2010-03-12zlib: make new optimized inflate endian independentJoakim Tjernlund
Commit 6846ee5ca68d81e6baccf0d56221d7a00c1be18b ("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.

2010-03-12drivers/char/mmtimer.c: eliminate useless codeJulia Lawall
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.

2010-03-12dma-mapping: dma-mapping.h: add dma_set_coherent_maskFUJITA Tomonori
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.

That makes it difficult to implement the generic DMA API via the PCI bus specific DMA API.

2010-03-12dma-mapping: sparc: unify 32bit and 64bit dma_set_maskFUJITA Tomonori
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.

2010-03-12dma-mapping: frv: remove the obsolete and unnecessary DMA API commentsFUJITA Tomonori
pci_dma_sync_single was obsoleted long ago. All the comments are generic, not architecture specific, simply describes some of the DMA-API (and frv has the same comments in three files). Documentation/DMA-API.txt have more detailed descriptions. This removes the above obsolete and unnecessary DMA API comments. Let's describe the DMA API in only Documentation/DMA-API.txt.

2010-03-12dma-mapping.h: add the dma_unmap state APIFUJITA Tomonori
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.

2010-03-12pci-dma: add linux/pci-dma.h to linux/pci.hFUJITA Tomonori
All the architectures properly set NEED_DMA_MAP_STATE now so we can safely add linux/pci-dma.h to linux/pci.h and remove the linux/pci-dma.h inclusion in arch's asm/pci.h Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Arnd Bergmann <arnd@arndb.de> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
