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-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 66763e9d1f6a8eda00da3a32c007b2af61412c10 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_canyonlands_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/canyonlands_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_canyonlands_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_canyonlands_defconfig_powerpc # Build took: 0:00:29.572020
