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-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 5714ee50bb4375bd586858ad800b1d9772847452 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc40x_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc40x_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/linus_ppc40x_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/linus_ppc40x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:623: Warning: invalid register expression /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1623:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/zstd/compress.c: In function 'ZSTD_compressBlock_doubleFast': /kisskb/src/lib/zstd/compress.c:1393:1: warning: the frame size of 1384 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ INFO: Uncompressed kernel (size 0x5a2314) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5a2314) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.8.0-rc6-g5714ee50bb43 Created: Mon Jul 20 16:31:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2894450 Bytes = 2826.61 KiB = 2.76 MiB Load Address: 00600000 Entry Point: 00601750 Image Name: Linux-5.8.0-rc6-g5714ee50bb43 Created: Mon Jul 20 16:31:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2895416 Bytes = 2827.55 KiB = 2.76 MiB Load Address: 00600000 Entry Point: 0060198c Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.9 # Build took: 0:01:05.002440
