[ Sorry about the bug (IDE ACPI is not used by default so it managed
  to slip in).  Still it is kind of surprising that the bug breaks
  suspend as it shouldn't impact anything except IDE ACPI (it seems
  that it uncovered either some ACPI/PM deficiency or a BIOS bug). ]

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  and ).

[ 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.
