git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this has been in multiple -next releases. There were a few late breaking fixes and small features that got added in the last couple days, but the whole set has received a build success notification from the kbuild robot. Change summary: - Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. - Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. - ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Highlights include: - Larger virtual address space on 64-bit server CPUs. By default we use a 128TB virtual address space, but a process can request access to the full 512TB by passing a hint to mmap(). - Support for the new Power9 "XIVE" interrupt controller. - TLB flushing optimisations for the radix MMU on Power9. - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface Architecture 2.0". - The ability to configure the mmap randomisation limits at build and runtime. - Several small fixes and cleanups to the kprobes code, as well as support for KPROBES_ON_FTRACE. - Major improvements to handling of system reset interrupts, correctly treating them as NMIs, giving them a dedicated stack and using a new hypervisor call to trigger them, all of which should aid debugging and robustness. - Many fixes and other minor enhancements.

Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers.

Pull networking fixes from David Miller: 1) The wireless rate info fix from Johannes Berg. 2) When a RAW socket is in hdrincl mode, we need to make sure that the user provided at least a minimally sized ipv4/ipv6 header.

This is because verifier marks register r2 as unknown value after #519 where r2 is a stack pointer and r1 holds a constant value.

2017-04-28bpf: provide a generic macro for percpu values for selftestsDaniel Borkmann2-17/+27
To overcome bugs as described and fixed in 89087c456fb5 ("bpf: Fix values type used in test_maps"), provide a generic BPF_DECLARE_PERCPU() and bpf_percpu() accessor macro for all percpu map values used in tests. Declaring variables works as follows (also works for structs): BPF_DECLARE_PERCPU(uint32_t, my_value); They can then be accessed normally as uint32_t type through: bpf_percpu(my_value, <cpu_nr>) For example: bpf_percpu(my_value, 0)++; Implicitly, we make sure that the passed type is allocated and aligned by gcc at least on a 8-byte boundary, so that it works together with the map lookup/update syscall for percpu maps. We use it as a usage example in test_maps, so that others are free to adapt this into their code when necessary.

An tracing instance has several of the same capabilities as the top level instance, but may be implemented slightly different. Instead of just writing tests that duplicat the same test cases of the top level instance, allow a test to be written for both the top level as well as for an instance. If a test case can be run in both the top level as well as in an tracing instance directory, then it should add a tag "# flags: instance" in the header of the test file. Then after all tests have run, any test that has an instance flag set, will run again within a tracing instance.
