Depending on the detection mode it # either warns and disables detection for the task or kills the task if # the mode is set to fatal" # # * tag 'x86-urgent-2020-04-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # KVM: VMX: Extend VMXs #AC interceptor to handle split lock #AC in guest # KVM: x86: Emulate split-lock access as a write in emulator # x86/split_lock: Provide handle_guest_split_lock() # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 4f8a3cc1183c442daee6cc65360e3385021131e4 # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_collie_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- collie_defconfig # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_collie_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- help # make -s -j 48 ARCH=arm O=/kisskb/build/linus_collie_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- olddefconfig # make -s -j 48 ARCH=arm O=/kisskb/build/linus_collie_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1652:6: note: 'oldval' was declared here int oldval, ret; ^ Completed OK # rm -rf /kisskb/build/linus_collie_defconfig_arm-gcc4.9 # Build took: 0:00:34.304670
