This unpleasant typo appeared while porting the driver from Freescale original sources, where anyone can easily find the correct version. Current incorrect version potentially can influence segment and merge handling in block subsystem via MMC request queue settings. Signed-off-by:

inflate_fast() can do either POST INC or PRE INC on its pointers walking the memory to decompress. Default is PRE INC. The sout pointer offset was miscalculated in one case as the calculation assumed sout was a char * This breaks inflate_fast() iff configured to do POST INC. Signed-off-by:

Commit 6846ee5c ("zlib: Fix build of powerpc boot wrapper") made the new optimized inflate only available on arch's that define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS. This patch will again enable the optimization for all arch's by defining our own endian independent version of unaligned access. As an added bonus, arch's that define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS do a plain load instead. Signed-off-by:

The ARM kernel decompressor wants to be able to relocate r/w data independently from the rest of the image, and we do this by ensuring that r/w data has global visibility. Define STATIC_RW_DATA to be empty to achieve this. Signed-off-by:

The variable x is initialized twice to the same (side effect-free) expression. Drop one initialization. A simplified version of the semantic match that finds this problem is: (http://coccinelle.lip6.fr/) // <smpl> @forall@ idexpression *x; identifier f!=ERR_PTR; @@ x = f(...) ... when != x ( x = f(...,<+...x...+>,...) | * x = f(...) ) // </smpl> Stefan observed: The next x = rb_entry(mn->next, struct mmtimer, list); is preceded by a test whether mn->next is NULL. Unless that test is redundant too, your patch fixes a potential NULL pointer dereference, introduced by commit cbacdd95 "SGI Altix mmtimer: allow larger number of timers per node" in 2.6.26.

Each PPS source can be registered/deregistered into the system by using special modules called "clients". They simply define the PPS sources' attributes and implement the time signal registration mechanism. This patch adds a special directory for such clients and adds a dummy client that can be useful to test system integrity on real systems.

This converts arm to the generic pci_set_dma_mask and pci_set_consistent_dma_mask (removes HAVE_ARCH_PCI_SET_DMA_MASK for dmabounce). Signed-off-by:

This converts powerpc to use the generic pci_set_dma_mask and pci_set_consistent_dma_mask (drivers/pci/pci.c). The generic pci_set_dma_mask does what powerpc's pci_set_dma_mask does. Unlike powerpc's pci_set_consistent_dma_mask, the gneric pci_set_consistent_dma_mask sets only coherent_dma_mask. It doesn't work for powerpc? pci_set_consistent_dma_mask API should set only coherent_dma_mask? Signed-off-by:

dma_set_coherent_mask corresponds to pci_set_consistent_dma_mask. This is necessary to move to the generic device model DMA API from the PCI bus specific API in the long term. dma_set_coherent_mask works in the exact same way that pci_set_consistent_dma_mask does. So this patch also changes pci_set_consistent_dma_mask to call dma_set_coherent_mask. Signed-off-by:

FUJITA Tomonori authored
This changes pci_set_dma_mask to call the generic DMA API, dma_set_mask. pci_set_dma_mask (in drivers/pci/pci.c) does the same things that dma_set_mask does on all the architectures that use pci_set_dma_mask; calls dma_supprted and sets dev->dma_mask. So we safely change pci_set_dma_mask to simply call dma_set_mask. Signed-off-by:

This converts Alpha to use include/linux/pci-dma-compat.h. Alpha is the only architecutre that implements the PCI DMA API in the own way. That makes it difficult to implement the generic DMA API via the PCI bus specific DMA API. The generic DMA API calls the PCI DMA API implementation in arch/alpha/kernel/pci_iommu.c on non Jensen systems. It calls the DMA API in arch/alpha/kernel/pci-noop.c on Jensen systems. Signed-off-by:

This patchset transforms the PCI DMA API into the generic device model. It's one of the reasons why we introduced the generic DMA API long ago; driver writers are always able to use the generic DMA API with any bus instead of using bus specific DMA APIs such as pci_map_single, sbus_map_single, etc (only two bus specific APIs exist now; pci and ssb). Some of the PCI DMA API are already implented on the top of the generic DMA API (include/asm-generic/pci-dma-compat.h). But there are some exceptions. This patchset finishes the transformation. This patch: sparc has two dma_set_mask implementations for 32bit and 64bit. They are same except for the error returned value. We can safely unify them since the error returned value doesn't matter as long as it is negative (as DMA-API.txt describes). This patch also changes dma_set_mask not to call pci_set_dma_mask. Instead, dma_set_mask does the same thing that pci_set_dma_mask does. This change enables ut to change pci_set_dma_mask to call dma_set_mask; we can implement pci_set_dma_mask as pci-dma-compat.h does. Signed-off-by:

Adds the following macros: DECLARE_DMA_UNMAP_ADDR(ADDR_NAME) DECLARE_DMA_UNMAP_LEN(LEN_NAME) dma_unmap_addr(PTR, ADDR_NAME) dma_unmap_addr_set(PTR, ADDR_NAME, VAL) dma_unmap_len(PTR, LEN_NAME) dma_unmap_len_set(PTR, LEN_NAME, VAL) The API corresponds to the pci_unmap state API. We'll move to this new generic API from the PCI specific API in the long term. As include/asm-generic/pci-dma-compat.h does, the pci_unmap API simply calls the new generic API for some time.
