AT_BASE_PLATFORM is an AUXV entry that we export to userspace for use when we're running in that mode, which tells userspace the "platform" string for the real CPU version, as opposed to the faked version. Although we don't support compat mode when using DT CPU features, and arguably don't need to set AT_BASE_PLATFORM, the existing cputable based code always sets it even when we're running bare metal. That means the lack of AT_BASE_PLATFORM is a user-visible artifact of the fact that the kernel is using DT CPU features, which we don't want. So set it in the DT CPU features code also. This results in eg: $ LD_SHOW_AUXV=1 /bin/true | grep "AT_.*PLATFORM" AT_PLATFORM: power9 AT_BASE_PLATFORM:power9 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 66763e9d1f6a8eda00da3a32c007b2af61412c10 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-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-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:220:9: 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:886:36: note: 'speaker_vol' was declared here struct snd_kcontrol *master_vol, *speaker_vol; ^ WARNING: modpost: Found 1 section mismatch(es).
