Pull remoteproc updates from Bjorn Andersson: "This introduces a new "detached" state for remote processors that are deemed to be running at the time Linux boots and the infrastructure for "attaching" to these. It then introduces the support for performing this operation for the STM32 platform. The coredump functionality is moved out from the core file and gains support for an optional mode where the recovery phase awaits the notification from devcoredump that the dump should be released. This allows userspace to grab the coredump in scenarios where vmalloc space is too low for creating a complete copy of the coredump before handing this to devcoredump. A new character device based interface is introduced to allow tying the stoppage of a remote processor to the termination of a user space process. This is useful in situations when such process provides crucial resources/operations for the firmware running on the remote processor. The Texas Instrument K3 driver gains support for the C66x and C71x DSPs. Qualcomm remoteprocs gains support for stashing relocation information in IMEM, to aid post mortem debugging and the crash notification mechanism is generalized to be reusable in cases where loosely coupled drivers needs to know about the status of a remote processor. One such example is the IPA hardware block, which is jointly owned with the modem and migrated to this improved interface. It also introduces a number of bug fixes and debug improvements for the Qualcomm modem remoteproc driver. And it cleans up the inconsistent interface for remoteproc drivers to implement power management" * tag 'rproc-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (56 commits) remoteproc: core: Register the character device interface remoteproc: Add remoteproc character device interface remoteproc: kill IPA notify code net: ipa: new notification infrastructure remoteproc: k3-dsp: Add support for C71x DSPs dt-bindings: remoteproc: k3-dsp: Update bindings for C71x DSPs remoteproc: k3-dsp: Add support for L2RAM loading on C66x DSPs remoteproc: k3-dsp: Add a remoteproc driver of K3 C66x DSPs dt-bindings: remoteproc: Add bindings for C66x DSPs on TI K3 SoCs remoteproc: k3: Add TI-SCI processor control helper functions remoteproc: Introduce rproc_of_parse_firmware() helper dt-bindings: arm: keystone: Add common TI SCI bindings remoteproc: qcom_q6v5_mss: Remove redundant running state remoteproc: qcom: q6v5: Update running state before requesting stop remoteproc: qcom_q6v5_mss: Add modem debug policy support remoteproc: qcom_q6v5_mss: Validate modem blob firmware size before load remoteproc: qcom_q6v5_mss: Validate MBA firmware size before load rpmsg: update documentation remoteproc: qcom_q6v5_mss: Add MBA log extraction support remoteproc: Add coredump debugfs entry ...

Pull perf tools updates from Arnaldo Carvalho de Melo: "New features: - Introduce controlling how 'perf stat' and 'perf record' works via a control file descriptor, allowing starting with events configured but disabled until commands are received via the control file descriptor. This allows, for instance for tools such as Intel VTune to make further use of perf as its Linux platform driver. - Improve 'perf record' to to register in a perf.data file header the clockid used to help later correlate things like syslog files and perf events recorded. - Add basic syscall and find_next_bit benchmarks to 'perf bench'. - Allow using computed metrics in calculating other metrics. For instance: { .metric_expr = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit", .metric_name = "DCache_L2_All_Hits", }, { .metric_expr = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss", .metric_name = "DCache_L2_All_Miss", }, { .metric_expr = "dcache_l2_all_hits + dcache_l2_all_miss", .metric_name = "DCache_L2_All", } - Add suport for 'd_ratio', '>' and '<' operators to the expression resolver used in calculating metrics in 'perf stat'. Support for new kernel features: - Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope with things like ftrace, trampolines, i.e. changes in the kernel text that gets in the way of properly decoding Intel PT hardware traces, for instance. Intel PT: - Add various knobs to reduce the volume of Intel PT traces by reducing the level of details such as decoding just some types of packets (e.g., FUP/TIP, PSB+), also filtering by time range. - Add new itrace options (log flags to the 'd' option, error flags to the 'e' one, etc), controlling how Intel PT is transformed into perf events, document some missing options (e.g., how to synthesize callchains). BPF: - Properly report BPF errors when parsing events. - Do not setup side-band events if LIBBPF is not linked, fixing a segfault. Libraries: - Improvements to the libtraceevent plugin mechanism. - Improve libtracevent support for KVM trace events SVM exit reasons. - Add a libtracevent plugins for decoding syscalls/sys_enter_futex and for tlb_flush. - Ensure sample_period is set libpfm4 events in 'perf test'. - Fixup libperf namespacing, to make sure what is in libperf has the perf_ namespace while what is now only in tools/perf/ doesn't use that prefix. Arch specific: - Improve the testing of vendor events and metrics in 'perf test'. - Allow no ARM CoreSight hardware tracer sink to be specified on command line. - Fix arm_spe_x recording when mixed with other perf events. - Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of idle symbols. - List kernel supplied event aliases for arm64 in 'perf list'. - Add support for extended register capability in PowerPC 9 and 10. - Added nest IMC power9 metric events. Miscellaneous: - No need to setup sample_regs_intr/sample_regs_user for dummy events. - Update various copies of kernel headers, some causing perf to handle new syscalls, MSRs, etc. - Improve usage of flex and yacc, enabling warnings and addressing the fallout. - Add missing '--output' option to 'perf kmem' so that it can pass it along to 'perf record'. - 'perf probe' fixes related to adding multiple probes on the same address for the same event. - Make 'perf probe' warn if the target function is a GNU indirect function. - Remove //anon mmap events from 'perf inject jit' to fix supporting both using ELF files for generated functions and the perf-PID.map approaches" * tag 'perf-tools-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (144 commits) perf record: Skip side-band event setup if HAVE_LIBBPF_SUPPORT is not set perf tools powerpc: Add support for extended regs in power10 perf tools powerpc: Add support for extended register capability tools headers UAPI: Sync drm/i915_drm.h with the kernel sources tools arch x86: Sync asm/cpufeatures.h with the kernel sources tools arch x86: Sync the msr-index.h copy with the kernel sources tools headers UAPI: update linux/in.h copy tools headers API: Update close_range affected files perf script: Add 'tod' field to display time of day perf script: Change the 'enum perf_output_field' enumerators to be 64 bits perf data: Add support to store time of day in CTF data conversion perf tools: Move clockid_res_ns under clock struct perf header: Store clock references for -k/--clockid option perf tools: Add clockid_name function perf clockid: Move parse_clockid() to new clockid object tools lib traceevent: Handle possible strdup() error in tep_add_plugin_path() API libtraceevent: Fixed description of tep_add_plugin_path() API libtraceevent: Fixed type in PRINT_FMT_STING libtraceevent: Fixed broken indentation in parse_ip4_print_args() libtraceevent: Improve error handling of tep_plugin_add_option() API ...

Pull locking updates from Thomas Gleixner: "A set of locking fixes and updates: - Untangle the header spaghetti which causes build failures in various situations caused by the lockdep additions to seqcount to validate that the write side critical sections are non-preemptible. - The seqcount associated lock debug addons which were blocked by the above fallout. seqcount writers contrary to seqlock writers must be externally serialized, which usually happens via locking - except for strict per CPU seqcounts. As the lock is not part of the seqcount, lockdep cannot validate that the lock is held. This new debug mechanism adds the concept of associated locks. sequence count has now lock type variants and corresponding initializers which take a pointer to the associated lock used for writer serialization. If lockdep is enabled the pointer is stored and write_seqcount_begin() has a lockdep assertion to validate that the lock is held. Aside of the type and the initializer no other code changes are required at the seqcount usage sites. The rest of the seqcount API is unchanged and determines the type at compile time with the help of _Generic which is possible now that the minimal GCC version has been moved up. Adding this lockdep coverage unearthed a handful of seqcount bugs which have been addressed already independent of this. While generally useful this comes with a Trojan Horse twist: On RT kernels the write side critical section can become preemtible if the writers are serialized by an associated lock, which leads to the well known reader preempts writer livelock. RT prevents this by storing the associated lock pointer independent of lockdep in the seqcount and changing the reader side to block on the lock when a reader detects that a writer is in the write side critical section. - Conversion of seqcount usage sites to associated types and initializers" * tag 'locking-urgent-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (25 commits) locking/seqlock, headers: Untangle the spaghetti monster locking, arch/ia64: Reduce <asm/smp.h> header dependencies by moving XTP bits into the new <asm/xtp.h> header x86/headers: Remove APIC headers from <asm/smp.h> seqcount: More consistent seqprop names seqcount: Compress SEQCNT_LOCKNAME_ZERO() seqlock: Fold seqcount_LOCKNAME_init() definition seqlock: Fold seqcount_LOCKNAME_t definition seqlock: s/__SEQ_LOCKDEP/__SEQ_LOCK/g hrtimer: Use sequence counter with associated raw spinlock kvm/eventfd: Use sequence counter with associated spinlock userfaultfd: Use sequence counter with associated spinlock NFSv4: Use sequence counter with associated spinlock iocost: Use sequence counter with associated spinlock raid5: Use sequence counter with associated spinlock vfs: Use sequence counter with associated spinlock timekeeping: Use sequence counter with associated raw spinlock xfrm: policy: Use sequence counters with associated lock netfilter: nft_set_rbtree: Use sequence counter with associated rwlock netfilter: conntrack: Use sequence counter with associated spinlock sched: tasks: Use sequence counter with associated spinlock ...

Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two small interfaces: (a) GC_URGENT_LOW mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC mode allows Android to run some lower priority GCs in background, while new ioctl discards user information without race condition when the account is removed. In addition, some patches were merged to address latency-related issues. We've fixed some compression-related bug fixes as well as edge race conditions. Enhancements: - add GC_URGENT_LOW mode in gc_urgent - introduce F2FS_IOC_SEC_TRIM_FILE ioctl - bypass racy readahead to improve read latencies - shrink node_write lock coverage to avoid long latency Bug fixes: - fix missing compression flag control, i_size, and mount option - fix deadlock between quota writes and checkpoint - remove inode eviction path in synchronous path to avoid deadlock - fix to wait GCed compressed page writeback - fix a kernel panic in f2fs_is_compressed_page - check page dirty status before writeback - wait page writeback before update in node page write flow - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry We've added some minor sanity checks and refactored trivial code blocks for better readability and debugging information" * tag 'f2fs-for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (52 commits) f2fs: prepare a waiter before entering io_schedule f2fs: update_sit_entry: Make the judgment condition of f2fs_bug_on more intuitive f2fs: replace test_and_set/clear_bit() with set/clear_bit() f2fs: make file immutable even if releasing zero compression block f2fs: compress: disable compression mount option if compression is off f2fs: compress: add sanity check during compressed cluster read f2fs: use macro instead of f2fs verity version f2fs: fix deadlock between quota writes and checkpoint f2fs: correct comment of f2fs_exist_written_data f2fs: compress: delay temp page allocation f2fs: compress: fix to update isize when overwriting compressed file f2fs: space related cleanup f2fs: fix use-after-free issue f2fs: Change the type of f2fs_flush_inline_data() to void f2fs: add F2FS_IOC_SEC_TRIM_FILE ioctl f2fs: should avoid inode eviction in synchronous path f2fs: segment.h: delete a duplicated word f2fs: compress: fix to avoid memory leak on cc->cpages f2fs: use generic names for generic ioctls f2fs: don't keep meta inode pages used for compressed block migration ...

VDPA mlx5 accesses config space as native endian - this is wrong since it's a modern device and actually uses LE. It only supports modern guests so we could punt and just force LE, but let's use the full virtio APIs since people tend to copy/paste code, and this is not data path anyway. Signed-off-by:

The memory allocation failure checking for in and out is currently checking if the pointers are valid rather than the contents of what they point to. Hence the null check on failed memory allocations is incorrect. Fix this by adding the missing indirection in the check. Also for the default case, just set the *in and *out to null as these don't have any thing allocated to kfree. Finally remove the redundant *in and *out check as these have been already done on each allocation in the case statement.

Pull regset conversion fix from Al Viro: "Fix a regression from an unnoticed bisect hazard in the regset series. A bunch of old (aout, originally) primitives used by coredumps became dead code after fdpic conversion to regsets. Removal of that dead code had been the first commit in the followups to regset series; unfortunately, it happened to hide the bisect hazard on sh (extern for fpregs_get() had not been updated in the main series when it should have been; followup simply made fpregs_get() static). And without that followup commit this bisect hazard became breakage in the mainline" Tested-by:

To build host programs, you need to add the program names to 'hostprogs' to use the necessary build rule, but it is not enough to build them because there is no dependency. There are two types of host programs: built as the prerequisite of another (e.g. gen_crc32table in lib/Makefile), or always built when Kbuild visits the Makefile (e.g. genksyms in scripts/genksyms/Makefile). The latter is typical in Makefiles under scripts/, which contains host programs globally used during the kernel build. To build them, you need to add them to both 'hostprogs' and 'always-y'. This commit adds hostprogs-always-y as a shorthand. The same applies to user programs. net/bpfilter/Makefile builds bpfilter_umh on demand, hence always-y is unneeded. In contrast, programs under samples/ are added to both 'userprogs' and 'always-y' so they are always built when Kbuild visits the Makefiles. userprogs-always-y works as a shorthand. Signed-off-by:

The conditional: ifneq ($(hostprogs),) ... is evaluated to true if $(hostprogs) does not contain any word but whitespace characters. ifneq ($(strip $(hostprogs)),) ... is a safe way to avoid interpreting whitespace as a non-empty value, but I'd rather want to use the side-effect of $(sort ...) to do the equivalent. $(sort ...) is used in scripts/Makefile.host in order to drop duplication in $(hostprogs). It is also useful to strip excessive spaces. Move $(sort ...) before evaluating the ifneq. Signed-off-by:
