This leads to different definitions of SYS_pkey_* # as the ones in the pkey test header set numeric constants where as the # ones from syscall.h reuse __NR_pkey_*. The compiler complains about # redefinitions since they are different. # # This replaces SYS_pkey_* definitions with __NR_pkey_* such that the # definitions in both syscall.h and pkeys.h are alike. This way, if # syscall.h has to be included for compatibility reasons, builds will # still succeed. # # Fixes: 743f3544fffb ("selftests/powerpc: Add wrapper for gettid") # Reported-by: Sachin Sant # Suggested-by: David Laight # Suggested-by: Michael Ellerman # Signed-off-by: Sandipan Das # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/a4956d838bf59b0a71a2553c5ca81131ea8b49b9.1596561758.git.sandipan@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 a7aaa2f26bfd932a654706b19859e7adf802bee2 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64e_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0xc39158) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xd00000) Image Name: Linux-5.8.0-rc2-ga7aaa2f26bfd Created: Thu Aug 6 08:06:14 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 5109102 Bytes = 4989.36 KiB = 4.87 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc64e_defconfig_powerpc-gcc4.9 # Build took: 0:02:20.502935
