This # leads save_nvgprs to skip saving them, and subsequent functions and # return from interrupt will think they are saved. # # This causes kernel branch-to-garbage debugging to not have correct # registers, can also cause userspace to have its registers clobbered # after a segfault. # # Fixes: f0f558b131 ("powerpc/mm: Preserve CFAR value on SLB miss caused by access to bogus address") # Cc: Paul Mackerras <paulus@ozlabs.org> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 9c1a41149230e5e2d48c8948943306b8c0c9f242 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc832x_rdb_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 83xx/mpc832x_rdb_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc832x_rdb_defconfig_powerpc 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:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): interrupts size is (4), expected multiple of 8 in /qe@e0100000/mdio@3120/ethernet-phy@0 arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): interrupts size is (4), expected multiple of 8 in /qe@e0100000/mdio@3120/ethernet-phy@4 INFO: Uncompressed kernel (size 0x58f0e0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x57ea34) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.16.0-rc2-g9c1a411 Created: Sat Mar 24 23:35:53 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2781513 Bytes = 2716.32 kB = 2.65 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.16.0-rc2-g9c1a411 Created: Sat Mar 24 23:35:53 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2758106 Bytes = 2693.46 kB = 2.63 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_mpc832x_rdb_defconfig_powerpc # Build took: 0:00:22.872448
