This series fixes it. # # - Add for_each_cpu_andnot() and for_each_cpu_andnot() (Valentin # Schneider) # # Extends the API with one more function and applies it in sched/core. # # * tag 'bitmap-6.1-rc1' of https://github.com/norov/linux: (28 commits) # sched/core: Merge cpumask_andnot()+for_each_cpu() into for_each_cpu_andnot() # lib/test_cpumask: Add for_each_cpu_and(not) tests # cpumask: Introduce for_each_cpu_andnot() # lib/find_bit: Introduce find_next_andnot_bit() # cpumask: fix checking valid cpu range # lib/bitmap: add tests for for_each() loops # lib/find: optimize for_each() macros # lib/bitmap: introduce for_each_set_bit_wrap() macro # lib/find_bit: add find_next{,_and}_bit_wrap # cpumask: switch for_each_cpu{,_not} to use for_each_bit() # net: fix cpu_max_bits_warn() usage in netif_attrmask_next{,_and} # cpumask: add cpumask_nth_{,and,andnot} # lib/bitmap: remove bitmap_ord_to_pos # lib/bitmap: add tests for find_nth_bit() # lib: add find_nth{,_and,_andnot}_bit() # lib/bitmap: add bitmap_weight_and() # lib/bitmap: don't call __bitmap_weight() in kernel code # tools: sync find_bit() implementation # lib/find_bit: optimize find_next_bit() functions # lib/find_bit: create find_first_zero_bit_le() # ... # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 d4013bc4d49f6da8178a340348369bb9920225c9 # < make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- randconfig # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # < make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig .config:5460:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- /kisskb/src/drivers/infiniband/core/user_mad.c: In function 'ib_umad_write': /kisskb/src/drivers/infiniband/core/user_mad.c:564:50: error: array subscript 'struct ib_rmpp_mad[0]' is partly outside array bounds of 'unsigned char[140]' [-Werror=array-bounds] 564 | hdr_len = ib_get_mad_data_offset(rmpp_mad->mad_hdr.mgmt_class);
