That inline function was simply masking # out the value of r1. # # In that commit, it was changed to using current_stack_pointer() (since # renamed current_stack_frame()), which is a heavier function as it is # an outline assembly function which cannot be inlined and which reads # the content of the stack at 0(r1). # # Convert to using current_stack_pointer for geting r1 and masking out # its value to obtain the base address of the stack pointer as before. # # Fixes: 7306e83ccf5c ("powerpc: Don't use CURRENT_THREAD_INFO to find the stack") # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/a37e699e7ab897742c07b6838a08af33bc9217e3.1579849665.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 031d94b0f4799478367ec10babdd755123142ed6 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_52xx_lite5200b_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 52xx/lite5200b_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_52xx_lite5200b_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/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/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/io_uring.c: In function '__io_sqe_files_update.isra.83': /kisskb/src/fs/io_uring.c:5824:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x51fa4c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51fa4c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x50f400) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.6.0-rc2-g031d94b0f479 Created: Thu Feb 20 23:05:03 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2573719 Bytes = 2513.40 KiB = 2.45 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.6.0-rc2-g031d94b0f479 Created: Thu Feb 20 23:05:03 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2603425 Bytes = 2542.41 KiB = 2.48 MiB Load Address: 00600000 Entry Point: 00600278 Image Name: Linux-5.6.0-rc2-g031d94b0f479 Created: Thu Feb 20 23:05:03 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2603382 Bytes = 2542.37 KiB = 2.48 MiB Load Address: 00600000 Entry Point: 00600278 Completed OK # rm -rf /kisskb/build/powerpc-next_52xx_lite5200b_defconfig_powerpc-gcc4.6 # Build took: 0:00:53.411376
