2008-07-26mm: speculative page referencesNick Piggin
If we can be sure that elevating the page_count on a pagecache page will pin it, we can speculatively run this operation, and subsequently check to see if we hit the right page rather than relying on holding a lock or otherwise pinning a reference to the page. This can be done if get_page/put_page behaves consistently throughout the whole tree (ie. if we "get" the page after it has been used for something else, we must be able to free it with a put_page). Actually, there is a period where the count behaves differently: when the page is free or if it is a constituent page of a compound page. We need an atomic_inc_not_zero operation to ensure we don't try to grab the page in either case. This patch introduces the core locking protocol to the pagecache (ie. adds page_cache_get_speculative, and tweaks some update-side code to make it work). Thanks to Hugh for pointing out an improvement to the algorithm setting page_count to zero when we have control of all references, in order to hold off speculative getters.

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.

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.

2008-07-25edac: core fix static to dynamic ksetArthur Jones
Static kobjects and ksets are not supported in Linux kernel. Convert the mc_kset from static to dynamic. This patch depends on my previous patch to remove the module parameter attributes from mc...

2008-07-25edac: core fix redundant sysfs controls to parametersArthur Jones
/sys/devices/system/edac/mc has a few files which are duplicated in /sys/module/edac_core/parameters. Now that all the functionality is duplicated between these two locations, we remove the former kobject attributes and update the documentation.

2008-07-25edac: core fix workq timerArthur Jones
When updating the edac_mc_poll_msec module parameter from the sysfs /sys/module/edac_core/parameters/edac_mc_poll_msec file, we don't update the workq timers. So that, if we move from a big poll time to a small one, the small one won't take effect until the big one has timed out. Here we provide a new module parameter set method to call out to the update routine. This brings the /sys/module/edac_core/parameters functionality up to that provided by the /sys/drivers/system/edac/mc sysfs module parameter files so that we can remove them or at least link to the /sys/module files...

2008-07-25edac: core fix to use dynamic kobjectArthur Jones
Static kobjects are not supported in linux kernel. Convert the edac_pci_top_main_kobj from static to dynamic. This avoids the double free of the edac_pci_top_main_kobj.name that we see on module reload of the e752x edac driver (and probably others as well). In addition Greg KH <greg@kroah.com> has pointed out that this code may be cleaned up significantly. I will look at that as a follow-on patch, for now, I just want the minimum fix to get this double-free oops bug squashed... Many thanks to Greg KH for his patience in showing me what the Documentation/kobject.txt already said (oops)...

2008-07-25edac: i5100: cleanupArthur Jones
Some code cleanliness issues found by Andrew Morton (thanks!) which should not affect functionality, but which should help make the code more maintainable. In particular, we now: * convert all #define's w/ a parameter to static inlines * use 1UL rather than 1ULL when calculating an unsigned long * use pci_disable_device The resulting code is tested and seems to work fine...

It is possible that the BIOS did not enable ECC at boot time. We check for that case and fail to load if it is true.

The error mask we use to trigger ECC notifications is missing many bits of interest. We add these bits here so that all possible ECC errors can be reported.
