Pull clk updates from Stephen Boyd: "Here's a collection of largely clk driver updates. The usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip, but it feels pretty light on commits. There's only one real commit to the framework core and that's to consolidate code. Otherwise the diffstat is dominated by many Qualcomm clk driver patches that modernize the driver for the proper way of speciying clk parents. That's shifting data around, which could subtly break things so I'll be on the lookout for fixes. New Drivers: - Proper clk driver for Mediatek MT7621 SoCs - Support for the clock controller on the new Rockchip rk3568 Updates: - Simplify Zynq Kconfig dependencies - Use clk_hw pointers in socfpga driver - Cleanup parent data in qcom clk drivers - Some cleanups for rk3399 modularization - Fix reparenting of i.MX UART clocks by initializing only the ones associated to stdout - Correct the PCIE clocks for i.MX8MP and i.MX8MQ - Make i.MX LPCG and SCU clocks return on registering failure - Kernel doc fixes - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0 - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U - Sigma-delta modulation on Allwinner V3s audio PLL" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (82 commits) MAINTAINERS: add MT7621 CLOCK maintainer staging: mt7621-dts: use valid vendor 'mediatek' instead of invalid 'mtk' staging: mt7621-dts: make use of new 'mt7621-clk' clk: ralink: add clock driver for mt7621 SoC clk: uniphier: Fix potential infinite loop clk: qcom: rpmh: add support for SDX55 rpmh IPA clock clk: qcom: gcc-sdm845: get rid of the test clock clk: qcom: convert SDM845 Global Clock Controller to parent_data dt-bindings: clock: separate SDM845 GCC clock bindings clk: qcom: apss-ipq-pll: Add missing MODULE_DEVICE_TABLE clk: qcom: a53-pll: Add missing MODULE_DEVICE_TABLE clk: qcom: a7-pll: Add missing MODULE_DEVICE_TABLE dt: bindings: add mt7621-sysc device tree binding documentation dt-bindings: clock: add dt binding header for mt7621 clocks clk: samsung: Remove redundant dev_err calls clk: zynqmp: pll: add set_pll_mode to check condition in zynqmp_pll_enable clk: zynqmp: move zynqmp_pll_set_mode out of round_rate callback clk: zynqmp: Drop dependency on ARCH_ZYNQMP clk: zynqmp: Enable the driver if ZYNQMP_FIRMWARE is selected clk: qcom: gcc-sm8350: use ARRAY_SIZE instead of specifying num_parents ...

Pull io_uring updates from Jens Axboe: - Support for multi-shot mode for POLL requests - More efficient reference counting. This is shamelessly stolen from the mm side. Even though referencing is mostly single/dual user, the 128 count was retained to keep the code the same. Maybe this should/could be made generic at some point. - Removal of the need to have a manager thread for each ring. The manager threads only job was checking and creating new io-threads as needed, instead we handle this from the queue path. - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this thread is "just" a regular application thread, so no need to restrict use of it anymore. - Cleanup of how internal async poll data lifetime is managed. - Fix for syzbot reported crash on SQPOLL cancelation. - Make buffer registration more like file registrations, which includes flexibility in avoiding full set unregistration and re-registration. - Fix for io-wq affinity setting. - Be a bit more defensive in task->pf_io_worker setup. - Various SQPOLL fixes. - Cleanup of SQPOLL creds handling. - Improvements to in-flight request tracking. - File registration cleanups. - Tons of cleanups and little fixes * tag 'for-5.13/io_uring-2021-04-27' of git://git.kernel.dk/linux-block: (156 commits) io_uring: maintain drain logic for multishot poll requests io_uring: Check current->io_uring in io_uring_cancel_sqpoll io_uring: fix NULL reg-buffer io_uring: simplify SQPOLL cancellations io_uring: fix work_exit sqpoll cancellations io_uring: Fix uninitialized variable up.resv io_uring: fix invalid error check after malloc io_uring: io_sq_thread() no longer needs to reset current->pf_io_worker kernel: always initialize task->pf_io_worker to NULL io_uring: update sq_thread_idle after ctx deleted io_uring: add full-fledged dynamic buffers support io_uring: implement fixed buffers registration similar to fixed files io_uring: prepare fixed rw for dynanic buffers io_uring: keep table of pointers to ubufs io_uring: add generic rsrc update with tags io_uring: add IORING_REGISTER_RSRC io_uring: enumerate dynamic resources io_uring: add generic path for rsrc update io_uring: preparation for rsrc tagging io_uring: decouple CQE filling from requests ...

Pull scheduler updates from Ingo Molnar: - Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and debugfs interfaces to a unified debugfs interface. - Signals: Allow caching one sigqueue object per task, to improve performance & latencies. - Improve newidle_balance() irq-off latencies on systems with a large number of CPU cgroups. - Improve energy-aware scheduling - Improve the PELT metrics for certain workloads - Reintroduce select_idle_smt() to improve load-balancing locality - but without the previous regressions - Add 'scheduler latency debugging': warn after long periods of pending need_resched. This is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature, or the use of the resched_latency_warn_ms=xx boot parameter. - CPU hotplug fixes for HP-rollback, and for the 'fail' interface.

Pull perf event updates from Ingo Molnar: - Improve Intel uncore PMU support: - Parse uncore 'discovery tables' - a new hardware capability enumeration method introduced on the latest Intel platforms. This table is in a well-defined PCI namespace location and is read via MMIO. It is organized in an rbtree. These uncore tables will allow the discovery of standard counter blocks, but fancier counters still need to be enumerated explicitly. - Add Alder Lake support - Improve IIO stacks to PMON mapping support on Skylake servers - Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived) cores. The CPU-side feature set is entirely symmetrical - but on the PMU side there's core type dependent PMU functionality. - Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by fixing the AUX allocation watermark logic. - Improve ring buffer allocation on NUMA systems - Put 'struct perf_event' into their separate kmem_cache pool - Add support for synchronous signals for select perf events. The immediate motivation is to support low-overhead sampling-based race detection for user-space code. The feature consists of the following main changes: - Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits inheritance of events to CLONE_THREAD. - Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec. - Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64 ::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is PERF_TYPE_BREAKPOINT. The siginfo support is adequate for breakpoints right now - but the new field can be used to introduce support for other types of metadata passed over siginfo as well. - Misc fixes, cleanups and smaller updates. * tag 'perf-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) signal, perf: Add missing TRAP_PERF case in siginfo_layout() signal, perf: Fix siginfo_t by avoiding u64 on 32-bit architectures perf/x86: Allow for 8<num_fixed_counters<16 perf/x86/rapl: Add support for Intel Alder Lake perf/x86/cstate: Add Alder Lake CPU support perf/x86/msr: Add Alder Lake CPU support perf/x86/intel/uncore: Add Alder Lake support perf: Extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE perf/x86/intel: Add Alder Lake Hybrid support perf/x86: Support filter_match callback perf/x86/intel: Add attr_update for Hybrid PMUs perf/x86: Add structures for the attributes of Hybrid PMUs perf/x86: Register hybrid PMUs perf/x86: Factor out x86_pmu_show_pmu_cap perf/x86: Remove temporary pmu assignment in event_init perf/x86/intel: Factor out intel_pmu_check_extra_regs perf/x86/intel: Factor out intel_pmu_check_event_constraints perf/x86/intel: Factor out intel_pmu_check_num_counters perf/x86: Hybrid PMU support for extra_regs perf/x86: Hybrid PMU support for event constraints ...

Even though I'm sure the current code is ok, I totally dislike that s390 is the only architecture being special here; especially considering that there was a lengthly discussion about this topic and the outcome was not to use the builtins. Therefore open-code atomic ops again with inline assembly and switch to gcc builtins as soon as other architectures are doing. - couple of other changes to atomic and cmpxchg, and use atomic-instrumented.h for KASAN. - separate zbus creation, registration, and scanning in our PCI code which allows for cleaner and easier handling. - a rather large change to the vfio-ap code to fix circular locking dependencies when updating crypto masks. - move QAOB handling from qdio layer down to drivers. - add CRW inject facility to common I/O layer. This adds debugs files which allow to generate artificial events from user space for testing purposes. - increase SCLP console line length from 80 to 320 characters to avoid odd wrapped lines. - add protected virtualization guest and host indication files, which indicate either that a guest is running in pv mode or if the hypervisor is capable of starting pv guests. - various other small fixes and improvements all over the place. * tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (53 commits) s390/disassembler: increase ebpf disasm buffer size s390/archrandom: add parameter check for s390_arch_random_generate s390/zcrypt: fix zcard and zqueue hot-unplug memleak s390/pci: expose a PCI device's UID as its index s390/atomic,cmpxchg: always inline __xchg/__cmpxchg s390/smp: fix do_restart() prototype s390: get rid of oprofile leftovers s390/atomic,cmpxchg: make constraints work with old compilers s390/test_unwind: print test suite start/end info s390/cmpxchg: use unsigned long values instead of void pointers s390/test_unwind: add WARN if tests failed s390/test_unwind: unify error handling paths s390: update defconfigs s390/spinlock: use R constraint in inline assembly s390/atomic,cmpxchg: switch to use atomic-instrumented.h s390/cmpxchg: get rid of gcc atomic builtins s390/atomic: get rid of gcc atomic builtins s390/atomic: use proper constraints s390/atomic: move remaining inline assemblies to atomic_ops.h s390/bitops: make bitops only work on longs ...

It seems like Fedora 34 ends up enabling a few new gcc warnings, notably "-Wstringop-overread" and "-Warray-parameter". Both of them cause what seem to be valid warnings in the kernel, where we have array size mismatches in function arguments (that are no longer just silently converted to a pointer to element, but actually checked). This fixes most of the trivial ones, by making the function declaration match the function definition, and in the case of intel_pm.c, removing the over-specified array size from the argument declaration. At least one 'stringop-overread' warning remains in the i915 driver, but that one doesn't have the same obvious trivial fix, and may or may not actually be indicative of a bug. [ It was a mistake to upgrade one of my machines to Fedora 34 while being busy with the merge window, but if this is the extent of the compiler upgrade problems, things are better than usual - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Pull selinux updates from Paul Moore: - Add support for measuring the SELinux state and policy capabilities using IMA. - A handful of SELinux/NFS patches to compare the SELinux state of one mount with a set of mount options. Olga goes into more detail in the patch descriptions, but this is important as it allows more flexibility when using NFS and SELinux context mounts. - Properly differentiate between the subjective and objective LSM credentials; including support for the SELinux and Smack. My clumsy attempt at a proper fix for AppArmor didn't quite pass muster so John is working on a proper AppArmor patch, in the meantime this set of patches shouldn't change the behavior of AppArmor in any way. This change explains the bulk of the diffstat beyond security/. - Fix a problem where we were not properly terminating the permission list for two SELinux object classes. * tag 'selinux-pr-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: add proper NULL termination to the secclass_map permissions smack: differentiate between subjective and objective task credentials selinux: clarify task subjective and objective credentials lsm: separate security_task_getsecid() into subjective and objective variants nfs: account for selinux security context when deciding to share superblock nfs: remove unneeded null check in nfs_fill_super() lsm,selinux: add new hook to compare new mount to an existing mount selinux: fix misspellings using codespell tool selinux: fix misspellings using codespell tool selinux: measure state and policy capabilities selinux: Allow context mounts for unpriviliged overlayfs

Merge tag 'afs-netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull AFS updates from David Howells: "Use the new netfs lib. Begin the process of overhauling the use of the fscache API by AFS and the introduction of support for features such as Transparent Huge Pages (THPs). - Add some support for THPs, including using core VM helper functions to find details of pages. - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache as this handles THPs and doesn't require allocation of large bvec arrays. - Delegate address_space read/pre-write I/O methods for AFS to the netfs helper library. A method is provided to the library that allows it to issue a read against the server. This includes a change in use for PG_fscache (it now indicates a DIO write in progress from the marked page), so a number of waits need to be deployed for it. - Split the core AFS writeback function to make it easier to modify in future patches to handle writing to the cache. [This might feasibly make more sense moved out into my fscache-iter branch]. I've tested these with "xfstests -g quick" against an AFS volume (xfstests needs patching to make it work). With this, AFS without a cache passes all expected xfstests; with a cache, there's an extra failure, but that's also there before these patches. Fixing that probably requires a greater overhaul (as can be found on my fscache-iter branch, but that's for a later time). Thanks should go to Marc Dionne and Jeff Altman of AuriStor for exercising the patches in their test farm also" Link: https://lore.kernel.org/lkml/3785063.1619482429@warthog.procyon.org.uk/ * tag 'afs-netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Use the netfs_write_begin() helper afs: Use new netfs lib read helper API afs: Use the fs operation ops to handle FetchData completion afs: Prepare for use of THPs afs: Extract writeback extension into its own function afs: Wait on PG_fscache before modifying/releasing a page afs: Use ITER_XARRAY for writing afs: Set up the iov_iter before calling afs_extract_data() afs: Log remote unmarshalling errors afs: Don't truncate iter during data fetch afs: Move key to afs_read struct afs: Print the operation debug_id when logging an unexpected data version afs: Pass page into dirty region helpers to provide THP size afs: Disable use of the fscache I/O routines
