Pull audit updates from Paul Moore: "We've got two audit patches for the v5.7 merge window with a stellar 14 lines changed between the two patches. The patch descriptions are far more lengthy than the patches themselves, which is a very good thing for patches this size IMHO. The patches pass our test suites and a quick summary is below: - Stop logging inode information when updating an audit file watch. Since we are not changing the inode, or the fact that we are watching the associated file, the inode information is just noise that we can do without. - Fix a problem where mandatory audit records were missing their accompanying audit records (e.g. SYSCALL records were missing). The missing records often meant that we didn't have the necessary context to understand what was going on when the event occurred" * tag 'audit-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: trigger accompanying records when no rules present audit: CONFIG_CHANGE don't log internal bookkeeping as an event

Pull gfs2 updates from Bob Peterson: "We've got a lot of patches (39) for this merge window. Most of these patches are related to corruption that occurs when journals are replayed. For example: 1. A node fails while writing to the file system. 2. Other nodes use the metadata that was once used by the failed node. 3. When the node returns to the cluster, its journal is replayed, but the older metadata blocks overwrite the changes from step 2. Summary: - Fixed the recovery sequence to prevent corruption during journal replay. - Many bug fixes found during recovery testing. - New improved file system withdraw sequence. - Fixed how resource group buffers are managed. - Fixed how metadata revokes are tracked and written. - Improve processing of IO errors hit by daemons like logd and quotad. - Improved error checking in metadata writes. - Fixed how qadata quota data structures are managed" * tag 'gfs2-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: (39 commits) gfs2: Fix oversight in gfs2_ail1_flush gfs2: change from write to read lock for sd_log_flush_lock in journal replay gfs2: instrumentation wrt ail1 stuck gfs2: don't lock sd_log_flush_lock in try_rgrp_unlink gfs2: Remove unnecessary gfs2_qa_{get,put} pairs gfs2: Split gfs2_rsqa_delete into gfs2_rs_delete and gfs2_qa_put gfs2: Change inode qa_data to allow multiple users gfs2: eliminate gfs2_rsqa_alloc in favor of gfs2_qa_alloc gfs2: Switch to list_{first,last}_entry gfs2: Clean up inode initialization and teardown gfs2: Additional information when gfs2_ail1_flush withdraws gfs2: leaf_dealloc needs to allocate one more revoke gfs2: allow journal replay to hold sd_log_flush_lock gfs2: don't allow releasepage to free bd still used for revokes gfs2: flesh out delayed withdraw for gfs2_log_flush gfs2: Do proper error checking for go_sync family of glops functions gfs2: Don't demote a glock until its revokes are written gfs2: drain the ail2 list after io errors gfs2: Withdraw in gfs2_ail1_flush if write_cache_pages fails gfs2: Do log_flush in gfs2_ail_empty_gl even if ail list is empty ...

Pull x86 timer updates from Thomas Gleixner: "A series of commits to make the MSR derived CPU and TSC frequency more accurate. It turned out that the frequency tables which have been taken from the SDM are inaccurate because the SDM provides truncated and rounded values, e.g. 83.3Mhz (83.3333...) or 116.7Mhz (116.6666...). This causes time drift in the range of ~1 second per hour (20-30 seconds per day). On some of these SoCs it's not possible to recalibrate the TSC because there is no reference (PIT, HPET) available. With some reverse engineering it was established that the possible frequencies are derived from the base clock with fixed multiplier / divider pairs. For the CPU models which have a known crystal frequency the kernel now uses multiplier / divider pairs which bring the frequencies closer to reality and fix the observed time drift issues" * tag 'x86-timers-2020-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc_msr: Make MSR derived TSC frequency more accurate x86/tsc_msr: Fix MSR_FSB_FREQ mask for Cherry Trail devices x86/tsc_msr: Use named struct initializers

Pull x86 splitlock updates from Thomas Gleixner: "Support for 'split lock' detection: Atomic operations (lock prefixed instructions) which span two cache lines have to acquire the global bus lock. This is at least 1k cycles slower than an atomic operation within a cache line and disrupts performance on other cores. Aside of performance disruption this is a unpriviledged form of DoS. Some newer CPUs have the capability to raise an #AC trap when such an operation is attempted. The detection is by default enabled in warning mode which will warn once when a user space application is caught. A command line option allows to disable the detection or to select fatal mode which will terminate offending applications with SIGBUS" * tag 'x86-splitlock-2020-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/split_lock: Avoid runtime reads of the TEST_CTRL MSR x86/split_lock: Rework the initialization flow of split lock detection x86/split_lock: Enable split lock detection by kernel

Pull timekeeping and timer updates from Thomas Gleixner: "Core: - Consolidation of the vDSO build infrastructure to address the difficulties of cross-builds for ARM64 compat vDSO libraries by restricting the exposure of header content to the vDSO build.

Pull irq updates from Thomas Gleixner: "Updates for the interrupt subsystem: Treewide: - Cleanup of setup_irq() which is not longer required because the memory allocator is available early. Most cleanup changes come through the various maintainer trees, so the final removal of setup_irq() is postponed towards the end of the merge window. Core: - Protection against unsafe invocation of interrupt handlers and unsafe interrupt injection including a fixup of the offending PCI/AER error injection mechanism. Invoking interrupt handlers from arbitrary contexts, i.e. outside of an actual interrupt, can cause inconsistent state on the fragile x86 interrupt affinity changing hardware trainwreck.

There's a semantic conflict in the Octeon staging network driver, which used the skb_reset_tc() function to reset skb state when re-using an skb. But that inline helper function was removed in mainline by commit 2c64605b ("net: Fix CONFIG_NET_CLS_ACT=n and CONFIG_NFT_FWD_NETDEV={y, m} build"). Fix it by using skb_reset_redirect() instead. Also move it out of the This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is enabled, which in turn only happens if you don't have CONFIG_NETFILTER configured. Which was how this wasn't caught by the usual allmodconfig builds.

Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - Various NUMA scheduling updates: harmonize the load-balancer and NUMA placement logic to not work against each other. The intended result is better locality, better utilization and fewer migrations. - Introduce Thermal Pressure tracking and optimizations, to improve task placement on thermally overloaded systems. - Implement frequency invariant scheduler accounting on (some) x86 CPUs. This is done by observing and sampling the 'recent' CPU frequency average at ~tick boundaries. The CPU provides this data via the APERF/MPERF MSRs. This hopefully makes our capacity estimates more precise and keeps tasks on the same CPU better even if it might seem overloaded at a lower momentary frequency. (As usual, turbo mode is a complication that we resolve by observing the maximum frequency and renormalizing to it.) - Add asymmetric CPU capacity wakeup scan to improve capacity utilization on asymmetric topologies.

Pull EFI updates from Ingo Molnar: "The EFI changes in this cycle are much larger than usual, for two (positive) reasons: - The GRUB project is showing signs of life again, resulting in the introduction of the generic Linux/UEFI boot protocol, instead of x86 specific hacks which are increasingly difficult to maintain. There's hope that all future extensions will now go through that boot protocol. - Preparatory work for RISC-V EFI support. The main changes are: - Boot time GDT handling changes - Simplify handling of EFI properties table on arm64 - Generic EFI stub cleanups, to improve command line handling, file I/O, memory allocation, etc. - Introduce a generic initrd loading method based on calling back into the firmware, instead of relying on the x86 EFI handover protocol or device tree. - Introduce a mixed mode boot method that does not rely on the x86 EFI handover protocol either, and could potentially be adopted by other architectures (if another one ever surfaces where one execution mode is a superset of another) - Clean up the contents of 'struct efi', and move out everything that doesn't need to be stored there. - Incorporate support for UEFI spec v2.8A changes that permit firmware implementations to return EFI_UNSUPPORTED from UEFI runtime services at OS runtime, and expose a mask of which ones are supported or unsupported via a configuration table. - Partial fix for the lack of by-VA cache maintenance in the decompressor on 32-bit ARM. - Changes to load device firmware from EFI boot service memory regions - Various documentation updates and minor code cleanups and fixes" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) efi/libstub/arm: Fix spurious message that an initrd was loaded efi/libstub/arm64: Avoid image_base value from efi_loaded_image partitions/efi: Fix partition name parsing in GUID partition entry efi/x86: Fix cast of image argument efi/libstub/x86: Use ULONG_MAX as upper bound for all allocations efi: Fix a mistype in comments mentioning efivar_entry_iter_begin() efi/libstub: Avoid linking libstub/lib-ksyms.o into vmlinux efi/x86: Preserve %ebx correctly in efi_set_virtual_address_map() efi/x86: Ignore the memory attributes table on i386 efi/x86: Don't relocate the kernel unless necessary efi/x86: Remove extra headroom for setup block efi/x86: Add kernel preferred address to PE header efi/x86: Decompress at start of PE image load address x86/boot/compressed/32: Save the output address instead of recalculating it efi/libstub/x86: Deal with exit() boot service returning x86/boot: Use unsigned comparison for addresses efi/x86: Avoid using code32_start efi/x86: Make efi32_pe_entry() more readable efi/x86: Respect 32-bit ABI in efi32_pe_entry() efi/x86: Annotate the LOADED_IMAGE_PROTOCOL_GUID with SYM_DATA ...

Pull objtool updates from Ingo Molnar: "The biggest changes in this cycle were the vmlinux.o optimizations by Peter Zijlstra, which are preparatory and optimization work to run objtool against the much richer vmlinux.o object file, to perform new, whole-program section based logic. That work exposed a handful of problems with the existing code, which fixes and optimizations are merged here. The complete 'vmlinux.o and noinstr' work is still work in progress, targeted for v5.8. There's also assorted fixes and enhancements from Josh Poimboeuf. In particular I'd like to draw attention to commit 644592d3, which turns fatal objtool errors into failed kernel builds. This behavior is IMO now justified on multiple grounds (it's easy currently to not notice an essentially corrupted kernel build), and the commit has been in -next testing for several weeks, but there could still be build failures with old or weird toolchains.
