A future patch will reenable it at a later # stage once a workaround has been developed. # # Fixes: 012ae244845f ("powerpc/perf: Trace imc PMU functions") # Cc: stable@vger.kernel.org # v5.2+ # Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> # Tested-by: Hariharan T.S. <hari@linux.ibm.com> # [mpe: Add pr_info_once() so dmesg shows the PMU has been disabled] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191118034452.9939-1-maddy@linux.vnet.ibm.com # < /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 249fad734a25889a4f23ed014d43634af6798063 # < make -s -j 24 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 24 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
