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 # Signed-off-by: Christophe Leroy # Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK") # Tested-by: Larry Finger # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/7bce32ccbab3ba3e3e0f27da6961bf6313df97ed.1581663140.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 454099efd693c76a25d6326d2c5b1d7003b480f9 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_akebono_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/akebono_defconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_akebono_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/akebono.dts:251.28-289.5: Warning (pci_bridge): /plb/pciex@10100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/akebono.dts:291.28-329.5: Warning (pci_bridge): /plb/pciex@20100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/akebono.dts:331.28-369.5: Warning (pci_bridge): /plb/pciex@18100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/akebono.dts:371.28-409.5: Warning (pci_bridge): /plb/pciex@28100000000: node name is not "pci" or "pcie" arch/powerpc/boot/dts/akebono.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_akebono_defconfig_powerpc-gcc5 # Build took: 0:01:24.188666
