We're not quite ready to move to the recently added # generic functions yet, but the code here has been deliberately written # to mimic that closely so we can look at cleaning things up once we # have a bit more breathing room. # # Having said all that, the second version of these patches was posted # last week and I pushed it into our CI (kernelci and cki) along with a # commit which forced on PROVE_LOCKING, NOHZ_FULL and # CONTEXT_TRACKING_FORCE. The result? We found a real bug in the # md/raid10 code [3]. # # Oh, and there's also a really silly typo patch that's unrelated. # # Summary: # # - Fix numerous issues with instrumentation and exception entry # # - Fix hideous typo in unused register field definition" # # [1] https://lore.kernel.org/r/CACT4Y+aAzoJ48Mh1wNYD17pJqyEcDnrxGfApir=-j171TnQXhw@mail.gmail.com # [2] https://lore.kernel.org/r/20201119193819.GA2601289@elver.google.com # [3] https://lore.kernel.org/r/94c76d5e-466a-bc5f-e6c2-a11b65c39f83@redhat.com # # * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: # arm64: mte: Fix typo in macro definition # arm64: entry: fix EL1 debug transitions # arm64: entry: fix NMI {user, kernel}->kernel transitions # arm64: entry: fix non-NMI kernel<->kernel transitions # arm64: ptrace: prepare for EL1 irq/rcu tracking # arm64: entry: fix non-NMI user<->kernel transitions # arm64: entry: move el1 irq/nmi logic to C # arm64: entry: prepare ret_to_user for function call # arm64: entry: move enter_from_user_mode to entry-common.c # arm64: entry: mark entry code as noinstr # arm64: mark idle code as noinstr # arm64: syscall: exit userspace before unmasking exceptions # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 3bb61aa61828499a7d0f5e560051625fd02ae7e4 # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- FIT description: Linux 5.10.0-rc6-67058-g3bb61aa6182 Created: Thu Dec 3 09:48:24 2020 Image 0 (kernel@0) Description: Linux 5.10.0-rc6-67058-g3bb61aa6182 Created: Thu Dec 3 09:48:24 2020 Type: Kernel Image Compression: gzip compressed Data Size: 5177735 Bytes = 5056.38 KiB = 4.94 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x80985c58 Hash algo: sha1 Hash value: f4d0dcce076083236b521a24536f4d67a639c6d0 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Thu Dec 3 09:48:24 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Thu Dec 3 09:48:24 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Thu Dec 3 09:48:24 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 4659 Bytes = 4.55 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 5bcb6e4f21e8e5372544aa130b3bd097355a9050 Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Thu Dec 3 09:48:24 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 5418 Bytes = 5.29 KiB = 0.01 MiB Architecture: MIPS Hash algo: sha1 Hash value: 93d882f2009a217e0fa9dab94788535ed2be8476 Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Thu Dec 3 09:48:24 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/linus_mips-defconfig_mipsel # Build took: 0:02:44.360753
