This is now replaced with more precise # arithmetics, using the new mul_u64_u64_div_u64() helper in math64.h. # # - Improve the deadline scheduler, such as making it capacity aware # # - Improve frequency-invariant scheduling # # - Misc cleanups in energy/power aware scheduling # # - Add sched_update_nr_running tracepoint to track changes to nr_running # # - Documentation additions and updates # # - Misc cleanups and smaller fixes # # * tag 'sched-core-2020-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (54 commits) # sched/doc: Factorize bits between sched-energy.rst & sched-capacity.rst # sched/doc: Document capacity aware scheduling # sched: Document arch_scale_*_capacity() # arm, arm64: Fix selection of CONFIG_SCHED_THERMAL_PRESSURE # Documentation/sysctl: Document uclamp sysctl knobs # sched/uclamp: Add a new sysctl to control RT default boost value # sched/uclamp: Fix a deadlock when enabling uclamp static key # sched: Remove duplicated tick_nohz_full_enabled() check # sched: Fix a typo in a comment # sched/uclamp: Remove unnecessary mutex_init() # arm, arm64: Select CONFIG_SCHED_THERMAL_PRESSURE # sched: Cleanup SCHED_THERMAL_PRESSURE kconfig entry # arch_topology, sched/core: Cleanup thermal pressure definition # trace/events/sched.h: fix duplicated word # linux/sched/mm.h: drop duplicated words in comments # smp: Fix a potential usage of stale nr_cpus # sched/fair: update_pick_idlest() Select group with lowest group_util when idle_cpus are equal # sched: nohz: stop passing around unused "ticks" parameter. # sched: Better document ttwu() # sched: Add a tracepoint to track rq->nr_running # ... # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 e4cbce4d131753eca271d9d67f58c6377f27ad21 # < make -s -j 24 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 24 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 24 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 24 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/sparc/include/asm/bug.h:25:0, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/thread_info.h:12, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/sparc/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/include/linux/spinlock.h:51, from /kisskb/src/include/linux/seqlock.h:15, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/arch/sparc/vdso/vclock_gettime.c:16: /kisskb/src/include/linux/seqlock.h: In function 'write_seqcount_begin_nested': /kisskb/src/arch/sparc/include/asm/percpu_64.h:19:25: error: '__local_per_cpu_offset' undeclared (first use in this function) #define __my_cpu_offset __local_per_cpu_offset ^ /kisskb/src/include/asm-generic/bug.h:145:27: note: in definition of macro 'WARN_ON_ONCE' int __ret_warn_once = !!(condition);
