[GIT,PULL] non-MM updates for 6.5-rc1

Linus, please merge these non-MM updates for 6.5-rc1, thanks. The following changes since commit 7877cb91f1081754a1487c144d85dc0d2e2e7fc4: Linux 6.4-rc4 (2023-05-28 07:49:00 -0400) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm tags/mm-nonmm-stable-2023-06-24-19-23 for you to fetch changes up to 4afc9a402aa3890885747b396c1adcd45f127665: kernel/time/posix-stubs.c: remove duplicated include (2023-06-23 17:04:05 -0700) ---------------------------------------------------------------- - Arnd Bergmann has fixed a bunch of -Wmissing-prototypes in top-level directories. - Douglas Anderson has added a new "buddy" mode to the hardlockup detector. It permits the detector to work on architectures which cannot provide the required interrupts, by having CPUs periodically perform checks on other CPUs. - Zhen Lei has enhanced kexec's ability to support two crash regions. - Petr Mladek has done a lot of cleanup on the hard lockup detector's Kconfig entries. - And the usual bunch of singleton patches in various places. ---------------------------------------------------------------- Alexey Dobriyan (2): add intptr_t include/linux/math.h: fix mult_frac() multiple argument evaluation bug Angus Chen (1): init: add bdev fs printk if mount_block_root failed Arnd Bergmann (15): mm: percpu: unhide pcpu_embed_first_chunk prototype mm: page_poison: always declare __kernel_map_pages() function mm: sparse: mark populate_section_memmap() static lib: devmem_is_allowed: include linux/io.h locking: add lockevent_read() prototype panic: hide unused global functions panic: make function declarations visible kunit: include debugfs header file init: consolidate prototypes in linux/init.h init: move cifs_root_data() prototype into linux/mount.h thread_info: move function declarations to linux/thread_info.h time_namespace: always provide arch_get_vdso_data() prototype for vdso kcov: add prototypes for helper functions decompressor: provide missing prototypes syscalls: add sys_ni_posix_timers prototype Azeem Shaikh (1): procfs: replace all non-returning strlcpy with strscpy Ben Dooks (1): devres: show which resource was invalid in __devm_ioremap_resource() Christoph Hellwig (1): squashfs: don't include buffer_head.h Colin Ian King (2): scripts/spelling.txt: add more spellings to spelling.txt ocfs2: remove redundant assignment to variable bit_off Douglas Anderson (23): watchdog/perf: define dummy watchdog_update_hrtimer_threshold() on correct config watchdog/perf: more properly prevent false positives with turbo modes watchdog/hardlockup: add comments to touch_nmi_watchdog() watchdog/perf: rename watchdog_hld.c to watchdog_perf.c watchdog/hardlockup: move perf hardlockup checking/panic to common watchdog.c watchdog/hardlockup: style changes to watchdog_hardlockup_check() / is_hardlockup() watchdog/hardlockup: add a "cpu" param to watchdog_hardlockup_check() watchdog/hardlockup: move perf hardlockup watchdog petting to watchdog.c watchdog/hardlockup: rename some "NMI watchdog" constants/function watchdog/hardlockup: have the perf hardlockup use __weak functions more cleanly watchdog/hardlockup: detect hard lockups using secondary (buddy) CPUs watchdog/perf: add a weak function for an arch to detect if perf can use NMIs arm64: enable perf events based hard lockup detector watchdog/hardlockup: keep kernel.nmi_watchdog sysctl as 0444 if probe fails watchdog/hardlockup: HAVE_NMI_WATCHDOG must implement watchdog_hardlockup_probe() watchdog/hardlockup: don't use raw_cpu_ptr() in watchdog_hardlockup_kick() watchdog/hardlockup: in watchdog_hardlockup_check() use cpumask_copy() watchdog/hardlockup: remove softlockup comment in touch_nmi_watchdog() watchdog/buddy: cleanup how watchdog_buddy_check_hardlockup() is called watchdog/buddy: don't copy the cpumask in watchdog_next_cpu() watchdog/buddy: simplify the dependency for HARDLOCKUP_DETECTOR_PREFER_BUDDY watchdog/hardlockup: move SMP barriers from common code to buddy code powerpc: move arch_trigger_cpumask_backtrace from nmi.h to irq.h Haifeng Xu (1): fork: optimize memcg_charge_kernel_stack() a bit Joseph Qi (2): ocfs2: correct return value of ocfs2_local_free_info() ocfs2: cleanup trace events Kees Cook (1): checkpatch: check for 0-length and 1-element arrays Lecopzer Chen (4): watchdog: remove WATCHDOG_DEFAULT watchdog/hardlockup: change watchdog_nmi_enable() to void watchdog/perf: adapt the watchdog_perf interface for async model arm64: add hw_nmi_get_sample_period for preparation of lockup detector Lukas Bulwahn (1): watchdog/hardlockup: fix typo in config HARDLOCKUP_DETECTOR_PREFER_BUDDY Petr Mladek (6): watchdog/hardlockup: sort hardlockup detector related config values a logical way watchdog/hardlockup: make the config checks more straightforward watchdog/hardlockup: declare arch_touch_nmi_watchdog() only in linux/nmi.h watchdog/hardlockup: make HAVE_NMI_WATCHDOG sparc64-specific watchdog/sparc64: define HARDLOCKUP_DETECTOR_SPARC64 watchdog/hardlockup: define HARDLOCKUP_DETECTOR_ARCH Pingfan Liu (1): watchdog/perf: ensure CPU-bound context when creating hardlockup detector event Prathu Baronia (1): kthread: fix spelling typo and grammar in comments Simon Horman (1): kexec: avoid calculating array size twice Vincent Whitchurch (1): squashfs: cache partial compressed blocks Yang Li (1): kernel/time/posix-stubs.c: remove duplicated include Zhen Lei (6): kexec: fix a memory leak in crash_shrink_memory() kexec: delete a useless check in crash_shrink_memory() kexec: clear crashk_res if all its memory has been released kexec: improve the readability of crash_shrink_memory() kexec: add helper __crash_shrink_memory() kexec: enable kexec_crash_size to support two crash kernel regions arch/Kconfig | 16 +- arch/alpha/kernel/osf_sys.c | 2 -
