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/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 5714ee50bb4375bd586858ad800b1d9772847452 # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/drivers/scsi/dc395x.c: In function '__dc395x_eh_bus_reset': /kisskb/src/drivers/scsi/dc395x.c:155:36: warning: value computed is not used [-Wunused-value] #define DC395x_read8(acb,address) (u8)(inb(acb->io_port_base + (address))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c:1197:2: note: in expansion of macro 'DC395x_read8' DC395x_read8(acb, TRM_S1040_SCSI_INTSTATUS); ^~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c: In function 'set_basic_config': /kisskb/src/drivers/scsi/dc395x.c:155:36: warning: value computed is not used [-Wunused-value] #define DC395x_read8(acb,address) (u8)(inb(acb->io_port_base + (address))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c:3489:2: note: in expansion of macro 'DC395x_read8' DC395x_read8(acb, TRM_S1040_SCSI_INTSTATUS); ^~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c: In function 'adapter_uninit_chip': /kisskb/src/drivers/scsi/dc395x.c:155:36: warning: value computed is not used [-Wunused-value] #define DC395x_read8(acb,address) (u8)(inb(acb->io_port_base + (address))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c:4435:2: note: in expansion of macro 'DC395x_read8' DC395x_read8(acb, TRM_S1040_SCSI_INTSTATUS); ^~~~~~~~~~~~ /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
