2009-11-27x86/amd-iommu: Use check_device for amd_iommu_dma_supportedJoerg Roedel
The check_device logic needs to include the dma_supported checks to be really sure. Merge the dma_supported logic into check_device and use it to implement dma_supported. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Make np-cache a global flagJoerg Roedel
The non-present cache flag was IOMMU local until now which doesn't make sense. Make this a global flag so we can remove the lase user of 'struct iommu' in the map/unmap path. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Reimplement flush_all_domains_on_iommu()Joerg Roedel
This patch reimplements the function flush_all_domains_on_iommu to use the global protection domain list. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Reimplement amd_iommu_flush_all_domains()Joerg Roedel
This patch reimplementes the amd_iommu_flush_all_domains function to use the global protection domain list instead of flushing every domain on every IOMMU. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Implement protection domain listJoerg Roedel
This patch adds code to keep a global list of all protection domains. This allows to simplify the resume code. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Remove iommu_flush_domain functionJoerg Roedel
This iommu_flush_tlb_pde function does essentially the same. So the iommu_flush_domain function is redundant and can be removed. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Use __iommu_flush_pages for tlb flushesJoerg Roedel
This patch re-implements iommu_flush_tlb functions to use the __iommu_flush_pages logic. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Make iommu_flush_pages aware of multiple IOMMUsJoerg Roedel
This patch extends the iommu_flush_pages function to flush the TLB entries on all IOMMUs the domain has devices on. This basically gives up the former assumption that dma_ops domains are only bound to one IOMMU in the system. For dma_ops domains this is still true but not for IOMMU-API managed domains. Giving this assumption up for dma_ops domains too allows code simplification. Further it splits out the main logic into a generic function which can be used by iommu_flush_tlb too. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Add function to complete a tlb flushJoerg Roedel
This patch adds a function to the AMD IOMMU driver which completes all queued commands an all IOMMUs a specific domain has devices attached on. This is required in a later patch when per-domain flushing is implemented. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Add per IOMMU reference countingJoerg Roedel
This patch adds reference counting for protection domains per IOMMU. This allows a smarter TLB flushing strategy. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Add an index field to struct amd_iommuJoerg Roedel
This patch adds an index field to struct amd_iommu which can be used to lookup it up in an array. This index will be used in struct protection_domain to keep track which protection domain has devices behind which IOMMU. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Update copyright headersJoerg Roedel
This patch updates the copyright headers in the relevant AMD IOMMU driver files to match the date of the latest changes. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-11-27x86/amd-iommu: Separate internal interface definitionsJoerg Roedel

2009-11-27hw-breakpoints: Use struct perf_event_attr to define user breakpointsFrederic Weisbecker
In-kernel user breakpoints are created using functions in which we pass breakpoint parameters as individual variables: address, length and type. Although it fits well for x86, this just does not scale across archictectures that may support this api later as these may have more or different needs. Pass in a perf_event_attr structure instead because it is meant to evolve as much as possible into a generic hardware breakpoint parameter structure.

2009-11-27powerpc/mm: Fix bug in gup_hugepd()David Gibson
Commit a4fe3ce7699bfe1bd88f816b55d42d8fe1dac655 introduced a new get_user_pages() path for hugepages on powerpc. Unfortunately, there is a bug in it's loop logic, which can cause it to overrun the end of the intended region. This came about by copying the logic from the normal page path, which assumes the address and end parameters have been pagesize aligned at the top-level. Since they're not *hugepage* size aligned, the simplistic logic could step over the end of the gup region without triggering the loop end condition. This patch fixes the bug by using the technique that the normal page path uses in levels above the lowest to truncate the ending address to something we know we'll match with.

2009-11-27powerpc/mm: Fix bug in pagetable cache cleanup with CONFIG_PPC_SUBPAGE_PROTDavid Gibson
Commit a0668cdc154e54bf0c85182e0535eea237d53146 cleans up the handling of kmem_caches for allocating various levels of pagetables. Unfortunately, it conflicts badly with CONFIG_PPC_SUBPAGE_PROT, due to the latter's cleverly hidden technique of adding some extra allocation space to the top level page directory to store the extra information it needs. Since that extra allocation really doesn't fit into the cleaned up page directory allocating scheme, this patch alters CONFIG_PPC_SUBPAGE_PROT to instead allocate its struct subpage_prot_table as part of the mm_context_t.

Explicitly mmap the UV chipset MMR address ranges used to access blade-local registers.

2009-11-26x86/hw-breakpoints: Don't lose GE flag while disabling a breakpointFrederic Weisbecker
When we schedule out a breakpoint from the cpu, we also incidentally remove the "Global exact breakpoint" flag from the breakpoint control register.

2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov
pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.
