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-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 e4b79900222b8cccd4da4a7a89581f0e1b764ed2 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_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 INFO: Uncompressed kernel (size 0x51796c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51796c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5072f8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51796c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51796c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.16.0-rc2-ge4b7990 Created: Wed Mar 14 20:44:33 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2541776 Bytes = 2482.20 kB = 2.42 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.16.0-rc2-ge4b7990 Created: Wed Mar 14 20:44:33 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2567562 Bytes = 2507.38 kB = 2.45 MB Load Address: 00600000 Entry Point: 00601350 Image Name: Linux-4.16.0-rc2-ge4b7990 Created: Wed Mar 14 20:44:33 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2567890 Bytes = 2507.71 kB = 2.45 MB Load Address: 00600000 Entry Point: 00601534 Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc # Build took: 0:00:36.320291
