In short, the hot-pluggable # memory is not accounted for while estimating the size of the usable # memory properties. # # The issue is addressed by calculating usable memory property size using # max hotplug address instead of the last online memory address. # # Fixes: 2377c92e37fe ("powerpc/kexec_file: fix FDT size estimation for kdump kernel") # Signed-off-by: Sourabh Jain # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20230131030615.729894-1-sourabhjain@linux.ibm.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 fc546faa559538fb312c77e055243ece18ab3288 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/currituck_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc5 # Build took: 0:01:53.271429
