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 # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/a37e699e7ab897742c07b6838a08af33bc9217e3.1579849665.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 031d94b0f4799478367ec10babdd755123142ed6 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) INFO: Uncompressed kernel (size 0x5430a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5430a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5430a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5329a4) 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 23:57:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2719113 Bytes = 2655.38 KiB = 2.59 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.6.0-rc2-g031d94b0f479 Created: Thu Feb 20 23:57:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2748249 Bytes = 2683.84 KiB = 2.62 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.6.0-rc2-g031d94b0f479 Created: Thu Feb 20 23:57:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2749331 Bytes = 2684.89 KiB = 2.62 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.6.0-rc2-g031d94b0f479 Created: Thu Feb 20 23:57:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2748250 Bytes = 2683.84 KiB = 2.62 MiB Load Address: 00600000 Entry Point: 006002a4 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 # Build took: 0:00:47.184587
