I did not try to # reproduce on powerpc, but looking at the code, the same should apply to # powerpc/cmm ever since it started using the balloon compaction # infrastructure (luckily just recently). # # In case we have to migrate a ballon page to a newpage of another zone, the # managed page count of both zones is wrong. Paired with memory offlining # (which will adjust the managed page count), we can trigger kernel crashes # and all kinds of different symptoms. # # Fix it by properly adjusting the managed page count when migrating if # the zone changed. # # We'll temporarily modify the totalram page count. If this ever becomes a # problem, we can fine tune by providing helpers that don't touch # the totalram pages (e.g., adjust_zone_managed_page_count()). # # Fixes: fe030c9b85e6 ("powerpc/pseries/cmm: Implement balloon compaction") # Signed-off-by: David Hildenbrand <david@redhat.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191216103058.4958-1-david@redhat.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 892db32b07b340b60492e8e543aedc039639eef1 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig configs/2006/11/29/pmac32_defconfigkexec # yes \n | make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:12:0, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:208:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:873:36: note: 'speaker_vol' was declared here struct snd_kcontrol *master_vol, *speaker_vol; ^ INFO: Uncompressed kernel (size 0x8dd1e8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Completed OK # rm -rf /kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 # Build took: 0:01:35.018689
