By the time mmu_cleanup_all runs it is too late to use # udbg_printf, and calling it will cause PS3 systems to hang. # # Remove all debugging statements from ps3_mm_region_destroy() and # ps3_mm_vas_destroy() and replace any error reporting with calls # to lv1_panic. # # With this change builds with 'DEBUG' defined will not cause kexec # reboots to hang, and builds with 'DEBUG' defined or not will end # in lv1_panic if an error is encountered. # # Signed-off-by: Geoff Levand # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/7325c4af2b4c989c19d6a26b90b1fec9c0615ddf.1589049250.git.geoff@infradead.org # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 b3fc0fe88c866051e7fdf92c0fc5dde74d7d501d # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_adder875_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- adder875_defconfig # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_adder875_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- help # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_adder875_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_adder875_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:72:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:471:21: note: 'pdeo' was declared here /kisskb/src/fs/namei.c: In function 'handle_dots': /kisskb/src/fs/namei.c:1805:10: warning: 'inode' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/namei.c:1805:10: warning: 'seq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/io_uring.c: In function '__io_sqe_files_update.isra.94': /kisskb/src/fs/io_uring.c:6701:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] Image Name: Linux-5.7.0-rc2-gb3fc0fe88c86 Created: Tue May 12 13:40:32 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1899914 Bytes = 1855.38 KiB = 1.81 MiB Load Address: 00400000 Entry Point: 004001dc Completed OK # rm -rf /kisskb/build/powerpc-next_adder875_defconfig_powerpc-gcc4.6 # Build took: 0:01:18.098824
