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-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 3bb61aa61828499a7d0f5e560051625fd02ae7e4 # < make -s -j 8 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # < make -s -j 8 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 8 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 8 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:25: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:37: LSE atomics not supported by binutils /kisskb/src/samples/seccomp/user-trap.c: In function 'send_fd': /kisskb/src/samples/seccomp/user-trap.c:50:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] ((int )CMSG_DATA(cmsg)) = fd; ^ /kisskb/src/samples/seccomp/user-trap.c: In function 'recv_fd': /kisskb/src/samples/seccomp/user-trap.c:83:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] return ((int )CMSG_DATA(cmsg)); ^ Completed OK # rm -rf /kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 # Build took: 0:37:50.401946
