It substracts KERNELBASE from the address # of nap_save_msscr0 to access it. # # With CONFIG_VMAP_STACK enabled, data MMU translation has already been # re-enabled, so power_save_ppc32_restore() has to access # nap_save_msscr0 by its virtual address. # # Reported-by: Larry Finger <Larry.Finger@lwfinger.net> # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK") # Tested-by: Larry Finger <Larry.Finger@lwfinger.net> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/7bce32ccbab3ba3e3e0f27da6961bf6313df97ed.1581663140.git.christophe.leroy@c-s.fr # < /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 454099efd693c76a25d6326d2c5b1d7003b480f9 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 83xx/kmeter1_defconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_kmeter1_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:338:21: 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:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1836:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1749:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/bridge/br_netlink.c: In function 'br_process_vlan_info': /kisskb/src/net/bridge/br_netlink.c:571:6: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/io_uring.c: In function '__io_sqe_files_update.isra.81': /kisskb/src/fs/io_uring.c:5824:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x539928) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.6.0-rc2-g454099efd693 Created: Mon Feb 17 15:31:41 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2627228 Bytes = 2565.65 KiB = 2.51 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc-gcc4.6 # Build took: 0:01:28.790334
