With kuap on hash, segment interrupts are taken in # kernel often, which quickly breaks due to the missing restore. # # Signed-off-by: Nicholas Piggin # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200429065654.1677541-6-npiggin@gmail.com # < /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 25107dc0610d8687ebbf4fc56323babf87149cb4 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 40x/obs600_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_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/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' 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/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2598:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1859:6: warning: 'ret' 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] INFO: Uncompressed kernel (size 0x4fc3a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.7.0-rc2-g25107dc0610d Created: Wed May 6 16:00:59 2020 Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 2525398 Bytes = 2466.21 KiB = 2.41 MiB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 2518509 Bytes = 2459.48 KiB = 2.40 MiB Image 1: 2 Bytes = 0.00 KiB = 0.00 MiB Image 2: 6866 Bytes = 6.71 KiB = 0.01 MiB Completed OK # rm -rf /kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc4.6 # Build took: 0:00:44.850877
