It used # to work (by chance ?) because CPU wake-up interrupt never comes from # user, so r2 is expected to point to 'current' on return. # # Commit e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access # Protection") broke it even more by clobbering r0 which is not # restored by fast_exception_return either. # # Use r6 instead of r0. This is possible because r3-r6 are restored by # fast_exception_return and only r3-r5 are used for exception arguments. # # For r2 it could be converted back to virtual address, but stay on the # safe side and restore it from the stack instead. It should be live # in the cache at that moment, so loading from the stack should make # no difference compared to converting it from phys to virt. # # Fixes: f7354ccac844 ("powerpc/32: Remove CURRENT_THREAD_INFO and rename TI_CPU") # Fixes: e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access Protection") # Cc: stable@vger.kernel.org # 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/6d02c3ae6ad77af34392e98117e44c2bf6d13ba1.1580121710.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 9933819099c4600b41a042f27a074470a43cf6b9 # < make -s -j 80 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 80 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 0x532f44) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x532f44) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x532f44) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x522848) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.5.0-rc5-g9933819099c4 Created: Thu Jan 30 01:32:39 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2691375 Bytes = 2628.30 KiB = 2.57 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.5.0-rc5-g9933819099c4 Created: Thu Jan 30 01:32:39 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2720383 Bytes = 2656.62 KiB = 2.59 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.5.0-rc5-g9933819099c4 Created: Thu Jan 30 01:32:39 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2721179 Bytes = 2657.40 KiB = 2.60 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.5.0-rc5-g9933819099c4 Created: Thu Jan 30 01:32:39 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2720381 Bytes = 2656.62 KiB = 2.59 MiB Load Address: 00600000 Entry Point: 006002a4 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 # Build took: 0:00:43.769004
