These patches have also been in -next for # almost a week, just to be sure. # # - Add logic for making some seccomp flags exclusive (Tycho) # # - Update selftests for exclusivity testing (Kees)" # # * tag 'seccomp-v5.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: # seccomp: Make NEW_LISTENER and TSYNC flags exclusive # selftests/seccomp: Prepare for exclusive seccomp flags # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 83a50840e72a5a964b4704fcdc2fbb2d771015ab # < make -s -j 10 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n | make -s -j 10 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- /kisskb/src/arch/xtensa/kernel/pci.c:45:32: warning: 'pci_ctrl_tail' defined but not used [-Wunused-variable] static struct pci_controller **pci_ctrl_tail = &pci_ctrl_head; ^ ./usr/include/asm/setup.h:17: userspace cannot reference function or variable defined in the kernel /kisskb/src/drivers/char/tpm/tpm2-cmd.c: In function 'tpm2_unseal_trusted': /kisskb/src/drivers/char/tpm/tpm2-cmd.c:670:2: warning: 'blob_handle' may be used uninitialized in this function [-Wmaybe-uninitialized] tpm2_flush_context(chip, blob_handle); ^ In file included from /kisskb/src/arch/xtensa/include/asm/atomic.h:21:0, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/atomic.h:5, from /kisskb/src/arch/xtensa/include/asm/bitops.h:222, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:12, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/ocfs2/file.c:27: /kisskb/src/fs/ocfs2/file.c: In function 'ocfs2_file_write_iter': /kisskb/src/arch/xtensa/include/asm/cmpxchg.h:140:3: warning: value computed is not used [-Wunused-value] ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr)))) ^ /kisskb/src/fs/ocfs2/file.c:2386:3: note: in expansion of macro 'xchg' xchg(&iocb->ki_complete, saved_ki_complete); ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
