Since unsigned long is 64 bits, a # 64-bit load needs to be used to load it, unless an endianness specific # correction offset is added to access the desired subpart. In this # case there is no reason to _not_ use a 64 bit load though. # # Fixes: 6c85b7bc637b ("powerpc/kvm: Use UV_RETURN ucall to return to ultravisor") # Cc: stable@vger.kernel.org # v5.4+ # Signed-off-by: Marcus Comstedt # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20191215094900.46740-1-marcus@mc.pp.se # < /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 228b607d8ea1b7d4561945058d5692709099d432 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_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_pseries_defconfig_powerpc-gcc5 # Build took: 0:03:24.908000
