A single larx/stcx. works fine, no need for the less # efficient cmpxchg sequence. # # Then remove the memory barriers from the operation. There is a # requirement for TLB flushing to load mm_cpumask after the store # that reduces pte permissions, which is moved into the TLB flush # code. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 c8635bc26fc137c218cba3b48a834a667e3ac790 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- ppc64le_defconfig # Added to kconfig CONFIG_KPROBES=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- /kisskb/src/arch/powerpc/kernel/stacktrace.c: In function 'save_stack_trace_tsk_reliable': /kisskb/src/arch/powerpc/kernel/stacktrace.c:176:28: error: 'kretprobe_trampoline' undeclared (first use in this function) if (ip == (unsigned long)kretprobe_trampoline) ^ /kisskb/src/arch/powerpc/kernel/stacktrace.c:176:28: note: each undeclared identifier is reported only once for each function it appears in /kisskb/src/scripts/Makefile.build:312: recipe for target 'arch/powerpc/kernel/stacktrace.o' failed make[2]: * [arch/powerpc/kernel/stacktrace.o] Error 1 make[2]: * Waiting for unfinished jobs.... /kisskb/src/Makefile:1060: recipe for target 'arch/powerpc/kernel' failed make[1]: * [arch/powerpc/kernel] Error 2 make[1]: * Waiting for unfinished jobs....
