So P4D entries are actually PGD entries, or vice versa. # # The other way to think of it is that the P4D is a single entry page # table below the PGD. Zero bits of the address are needed to index into # the P4D, therefore a P4D entry maps the same size address space as a PGD # entry. # # As explained in the previous commit, there are no huge page sizes # supported directly at the PGD level on 64-bit Book3S, so there are also # no huge page sizes supported at the P4D level. # # Therefore p4d_is_leaf() can never be true, so drop the definition and # fallback to the default implementation that always returns false. # # Signed-off-by: Michael Ellerman # < /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 0e7991d4acafa88d5771c0227971996c00a55325 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- g5_defconfig # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_g5_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-next_g5_defconfig_powerpc-gcc5 # Build took: 0:01:28.527073
