2020-10-13ACPI: HMAT: refactor hmat_register_target_device to hmem_register_deviceDan Williams
In preparation for exposing "Soft Reserved" memory ranges without an HMAT, move the hmem device registration to its own compilation unit and make the implementation generic. The generic implementation drops usage acpi_map_pxm_to_online_node() that was translating ACPI proximity domain values and instead relies on numa_map_to_online_node() to determine the numa node for the device.

2020-10-13x86/numa: cleanup configuration dependent command-line optionsDan Williams
Patch series "device-dax: Support sub-dividing soft-reserved ranges", v5. The device-dax facility allows an address range to be directly mapped through a chardev, or optionally hotplugged to the core kernel page allocator as System-RAM. It is the mechanism for converting persistent memory (pmem) to be used as another volatile memory pool i.e. the current Memory Tiering hot topic on linux-mm. In the case of pmem the nvdimm-namespace-label mechanism can sub-divide it, but that labeling mechanism is not available / applicable to soft-reserved ("EFI specific purpose") memory [3]. This series provides a sysfs-mechanism for the daxctl utility to enable provisioning of volatile-soft-reserved memory ranges. The motivations for this facility are: 1/ Allow performance differentiated memory ranges to be split between kernel-managed and directly-accessed use cases. 2/ Allow physical memory to be provisioned along performance relevant address boundaries. For example, divide a memory-side cache [4] along cache-color boundaries. 3/ Parcel out soft-reserved memory to VMs using device-dax as a security / permissions boundary [5]. Specifically I have seen people (ab)using memmap=nn!ss (mark System-RAM as Persistent Memory) just to get the device-dax interface on custom address ranges. A follow-on for the VM use case is to teach device-dax to dynamically allocate 'struct page' at runtime to reduce the duplication of 'struct page' space in both the guest and the host kernel for the same physical pages.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "There's quite a lot of code here, but much of it is due to the addition of a new PMU driver as well as some arm64-specific selftests which is an area where we've traditionally been lagging a bit. In terms of exciting features, this includes support for the Memory Tagging Extension which narrowly missed 5.9, hopefully allowing userspace to run with use-after-free detection in production on CPUs that support it. Work is ongoing to integrate the feature with KASAN for 5.11. Another change that I'm excited about (assuming they get the hardware right) is preparing the ASID allocator for sharing the CPU page-table with the SMMU. Those changes will also come in via Joerg with the IOMMU pull. We do stray outside of our usual directories in a few places, mostly due to core changes required by MTE. Although much of this has been Acked, there were a couple of places where we unfortunately didn't get any review feedback. Other than that, we ran into a handful of minor conflicts in -next, but nothing that should post any issues. Summary: - Userspace support for the Memory Tagging Extension introduced by Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11. - Selftests for MTE, Pointer Authentication and FPSIMD/SVE context switching. - Fix and subsequent rewrite of our Spectre mitigations, including the addition of support for PR_SPEC_DISABLE_NOEXEC. - Support for the Armv8.3 Pointer Authentication enhancements. - Support for ASID pinning, which is required when sharing page-tables with the SMMU. - MM updates, including treating flush_tlb_fix_spurious_fault() as a no-op. - Perf/PMU driver updates, including addition of the ARM CMN PMU driver and also support to handle CPU PMU IRQs as NMIs. - Allow prefetchable PCI BARs to be exposed to userspace using normal non-cacheable mappings. - Implementation of ARCH_STACKWALK for unwinding. - Improve reporting of unexpected kernel traps due to BPF JIT failure. - Improve robustness of user-visible HWCAP strings and their corresponding numerical constants. - Removal of TEXT_OFFSET. - Removal of some unused functions, parameters and prototypes. - Removal of MPIDR-based topology detection in favour of firmware description. - Cleanups to handling of SVE and FPSIMD register state in preparation for potential future optimisation of handling across syscalls. - Cleanups to the SDEI driver in preparation for support in KVM. - Miscellaneous cleanups and refactoring work" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (148 commits) Revert "arm64: initialize per-cpu offsets earlier" arm64: random: Remove no longer needed prototypes arm64: initialize per-cpu offsets earlier kselftest/arm64: Check mte tagged user address in kernel kselftest/arm64: Verify KSM page merge for MTE pages kselftest/arm64: Verify all different mmap MTE options kselftest/arm64: Check forked child mte memory accessibility kselftest/arm64: Verify mte tag inclusion via prctl kselftest/arm64: Add utilities and a test to validate mte memory perf: arm-cmn: Fix conversion specifiers for node type perf: arm-cmn: Fix unsigned comparison to less than zero arm64: dbm: Invalidate local TLB when setting TCR_EL1.HD arm64: mm: Make flush_tlb_fix_spurious_fault() a no-op arm64: Add support for PR_SPEC_DISABLE_NOEXEC prctl() option arm64: Pull in task_stack_page() to Spectre-v4 mitigation code KVM: arm64: Allow patching EL2 vectors even with KASLR is not enabled arm64: Get rid of arm64_ssbd_state KVM: arm64: Convert ARCH_WORKAROUND_2 to arm64_get_spectre_v4_state() KVM: arm64: Get rid of kvm_arm_have_ssbd() KVM: arm64: Simplify handling of ARCH_WORKAROUND_2 ...

2020-10-05ACPI: button: fix handling lid state changes when input device closeddmitry.torokhov@gmail.com
The original intent of 84d3f6b76447 was to delay evaluating lid state until all drivers have been loaded, with input device being opened from userspace serving as a signal for this condition. Let's ensure that state updates happen even if userspace closed (or in the future inhibited) input device. Note that if we go through suspend/resume cycle we assume the system has been fully initialized even if LID input device has not been opened yet. This has a side-effect of fixing access to input->users outside of input->mutex protections by the way of eliminating said accesses and using driver private flag.

2020-10-02ACPI / extlog: Check for RDMSR failureBen Hutchings
extlog_init() uses rdmsrl() to read an MSR, which on older CPUs provokes a error message at boot: unchecked MSR access error: RDMSR from 0x179 at rIP: 0xcd047307 (native_read_msr+0x7/0x40) Use rdmsrl_safe() instead, and return -ENODEV if it fails.

2020-10-02node: Add access1 class to represent CPU to memory characteristicsJonathan Cameron
New access1 class is nearly the same as access0, but always provides characteristics for CPUs to memory. The existing access0 class provides characteristics to nearest or direct connnect initiator which may be a Generic Initiator such as a GPU or network adapter. This new class allows thread placement on CPUs to be performed so as to give optimal access characteristics to memory, even if that memory is for example attached to a GPU or similar and only accessible to the CPU via an appropriate bus.

2020-10-02ACPI: HMAT: Fix handling of changes from ACPI 6.2 to ACPI 6.3Jonathan Cameron
In ACPI 6.3, the Memory Proximity Domain Attributes Structure changed substantially. One of those changes was that the flag for "Memory Proximity Domain field is valid" was deprecated. This was because the field "Proximity Domain for the Memory" became a required field and hence having a validity flag makes no sense. So the correct logic is to always assume the field is there. Current code assumes it never is. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2020-10-02ACPI: Let ACPI know we support Generic Initiator Affinity StructuresJonathan Cameron
Until we tell ACPI that we support generic initiators, it will have to operate in fall back domain mode and all _PXM entries should be on existing non GI domains. This patch sets the relevant OSC bit to make that happen. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2020-10-02ACPI: Support Generic Initiator only domainsJonathan Cameron
Generic Initiators are a new ACPI concept that allows for the description of proximity domains that contain a device which performs memory access (such as a network card) but neither host CPU nor Memory. This patch has the parsing code and provides the infrastructure for an architecture to associate these new domains with their nearest memory processing node.
