* sparc: use sparc64 version of scatterlist.hRobert Reif2008-12-111-2/+2
| | | | | | | | | | | | | | | | Use sparc64 version of scatterlist.h. There are three main differences: dma_addr_t replaces __u32 dma_address replaces dvma_address dma_length replaces dvma_length dma_addr_t is a u32 on sparc32. Boot tested on sparc32.

* sparc: Kill now spurious includes of sbus.hDavid S. Miller2008-08-291-1/+0
| | | | | | | | In order to make this week I also had to add an include of linux/dma-mapping.h to asm/pci_32.h because drivers/pci/pci.c really depends upon getting this header somehow. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Remove generic SBUS probing layer.David S. Miller2008-08-291-23/+0
| | | | | | | The individual SBUS IOMMU arch code now sets the IOMMU information directly into the OF device objects. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill sbus_arch_preinit().David S. Miller2008-08-291-9/+3
| | | | | | | 32-bit sparc just needed it to register the ioport procfs bits, do this via an arch_initcall() instead. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill sbus_ioremap() and sbus_iounmap().David S. Miller2008-08-291-16/+0

* sparc: Remove SBUS layer resource and irq handling.David S. Miller2008-08-291-27/+0
| | | | | | | All the drivers use OF device objects now for this information. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill SBUS layer IRQ hooks.David S. Miller2008-08-291-53/+0
| | | | | | IRQs are obtained by drivers from the of_device struct. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make mmu_map_dma_area and mmu_unmap_dma_area take a device pointer.David S. Miller2008-08-291-2/+2
| | | | | | | This lets us kill this "map it in every IOMMU" crazy code, and also some of the final references to sbus_root. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Kill mmu_translate_dvma() usage.David S. Miller2008-08-291-35/+1
| | | | | | | | Just simply use virt_to_page() on the provided virtual address pointer. Kill #if 0'd code. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Move SBUS DMA attribute interfaces out of asm/sbus.hDavid S. Miller2008-08-291-1/+1
| | | | | | | | | This is in preparation for the subsequent asm/sbus.h removal. Also, make these routines take a "struct device" or no arguments, as appropriate. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Implement more generic dma_*() interfaces.David S. Miller2008-08-291-0/+2
| | | | | | | | | These dispatch to either PCI or SBUS routines based upon the device bus type. This will allow us to let SBUS drivers call these routines. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make mmu_{get,release}_*() take a struct device pointer.David S. Miller2008-08-291-13/+4

* sparc: Make SBUS DMA interfaces take struct device.David S. Miller2008-08-291-24/+19
| | | | | | | This is the first step in converting all the SBUS drivers over to generic dma_*(). Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make IOMMU and IO-UNIT init work with device nodes.David S. Miller2008-08-291-11/+6
| | | | | | | | | | | And stick the iommu archdata pointer into the generic OF device tree of_device struct as well. We still have to pass the sbus_bus object down into the routines so that the SBUS bus objects get the iommu cookies set properly. After drivers get converted to being pure OF drivers, that can go away. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: don't use asm/of_device.hStephen Rothwell2008-08-071-1/+1

* [SPARC64]: Fix of_iounmap() region release.David S. Miller2006-12-311-1/+1
| | | | | | | | | | We need to pass in the resource otherwise we cannot release the region properly. We must know whether it is an I/O or MEM resource. Spotted by Eric Brower. Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] unpaged: fix sound Bad page statesHugh Dickins2005-11-221-1/+1
| | | | | | | | | | | | | | | | | | Earlier I unifdefed PageCompound, so that snd_pcm_mmap_control_nopage and others can give out a 0-order component of a higher-order page, which won't be mistakenly freed when zap_pte_range unmaps it. But many Bad page states reported a PG_reserved was freed after all: I had missed that we need to say __GFP_COMP to get compound page behaviour. Some of these higher-order pages are allocated by snd_malloc_pages, some by snd_malloc_dev_pages; or if SBUS, by sbus_alloc_consistent - but that has no gfp arg, so add __GFP_COMP into its sparc32/64 implementations. I'm still rather puzzled that DRM seems not to need a similar change.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+731
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
