sparc64: Add ATU (new IOMMU) support
ATU (Address Translation Unit) is a new IOMMU in SPARC supported with Hypervisor IOMMU v2 APIs. Current SPARC IOMMU supports only 32bit address ranges and one TSB per PCIe root complex that has a 2GB per root complex DVMA space limit. The limit has become a scalability bottleneck nowadays that a typical 10G/40G NIC can consume 300MB-500MB DVMA space per instance. When DVMA resource is exhausted, devices will not be usable since the driver can't allocate DVMA. ATU removes bottleneck by allowing guest os to create IOTSB of size 32G (or more) with 64bit address ranges available in ATU HW. 32G is more than enough DVMA space to be shared by all PCIe devices under root complex contrast to 2G space provided by legacy IOMMU. ATU allows PCIe devices to use 64bit DMA addressing. Devices which choose to use 32bit DMA mask will continue to work with the existing legacy IOMMU.

sparc64: Prepare to move to more saner user copy exception handling.
The fixup helper function mechanism for handling user copy fault handling is not %100 accurrate, and can never be made so. We are going to transition the code to return the running return return length, which is always kept track in one or more registers of each of these routines. In order to convert them one by one, we have to allow the existing behavior to continue functioning. Therefore make all the copy code that wants the fixup helper to be used return negative one. After all of the user copy routines have been converted, this logic and the fixup helpers themselves can be removed completely. Signed-off-by: David S. Miller <davem@davemloft.net> |

sparc64: Setup a scheduling domain for highest level cache.
Individual scheduler domain should consist different hierarchy consisting of cores sharing similar property. Currently, no scheduler domain is defined separately for the cores that shares the last level cache. As a result, the scheduler fails to take advantage of cache locality while migrating tasks during load balancing. Here are the cpu masks currently present for sparc that are/can be used in scheduler domain construction. cpu_core_map : set based on the cores that shares l1 cache. core_core_sib_map : is set based on the socket id. The prior SPARC notion of socket was defined as highest level of shared cache. However, the MD record on T7 platforms now describes the CPUs that share the physical socket and this is no longer tied to shared cache. That's why a separate cpu mask needs to be created that truly represent highest level of shared cache for all platforms.

nmi_backtrace: add more trigger_*_cpu_backtrace() methods
Patch series "improvements to the nmi_backtrace code" v9. This patch series modifies the trigger_xxx_backtrace() NMI-based remote backtracing code to make it more flexible, and makes a few small improvements along the way. The motivation comes from the task isolation code, where there are scenarios where we want to be able to diagnose a case where some cpu is about to interrupt a task-isolated cpu. It can be helpful to see both where the interrupting cpu is, and also an approximation of where the cpu that is being interrupted is. The nmi_backtrace framework allows us to discover the stack of the interrupted cpu. I've tested that the change works as desired on tile, and build-tested x86, arm, mips, and sparc64. For x86 I confirmed that the generic cpuidle stuff as well as the architecture-specific routines are in the new cpuidle section. For arm, mips, and sparc I just build-tested it and made sure the generic cpuidle routines were in the new cpuidle section, but I didn't attempt to figure out which the platform-specific idle routines might be. That might be more usefully done by someone with platform experience in follow-up patches. This patch (of 4): Currently you can only request a backtrace of either all cpus, or all cpus but yourself. It can also be helpful to request a remote backtrace of a single cpu, and since we want that, the logical extension is to support a cpumask as the underlying primitive. This change modifies the existing lib/nmi_backtrace.c code to take a cpumask as its basic primitive, and modifies the linux/nmi.h code to use the new "cpumask" method instead. The existing clients of nmi_backtrace (arm and x86) are converted to using the new cpumask approach in this change. The other users of the backtracing API (sparc64 and mips) are converted to use the cpumask approach rather than the all/allbutself approach. The mips code ignored the "include_self" boolean but with this change it will now also dump a local backtrace if requested.

sparc64: Enable setting "relaxed ordering" in IOMMU mappings
Enable relaxed ordering for memory writes in IOMMU TSB entry from dma_4v_alloc_coherent(), dma_4v_map_page() and dma_4v_map_sg() when dma_attrs DMA_ATTR_WEAK_ORDERING is set. This requires PCI IOMMU I/O Translation Services version 2.0 API. Many PCIe devices allow enabling relaxed-ordering (memory writes bypassing other memory writes) for various DMA buffers. A notable exception is the Mellanox mlx4 IB adapter. Due to the nature of x86 HW this appears to have little performance impact there. On SPARC HW however, this results in major performance degradation getting only about 3Gbps. Enabling RO in the IOMMU entries corresponding to mlx4 data buffers increases the throughput to about 13 Gbps.

sparc64: Fix cpu_possible_mask if nr_cpus is set
If kernel boot parameter nr_cpus is set, it should define the number of CPUs that can ever be available in the system i.e. cpu_possible_mask. setup_nr_cpu_ids() overrides the nr_cpu_ids based on the cpu_possible_mask during kernel initialization. If cpu_possible_mask is not set based on the nr_cpus value, earlier part of the kernel would be initialized using nr_cpus value leading to a kernel crash. Set cpu_possible_mask based on nr_cpus value. Thus setup_nr_cpu_ids() becomes redundant and does not corrupt nr_cpu_ids value.

usercopy: fold builtin_const check into inline function
Instead of having each caller of check_object_size() need to remember to check for a const size parameter, move the check into check_object_size() itself. This actually matches the original implementation in PaX, though this commit cleans up the now-redundant builtin_const() calls in the various architectures.

ftrace: Remove CONFIG_HAVE_FUNCTION_GRAPH_FP_TEST from config
Make HAVE_FUNCTION_GRAPH_FP_TEST a normal define, independent from kconfig. This removes some config file pollution and simplifies the checking for the fp test.
