Therefore, being above the last standard clock # doesn't mean it is a bad clock. So, fallback to syscall instead # of returning -EINVAL inconditionaly. # # Fixes: e33ffc956b08 ("powerpc/vdso32: implement clock_getres entirely") # Cc: stable@vger.kernel.org # v5.6+ # Reported-by: Aurelien Jarno # Signed-off-by: Christophe Leroy # Signed-off-by: Michael Ellerman # Tested-by: Aurelien Jarno # Link: https://lore.kernel.org/r/7316a9e2c0c2517923eb4b0411c4a08d15e675a4.1589017281.git.christophe.leroy@csgroup.eu # < /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 e963b7a28b2bf2416304e1a15df967fcf662aff5 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc8540_ads_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1652:6: note: 'oldval' was declared here int oldval, ret; ^ INFO: Uncompressed kernel (size 0x4deb3c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4ce4ac) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.7.0-rc2-ge963b7a28b2b Created: Wed May 13 19:55:06 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2529022 Bytes = 2469.75 KiB = 2.41 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.7.0-rc2-ge963b7a28b2b Created: Wed May 13 19:55:06 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2559689 Bytes = 2499.70 KiB = 2.44 MiB Load Address: 00500000 Entry Point: 005002a4 Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 # Build took: 0:00:48.004572
