The # TCB space for the HWCAP entries - which are created in pairs - is an ABI # extension, so waiting to create the space for HWCAP3 and HWCAP4 until # they are needed is problematic. Define AT_HWCAP3 and AT_HWCAP4 in the # generic uapi header so they can be used in glibc to reserve space in the # powerpc TCB for their future use. # # I scanned through the Linux and GLIBC source codes looking for unused # AT_* values and 29 and 30 did not seem to be used, so they are what I # went with. # # Signed-off-by: Peter Bergner # Acked-by: Adhemerval Zanella # Acked-by: Nicholas Piggin # Acked-by: Szabolcs Nagy # Acked-by: Arnd Bergmann # Signed-off-by: Michael Ellerman # Link: https://msgid.link/a406b535-dc55-4856-8ae9-5a063644a1af@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 3281366a8e79a512956382885091565db1036b64 # make -s -j 40 ARCH=x86 O=/kisskb/build/powerpc-next_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # < make -s -j 40 ARCH=x86 O=/kisskb/build/powerpc-next_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 40 ARCH=x86 O=/kisskb/build/powerpc-next_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 40 ARCH=x86 O=/kisskb/build/powerpc-next_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_x86_64_defconfig_x86_64-gcc8 # Build took: 0:01:33.414822
