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 ...

Pull networking fixes from David Miller: 1) Make sure SKB control block is in the proper state during IPSEC ESP-in-TCP encapsulation. From Sabrina Dubroca. 2) Various kinds of attributes were not being cloned properly when we build new xfrm_state objects from existing ones. Fix from Antony Antony. 3) Make sure to keep BTF sections, from Tony Ambardar. 4) TX DMA channels need proper locking in lantiq driver, from Hauke Mehrtens. 5) Honour route MTU during forwarding, always.

2020-09-28ARM: dts: bcm2835: Change firmware compatible from simple-bus to simple-mfdMaxime Ripard1-2/+2
The current binding for the RPi firmware uses the simple-bus compatible as a fallback to benefit from its automatic probing of child nodes. However, simple-bus also comes with some constraints, like having the ranges, our case. Let's switch to simple-mfd that provides the same probing logic without those constraints.

2020-09-24gpio/aspeed-sgpio: enable access to all 80 input & output sgpiosJeremy Kerr1-2/+3
Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines, corresponding to the 80 status bits available in hardware. Each of these lines can be configured as either an input or an output. However, each of these GPIOs is actually an input *and* an output; we actually have 80 inputs plus 80 outputs. This change expands the maximum number of GPIOs to 160; the lower half of this range are the input-only GPIOs, the upper half are the outputs. We fix the GPIO directions to correspond to this mapping. This also fixes a bug when setting GPIOs - we were reading from the input register, making it impossible to set more than one output GPIO.

2020-09-17ethtool: add and use message type for tunnel info replyMichal Kubecek1-0/+3
Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd field in genetlink header) for replies to tunnel info netlink request, i.e. the same value as the request have. This is a problem because we are using two separate enums for userspace to kernel and kernel to userspace message types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for kernel to userspace messages. As the tunnel info request reached mainline in 5.9 merge window, we should still be able to fix the reply message type without breaking backward compatibility.

The patch partially reverts some of the UAPI bits of the buffer cache management hints. Namely, the queue consistency (memory coherency) user-space hint because, as it turned out, the kernel implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT. The patch reverts both kernel and user space parts: removes the DMA consistency attr functions, rolls back changes to v4l2_requestbuffers, v4l2_create_buffers structures and corresponding UAPI functions (plus compat32 layer) and cleans up the documentation.

2020-09-08dt-bindings: crypto: sa2ul: fix a DT binding check warningTero Kristo1-1/+1
DT binding check produces a warning about bad cell size: Documentation/devicetree/bindings/crypto/ti,sa2ul.example.dt.yaml: example-0: crypto@4e00000:reg:0: [0, 81788928, 0, 4608] is too long From schema: python3.6/site-packages/dtschema/schemas/reg.yaml Fix this by reducing the address sizes for the example to 1 cell from current 2.
