But at this point, when using VMAP stack the DATA MMU # translation has already been re-enabled, leading to deadlock. # # Don't use the physical address of the stack when # CONFIG_VMAP_STACK is set. # # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Reported-by: Guenter Roeck <linux@roeck-us.net> # Fixes: 028474876f47 ("powerpc/32: prepare for CONFIG_VMAP_STACK") # Tested-by: Guenter Roeck <linux@roeck-us.net> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/daeacdc0dec0416d1c587cc9f9e7191ad3068dc0.1581095957.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 d4bf905307a1c90a27714ff7a9fd29b0a2ceed98 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc8272_ads_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc8272_ads_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc8272_ads_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /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/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/ext4/extents.c: In function 'ext4_convert_unwritten_io_end_vec': /kisskb/src/fs/ext4/extents.c:5009:23: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /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/fs/io_uring.c: In function '__io_sqe_files_update.isra.74': /kisskb/src/fs/io_uring.c:5713:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x597c7c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5876d4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.5.0-gd4bf905307a1 Created: Sat Feb 8 23:59:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2853495 Bytes = 2786.62 KiB = 2.72 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.5.0-gd4bf905307a1 Created: Sat Feb 8 23:59:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2884247 Bytes = 2816.65 KiB = 2.75 MiB Load Address: 00600000 Entry Point: 00600888 Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc8272_ads_defconfig_powerpc-gcc4.6 # Build took: 0:00:53.509793
