| * ftrace: disable tracing on acpi idle callsSteven Rostedt2008-07-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | The acpi idle waits calls local_irq_save and then uses mwait to go into idle. The tracer gets reenabled at local_irq_save but does not detect that the idle allows for wake ups. This patch adds code to disable the tracing when acpi puts the CPU to idle.

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.

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.

* | dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori2008-07-2634-107/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

For this driver it means calculating a desired amount of IO memory based on the current MTU and updating this value with the bus when MTU changes occur. Because DMA mappings can fail, we have added a bounce buffer for temporary cases where the driver can not map IO memory for the buffer pool. The following changes are made to enable the driver for CMO: * DMA mapping errors will not result in error messages if entitlement has been exceeded and resources were not available. * DMA mapping errors are handled gracefully, ibmveth_replenish_buffer_pool() is corrected to check the return from dma_map_single and fail gracefully. * The driver will have a get_desired_dma function defined to function in a CMO environment. * When the MTU is changed, the driver will update the device IO entitlement Signed-off-by: Robert Jennings <rcj@linux.vnet.ibm.com> Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Santiago Leon <santil@us.ibm.com> Acked-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an I2C device node does not specify an interrupt, the .irq member of the board_info struct was set to -1. This caused crashes on following irq_dispose_mappings. Leave it NO_IRQ as returned from irq_of_parse_and_map. (Suggesting -1 as 'i2c-no-irq' used to be a bug in linux/i2c.h.)

We have carried full support of those ancient images till this moment. Now the support is removed, well, not fully removed. Now UBI will support only _clean_ old images, which were cleanly detached last time (just before kernel upgrade). This is most likely the case. But we will not support unclean ancient images. Surprisingly, this allows us to remove a big chunk of legacy code. And the same should be true for downgrading: clean images should downgrade fine, but unclean ones will not.
