Some module parameters with only one line have the '\n' at the end of the
description. This is not needed nor wanted as after the description the
type (i.e. int) is followed by a newline.
Some modules contain a multi-line description, these are not affected
by this patch.

The offset field of the scatterlist entry *after* the last valid scatterlist
entry was used instead of the first scatterlist entry (as was the intention
of this code).
This worked fine until the kzalloc of the sglist was replaced with kmalloc
and sg_init_table only zeroed the exact needed length. Apparently kzalloc
zeroes a bit more than is strictly necessary so the offset field was
always 0 in the past.
But now the offset field was suddenly random and this led to broken captures.

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.

Allocate zoran devices dynamically. Currently, the zr36067 driver
stores the device structures in a global array, with room for 4
devices. This makes the bss section very large (90 kB!), and given
that most users, I suspect, have only one zoran device, this is a
waste of kernel memory. Allocating the memory dynamically lets us use
only the amount of memory we need.

When saa7134_board_init2 runs, it immediately overwrites the current value
(set earlier from module parameter) of tuner_type with the static values,
and then does autodetection. This patch moves the tuner_addr copy to earlier
in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2.
Autodetection could still potentially change to the wrong tuner type, but it
is now possible to override the default type for the card again.
My card's tuner is configured with autodetection from eeprom, so I don't
need to manually set the tuner. I've checked that the autodetection still
works for my card.
