With kuap on hash, segment interrupts are taken in # kernel often, which quickly breaks due to the missing restore. # # Signed-off-by: Nicholas Piggin # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200429065654.1677541-6-npiggin@gmail.com # < /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 25107dc0610d8687ebbf4fc56323babf87149cb4 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 40x/obs600_defconfig # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:804: Warning: invalid register expression INFO: Uncompressed kernel (size 0x50a418) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.7.0-rc2-14556-g25107dc06 Created: Wed May 6 17:06:29 2020 Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 2577850 Bytes = 2517.43 KiB = 2.46 MiB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 2570961 Bytes = 2510.70 KiB = 2.45 MiB Image 1: 2 Bytes = 0.00 KiB = 0.00 MiB Image 2: 6866 Bytes = 6.71 KiB = 0.01 MiB Completed OK # rm -rf /kisskb/build/powerpc-fixes_40x_obs600_defconfig_powerpc-gcc5 # Build took: 0:01:00.677603
