The # TCB space for the HWCAP entries - which are created in pairs - is an ABI # extension, so waiting to create the space for HWCAP3 and HWCAP4 until # they are needed is problematic. Define AT_HWCAP3 and AT_HWCAP4 in the # generic uapi header so they can be used in glibc to reserve space in the # powerpc TCB for their future use. # # I scanned through the Linux and GLIBC source codes looking for unused # AT_* values and 29 and 30 did not seem to be used, so they are what I # went with. # # Signed-off-by: Peter Bergner # Acked-by: Adhemerval Zanella # Acked-by: Nicholas Piggin # Acked-by: Szabolcs Nagy # Acked-by: Arnd Bergmann # Signed-off-by: Michael Ellerman # Link: https://msgid.link/a406b535-dc55-4856-8ae9-5a063644a1af@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 3281366a8e79a512956382885091565db1036b64 # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_ge_imp3a_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/ge_imp3a_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_ge_imp3a_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_ge_imp3a_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_ge_imp3a_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/platforms/85xx/ge_imp3a.c:41:13: error: no previous prototype for 'ge_imp3a_pic_init' [-Werror=missing-prototypes] void __init ge_imp3a_pic_init(void) ^ cc1: error: unrecognized command line option '-Wno-shift-negative-value' [-Werror] cc1: all warnings being treated as errors make[6]: *** [/kisskb/src/scripts/Makefile.build:243: arch/powerpc/platforms/85xx/ge_imp3a.o] Error 1 make[5]: *** [/kisskb/src/scripts/Makefile.build:481: arch/powerpc/platforms/85xx] Error 2 make[4]: *** [/kisskb/src/scripts/Makefile.build:481: arch/powerpc/platforms] Error 2 make[4]: *** Waiting for unfinished jobs.... /kisskb/src/kernel/locking/spinlock.c:68:17: warning: no previous prototype for '__raw_spin_lock' [-Wmissing-prototypes] void __lockfunc __raw_##op##_lock(locktype##_t *lock) \ ^ /kisskb/src/kernel/locking/spinlock.c:126:1: note: in expansion of macro 'BUILD_LOCK_OPS' BUILD_LOCK_OPS(spin, raw_spinlock);
