This patch increases size of driver internal response buffers. Some TPM
responses defined in TCG TPM Specification Version 1.2 Revision 103 have
increased size and do not fit previously defined buffers. Some TPM
responses do not have fixed size, so bigger response buffers have to be
allocated. 200B buffers should be enough.

The calgary code can give drivers addresses above 4GB which is very bad
for hardware that is only 32bit DMA addressable.
With this patch, the calgary code sets the global dma_ops to swiotlb or
nommu properly, and the dma_ops of devices behind the Calgary/CalIOC2
to calgary_dma_ops. So the calgary code can handle devices safely that
aren't behind the Calgary/CalIOC2.

Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
architecture does:
This enables us to cleanly fix the Calgary IOMMU issue that some devices
are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).
I think that per-device dma_mapping_ops support would be also helpful for
KVM people to support PCI passthrough but Andi thinks that this makes it
difficult to support the PCI passthrough (see the above thread). So I
CC'ed this to KVM camp. Comments are appreciated.
A pointer to dma_mapping_ops to struct dev_archdata is added. If the
pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's
NULL, the system-wide dma_ops pointer is used as before.
If it's useful for KVM people, I plan to implement a mechanism to register
a hook called when a new pci (or dma capable) device is created (it works
with hot plugging). It enables IOMMUs to set up an appropriate
dma_mapping_ops per device.
The major obstacle is that dma_mapping_error doesn't take a pointer to the
device unlike other DMA operations. So x86 can't have dma_mapping_ops per
device. Note all the POWER IOMMUs use the same dma_mapping_error function
so this is not a problem for POWER but x86 IOMMUs use different
dma_mapping_error functions.
The first patch adds the device argument to dma_mapping_error. The patch
is trivial but large since it touches lots of drivers and dma-mapping.h in
all the architecture.
This patch:
dma_mapping_error() doesn't take a pointer to the device unlike other DMA
operations. So we can't have dma_mapping_ops per device.
Note that POWER already has dma_mapping_ops per device but all the POWER
IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device
argument.

quirk_system_pci_resources() disables a PnP mem resource that overlaps a
PCI BAR so as to not keep the PCI driver from claiming the resource. Have
it do the same for io resources.
Here, ACPI claims ports that overlap with my soundcard causing the
soundcard driver to fail to load. It's unknown why my ACPI BIOS claims
those ports; it did not use to but this is not a (kernel) regression.
Some odd BIOS reconfig triggered by temporarily removing the card seems to
have brought this on.

dma_alloc_coherent() on x86 currently takes a passed in NULL device
pointer to mean that it should allocate an ISA compatible (24-bit) buffer
which is a bit of a hack.
The ALSA ISA drivers are the main consumers of this but have a struct
device in fact readily available.
For the legacy drivers, this sets the device dma_mask in preparation for
using the actual device with the DMA API so as to eventually not need the
NULL hack in dma_alloc_coherent().
This does not fix a current bug -- 2.6.26-rc1 stumbled over the NULL hack
in dma_alloc_coherent() but this has already been fixed in commit
4a367f3a9d by Takashi Iwai.

The ALSA ISA drivers are the main consumers of this but have a struct

For the PnP drivers, the specific pnp_dev->dev device pointer is not
always available at the right time so for now we want to pass the
pnp_card->dev instead which is always available. Set its dma_mask in
preparation for doing so.

The channel DIMM label does not seem to be used much in the edac code.
However, where it is used (in the core code), it is assumed to not have a
newline embedded. This leaves the sysfs file newline free which looks
funny when cat'ing it. Here we just add the trailing newline to the sysfs
chX_dimm_label output...
[Doug Thompson note: the DIMM label is one of the primary uses of EDAC.
User space daemon scripts, edac-utils@sourceforge, populate the DIMM label
fields, via /sys/devices/system/edac attributes, with the silk screen
labels of the motherboard in use. dmidecode access BIOS tables, but BIOS
tables are well known to be incorrect and useless in these respects.
edac-utils will strip off any newlines before its use of the output, when
displaying DIMM slot silk screen labels.
