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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 249fad734a25889a4f23ed014d43634af6798063 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_tqm8xx_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- tqm8xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_tqm8xx_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here WARNING: vmlinux.o(.text+0xbab4): Section mismatch in reference from the function mmu_mark_initmem_nx() to the function .init.text:mmu_mapin_ram_chunk() The function mmu_mark_initmem_nx() references the function __init mmu_mapin_ram_chunk().
