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> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 e4b79900222b8cccd4da4a7a89581f0e1b764ed2 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_adder875_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- adder875_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_adder875_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/mpc8xx.c: In function 'mpc885_get_clock': /kisskb/src/arch/powerpc/boot/mpc8xx.c:27:26: warning: variable 'div' set but not used [-Wunused-but-set-variable] int mfi, mfn, mfd, pdf, div; ^ INFO: Uncompressed kernel (size 0x40d844) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x40d844) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.16.0-rc2-ge4b7990 Created: Wed Mar 14 22:54:49 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1969414 Bytes = 1923.26 kB = 1.88 MB Load Address: 00500000 Entry Point: 005001a8 Completed OK # rm -rf /kisskb/build/powerpc-fixes_adder875_defconfig_powerpc-5.3 # Build took: 0:01:10.380626
