Add __cpuidle methods as noinstr to objtool's # noinstr detection and fix boatloads of cpuidle bugs & quirks. # # - Add new ABI: introduce MEMBARRIER_CMD_GET_REGISTRATIONS, to query # previously issued registrations. # # - Limit scheduler slice duration to the sysctl_sched_latency period, to # improve scheduling granularity with a large number of SCHED_IDLE # tasks. # # - Debuggability enhancement on sys_exit(): warn about disabled IRQs, # but also enable them to prevent a cascade of followup problems and # repeat warnings. # # - Fix the rescheduling logic in prio_changed_dl(). # # - Micro-optimize cpufreq and sched-util methods. # # - Micro-optimize ttwu_runnable() # # - Micro-optimize the idle-scanning in update_numa_stats(), # select_idle_capacity() and steal_cookie_task(). # # - Update the RSEQ code & self-tests # # - Constify various scheduler methods # # - Remove unused methods # # - Refine __init tags # # - Documentation updates # # - Misc other cleanups, fixes # # * tag 'sched-core-2023-02-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (110 commits) # sched/rt: pick_next_rt_entity(): check list_entry # sched/deadline: Add more reschedule cases to prio_changed_dl() # sched/fair: sanitize vruntime of entity being placed # sched/fair: Remove capacity inversion detection # sched/fair: unlink misfit task from cpu overutilized # objtool: mem*() are not uaccess safe # cpuidle: Fix poll_idle() noinstr annotation # sched/clock: Make local_clock() noinstr # sched/clock/x86: Mark sched_clock() noinstr # x86/pvclock: Improve atomic update of last_value in pvclock_clocksource_read() # x86/atomics: Always inline arch_atomic64*() # cpuidle: tracing, preempt: Squash _rcuidle tracing # cpuidle: tracing: Warn about !rcu_is_watching() # cpuidle: lib/bug: Disable rcu_is_watching() during WARN/BUG # cpuidle: drivers: firmware: psci: Dont instrument suspend code # KVM: selftests: Fix build of rseq test # exit: Detect and fix irq disabled state in oops # cpuidle, arm64: Fix the ARM64 cpuidle logic # cpuidle: mvebu: Fix duplicate flags assignment # sched/fair: Limit sched slice duration # ... # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/hppa-linux/bin/hppa64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/hppa-linux/bin/hppa64-linux-ld --version # < git log --format=%s --max-count=1 1f2d9ffc7a5f916935749ffc6e93fb33bfe94d2f # < make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/hppa-linux/bin/hppa64-linux- generic-64bit_defconfig # < make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/hppa-linux/bin/hppa64-linux- help # make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/hppa-linux/bin/hppa64-linux- olddefconfig # make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/hppa-linux/bin/hppa64-linux- In file included from /kisskb/src/include/linux/rculist.h:10, from /kisskb/src/include/linux/pid.h:5, from /kisskb/src/include/linux/sched.h:14, from /kisskb/src/fs/btrfs/volumes.c:6: /kisskb/src/fs/btrfs/volumes.c: In function 'btrfs_init_new_device': /kisskb/src/include/linux/list.h:74:12: warning: 'seed_devices' may be used uninitialized in this function [-Wmaybe-uninitialized] new->prev = prev; ~~~~~~~~~~^~~~~~ /kisskb/src/fs/btrfs/volumes.c:2612:27: note: 'seed_devices' was declared here struct btrfs_fs_devices *seed_devices; ^~~~~~~~~~~~ /kisskb/src/fs/btrfs/send.c: In function 'get_cur_inode_state': /kisskb/src/fs/btrfs/send.c:1909:13: warning: 'right_gen' may be used uninitialized in this function [-Wmaybe-uninitialized] } else if (right_gen == gen) { ^ Completed OK # rm -rf /kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 # Build took: 0:01:34.873193
