8911c9e334 [SCSI] aic79xx: fix MMIO for PPC 44x platforms
The driver stores the PCI resource address into 'u_long' variable before
calling ioremap_nocache() on it. This warrants kernel oops when the registers
are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space
mapped beyond 4 GB.

The arch/ppc/ kernel has a fixup in ioremap() that helps create an illusion
that the PCI memory resources are mapped below 4 GB, but arch/powerpc/ code
got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

3a2d5b7001 PM: Introduce PM_EVENT_HIBERNATE callback state
During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.

But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.

For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate.  Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.

These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

This moves aic79xx_pci_driver struct, removes some forward
declarations, and adds some ifdef CONFIG_PM.

b5720729f5 [SCSI] aic7xxx: Add suspend/resume support
The aic7xxx driver already contains fragments for suspend/resume
support. So we only need to update them to the current interface
and have full PCI suspend/resume.

19966769f9 [SCSI] aic79xx: use dma_get_required_mask()
As originally noted by Frederic Temporelli, the aic79xx supports 64
bit addressing, but the initialization code of the driver is wrong: it
tests the available memory size instead of testing the maximum
available memory address.

This patch uses the correct dma_get_required_mask() macros to
determine the correct addressing method.

97af50f60f [SCSI] aic7xxx/aic79xx: fix module removal path not to panic
In these drivers, scsi_remove_host() is called too late, at the point
it is called, the driver has already shut down too far to accept any
I/O that the shutdown might generate.  Any generated I/O actually
triggers a panic.

Fix this by calling scsi_remove_host() as early as possible and not
calling scsi_host_put() until just before we kfree the ahc_softc.

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!
