2008-07-26x86 calgary: fix handling of devices that aren't behind the CalgaryAlexis Bruemmer
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.

2008-07-26dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori
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.

2008-07-26pnp: have quirk_system_pci_resources() include io resourcesRene Herman
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.

2008-07-26isa: set 24-bit dma_mask for ISA devicesRene Herman
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 4a367f3a9dbf2e7ffcee4702203479809236ee6e by Takashi Iwai.

2008-07-26pnp: set the pnp_card dma_mask for use by ISAPnP cardsRene Herman
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 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. 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 4a367f3a9dbf2e7ffcee4702203479809236ee6e by Takashi Iwai.

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.

2008-07-26V4L/DVB (8496): saa7134: Copy tuner data earlier in init to avoid ↵Simon Arlott
overwriting manual tuner type 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.
