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-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 3bb61aa61828499a7d0f5e560051625fd02ae7e4 # < make -s -j 10 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n | make -s -j 10 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/sparc/include/asm/cmpxchg.h:7:0, from /kisskb/src/arch/sparc/include/asm/atomic_32.h:17, from /kisskb/src/arch/sparc/include/asm/atomic.h:7, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/linux/page_counter.h:5, from /kisskb/src/mm/memcontrol.c:25: /kisskb/src/mm/memcontrol.c: In function 'memcg_reparent_objcgs': /kisskb/src/arch/sparc/include/asm/cmpxchg_32.h:28:22: warning: value computed is not used [-Wunused-value] #define xchg(ptr,x) ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr)))) ^ /kisskb/src/mm/memcontrol.c:328:2: note: in expansion of macro 'xchg' xchg(&objcg->memcg, parent); ^ /kisskb/src/arch/sparc/include/asm/cmpxchg_32.h:28:22: warning: value computed is not used [-Wunused-value] #define xchg(ptr,x) ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr)))) ^ /kisskb/src/mm/memcontrol.c:335:3: note: in expansion of macro 'xchg' xchg(&iter->memcg, parent); ^ /kisskb/src/drivers/tty/serial/sunzilog.c:1128:13: warning: 'sunzilog_putchar' defined but not used [-Wunused-function] static void sunzilog_putchar(struct uart_port *port, int ch) ^ In file included from /kisskb/src/arch/sparc/include/asm/cmpxchg.h:7:0, from /kisskb/src/arch/sparc/include/asm/atomic_32.h:17, from /kisskb/src/arch/sparc/include/asm/atomic.h:7, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/lock.h:5, from /kisskb/src/arch/sparc/include/asm/bitops_32.h:102, from /kisskb/src/arch/sparc/include/asm/bitops.h:7, from /kisskb/src/include/linux/bitops.h:29, 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:13: /kisskb/src/fs/ocfs2/file.c: In function 'ocfs2_file_write_iter': /kisskb/src/arch/sparc/include/asm/cmpxchg_32.h:28:22: warning: value computed is not used [-Wunused-value] #define xchg(ptr,x) ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr)))) ^ /kisskb/src/fs/ocfs2/file.c:2419:3: note: in expansion of macro 'xchg' xchg(&iocb->ki_complete, saved_ki_complete); ^ /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
