Because of commit bf794bf5 ("powerpc/kprobes: Fix kallsyms lookup across powerpc ABIv1 and ABIv2"), in ppc64 ABIv1, our perf command eliminates the need to use the prefix "." at the symbol name. But when the command "perf probe -a schedule" is executed on ppc64 ABIv1, it obtains two symbol address information through /proc/kallsyms, for example: cat /proc/kallsyms | grep -w schedule c000000000657020 T .schedule c000000000d4fdb8 D schedule The symbol "D schedule" is not a function symbol, and perf will print: "p:probe/schedule _text+13958584"Failed to write event: Invalid argument Therefore, when searching symbols from map and adding probe point for them, a symbol type check is added. If the type of symbol is not a function, skip it.

Pull ATA updates from Damien Le Moal: "A larger than usual set of changes for this cycle. The bulk of the changes are part of a rework of libata messages and debugging features from Hannes. In more detail, the changes are as follows. - Small code cleanups in the pata_ali driver (unnecessary variable initialization and simplified return statement, from Jason and Colin. - Switch to using struct_group() in the sata_fsl driver, from Kees. - Convert many sysfs attribute show functions to use sysfs_emit() instead of snprintf(), from me. - sata_dwc_460ex driver code cleanups, from Andy. - Improve DMA setup and remove superfluous error message in libahci_platform, from Andy - A small code cleanup in libata to use min() instead of open coding test, from Changcheng. - Rework of libata messages from Hannes. This is especially focused on replacing compile time defined debugging messages (DPRINTK() and VPRINTK()) with regular dynamic debugging messages (pr_debug()) and traceipoint events. Both libata-core and many drivers are updated to have a consistent debugging level control for all drivers. - Extend compile test support to as many drivers as possible in ATA Kconfig to improve compile test coverage, from me. - Fixes to avoid compile time warnings (W=1) and sparse warnings in sata_fsl and ahci_xgene drivers, from me. - Fix the interface of the read_id() port operation method to clarify that the data buffer passed as an argument is little endian. This avoids sparse warnings in the pata_netcell, pata_it821x, ahci_xgene, ahci_cevaxi and ahci_brcm drivers. From me. - Small code cleanup in the pata_octeon_cf driver, from Minghao. - Improved IRQ configuration code in pata_of_platform, from Lad. - Simplified implementation of __ata_scsi_queuecmd(), from Wenchao. - Debounce delay flag renaming, from Paul. - Add support for AMD A85 FCH (Hudson D4) AHCI adapters, from Paul" * tag 'ata-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata: (106 commits) ata: pata_ali: remove redundant return statement ata: ahci: Add support for AMD A85 FCH (Hudson D4) ata: libata: Rename link flag ATA_LFLAG_NO_DB_DELAY ata: libata-scsi: simplify __ata_scsi_queuecmd() ata: pata_of_platform: Use platform_get_irq_optional() to get the interrupt ata: pata_samsung_cf: add compile test support ata: pata_pxa: add compile test support ata: pata_imx: add compile test support ata: pata_ftide010: add compile test support ata: pata_cs5535: add compile test support ata: pata_octeon_cf: remove redundant val variable ata: fix read_id() ata port operation interface ata: ahci_xgene: use correct type for port mmio address ata: sata_fsl: fix cmdhdr_tbl_entry and prde struct definitions ata: sata_fsl: fix scsi host initialization ata: pata_bk3710: add compile test support ata: ahci_seattle: add compile test support ata: ahci_xgene: add compile test support ata: ahci_tegra: add compile test support ata: ahci_sunxi: add compile test support ...

Pull more ACPI updates from Rafael Wysocki: "The most significant item here is the Platform Firmware Runtime Update and Telemetry (PFRUT) support designed to allow certain pieces of the platform firmware to be updated on the fly, among other things. Also important is the e820 handling change on x86 that should work around PCI BAR allocation issues on some systems shipping since 2019. The rest is just a handful of assorted fixes and cleanups on top of the ACPI material merged previously. Specifics: - Add support for the the Platform Firmware Runtime Update and Telemetry (PFRUT) interface based on ACPI to allow certain pieces of the platform firmware to be updated without restarting the system and to provide a mechanism for collecting platform firmware telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang). - Ignore E820 reservations covering PCI host bridge windows on sufficiently recent x86 systems to avoid issues with allocating PCI BARs on systems where the E820 reservations cover the entire PCI host bridge memory window returned by the _CRS object in the system's ACPI tables (Hans de Goede). - Fix and clean up acpi_scan_init() (Rafael Wysocki). - Add more sanity checking to ACPI SPCR tables parsing (Mark Langsdorf). - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang). - Drop unnecessary "static" from the ACPI PCC address space handling driver added recently (kernel test robot)" * tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: PCC: pcc_ctx can be static ACPI: scan: Rename label in acpi_scan_init() ACPI: scan: Simplify initialization of power and sleep buttons ACPI: scan: Change acpi_scan_init() return value type to void ACPI: SPCR: check if table->serial_port.access_width is too wide ACPI: APD: Check for NULL pointer after calling devm_ioremap() x86/PCI: Ignore E820 reservations for bridge windows on newer systems ACPI: pfr_telemetry: Fix info leak in pfrt_log_ioctl() ACPI: pfr_update: Fix return value check in pfru_write() ACPI: tools: Introduce utility for firmware updates/telemetry ACPI: Introduce Platform Firmware Runtime Telemetry driver ACPI: Introduce Platform Firmware Runtime Update device driver efi: Introduce EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER and corresponding structures

Prior to Linux v5.4 devtmpfs used mount_single() which treats the given mount options as "remount" options, so it updates the configuration of the single super_block on each mount. Since that was changed, the mount options used for devtmpfs are ignored. This is a regression which affect systemd - which mounts devtmpfs with "-o mode=755,size=4m,nr_inodes=1m". This patch restores the "remount" effect by calling reconfigure_single() Fixes: d401727e ("devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()") Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Pull module updates from Luis Chamberlain: "The biggest change here is in-kernel support for module decompression. This change is being made to help support LSMs like LoadPin as otherwise it loses link between the source of kernel module on the disk and binary blob that is being loaded into the kernel. kmod decompression is still done by userspace even with this is done, both because there are no measurable gains in not doing so and as it adds a secondary extra check for validating the module before loading it into the kernel. The rest of the changes are minor, the only other change worth mentionin there is Jessica Yu is now bowing out of maintenance of modules as she's taking a break from work. While there were other changes posted for modules, those have not yet received much review of testing so I'm not yet comfortable in merging any of those changes yet." * 'modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module: fix signature check failures when using in-kernel decompression kernel: Fix spelling mistake "compresser" -> "compressor" MAINTAINERS: add mailing lists for kmod and modules module.h: allow #define strings to work with MODULE_IMPORT_NS module: add in-kernel support for decompressing MAINTAINERS: Remove myself as modules maintainer module: Remove outdated comment

Commit 2b3d0478 ("unicode: Add utf8-data module") changed the generated utf8data file from 'utf8data.h' to 'utf8data.c', but didn't change the comments or the .gitignore to match. The comments should be updated too, but at least they don't cause any visible breakage. But the gitignore file needs changing to avoid git complaining about untracked files.

Merge branch 'signal-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull signal/exit/ptrace updates from Eric Biederman: "This set of changes deletes some dead code, makes a lot of cleanups which hopefully make the code easier to follow, and fixes bugs found along the way. The end-game which I have not yet reached yet is for fatal signals that generate coredumps to be short-circuit deliverable from complete_signal, for force_siginfo_to_task not to require changing userspace configured signal delivery state, and for the ptrace stops to always happen in locations where we can guarantee on all architectures that the all of the registers are saved and available on the stack. Removal of profile_task_ext, profile_munmap, and profile_handoff_task are the big successes for dead code removal this round. A bunch of small bug fixes are included, as most of the issues reported were small enough that they would not affect bisection so I simply added the fixes and did not fold the fixes into the changes they were fixing. There was a bug that broke coredumps piped to systemd-coredump. I dropped the change that caused that bug and replaced it entirely with something much more restrained. Unfortunately that required some rebasing. Some successes after this set of changes: There are few enough calls to do_exit to audit in a reasonable amount of time. The lifetime of struct kthread now matches the lifetime of struct task, and the pointer to struct kthread is no longer stored in set_child_tid. The flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is removed. Issues where task->exit_code was examined with signal->group_exit_code should been examined were fixed. There are several loosely related changes included because I am cleaning up and if I don't include them they will probably get lost. The original postings of these changes can be found at: https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org https://lkml.kernel.org/r/87bl1kunjj.fsf@email.froward.int.ebiederm.org https://lkml.kernel.org/r/87r19opkx1.fsf_-_@email.froward.int.ebiederm.org I trimmed back the last set of changes to only the obviously correct once.

Pull tracing updates from Steven Rostedt: "New: - The Real Time Linux Analysis (RTLA) tool is added to the tools directory. - Can safely filter on user space pointers with: field.ustring ~ "match-string" - eprobes can now be filtered like any other event. - trace_marker(_raw) now uses stream_open() to allow multiple threads to safely write to it. Note, this could possibly break existing user space, but we will not know until we hear about it, and then can revert the change if need be. - New field in events to display when bottom halfs are disabled. - Sorting of the ftrace functions are now done at compile time instead of at bootup. Infrastructure changes to support future efforts: - Added __rel_loc type for trace events. Similar to __data_loc but the offset to the dynamic data is based off of the location of the descriptor and not the beginning of the event.

The cpumap is dummy, so no need to go on figuring out affinity.o This way we reduce the setup time for simple scenarios like: $ perf stat sleep 1 Acked-by: Andi Kleen <andi@firstfloor.org> Acked-by: Ian Rogers <irogers@google.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Needed to check if a cpu_map is dummy, i.e. not a cpu map at all, for pid monitoring scenarios. This probably needs to move to libperf, but since perf itself is the first and so far only user, leave it at tools/perf/util/.
