8eb6c6e3b9 [PATCH] powerpc: node-aware dma allocations
Make sure dma_alloc_coherent allocates memory from the local node.  This
is important on Cell where we avoid going through the slow cpu
interconnect.

Note:  I could only test this patch on Cell, it should be verified on
some pseries machine by those that have the hardware.

So the IOMMU table building code needs to match.

4c76e0bcde [PATCH] powerpc: pseries: Use generic dma-window parsing function
Change the pseries iommu init code to use the new of_parse_dma_window()
to parse the ibm,dma-window and ibm,my-dma-window properties of pci and
virtual device nodes.

Also, clean up vio_build_iommu_table() a little.

Tested on pseries, with both vio and pci devices.

dd721ffd95 [PATCH] powerpc: use a common vio_match_device routine
This requires the compatible properties having vaules that are empty
strings instead of just being empty properties.

e10fa77368 [PATCH] powerpc: use the device tree for the iSeries vio bus probe
As an added bonus, since every vio_dev now has a device_node
associated with it, hotplug now works.

7daa411b81 [PATCH] powerpc: IOMMU support for honoring dma_mask
Some devices don't support full 32-bit DMA address space, which we currently
assume. Add the required mask-passing to the IOMMU allocators.

312c004d36 [PATCH] driver core: replace "hotplug" by "uevent"
Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

143dcec2f7 [PATCH] ppc64: add MODALIAS= for vio bus
A non-broken udev would autoload also the drivers for devices on the
pseries vio bus, like ibmveth, ibmvscsic and hvsc.  This is similar to pci,
usb and ieee1394:

 /lib/modules/`uname -r`/modules.alias
alias vio:TvscsiSIBM,v-scsi* ibmvscsic
alias vio:TnetworkSIBM,l-lan* ibmveth
alias vio:Tserial-serverShvterm2* hvcs

/events/debug.00004.pci.add.1394:MODALIAS='pci:v00001014d00000188sv00000000sd00000000bc06sc04i0f'
/events/debug.00005.pci.add.1509:MODALIAS='pci:v00008086d00001229sv00001014sd000001FFbc02sc00i00'

340601043d powerpc: Add a shutdown member to vio_driver
Add a shutdown member to struct vio_driver. We also need vio_bus_shutdown()
which converts from struct device to struct vio_dev and knows how to extract
the struct vio_driver.

Original patch adjusted for different location of vio.c.

Merge arch/ppc64/kernel/vio.c into arch/powerpc/kernel/vio.c, update
the Makefiles to make it work, and make ARCH=ppc64 still work.

Michael's version put vio.c in arch/powerpc/sysedv but after consolting
Paulus, this one puts it in arch/powerpc/kernel.
