Thus the # correct mask corresponding to XCR0 was not present in the core file for # GDB to interrogate, resulting in the following behavior: # # [kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core # Reading symbols from testsuite/outputs/gdb.base/corefile/corefile... # [New LWP 232880] # # warning: Unexpected size of section `.reg-xstate/232880' in core file. # # With the typo fixed, the test works again as expected. # # Signed-off-by: Kevin Buettner # Fixes: 9e4636545933 ("copy_xstate_to_kernel(): don't leave parts of destination uninitialized") # Cc: Al Viro # Cc: Dave Airlie # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 5714ee50bb4375bd586858ad800b1d9772847452 # < make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allnoconfig WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] # < make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] # make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] kernel: arch/sparc/boot/image is ready kernel: arch/sparc/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_sparc64-allnoconfig_sparc64 # Build took: 0:00:31.123204
