Double up some of the get_user() and related macros # to be able to take advantage of this extended GNU C extension. This # should help improve the generated code's performance for these accesses. # # Cc: Bill Wendling # Suggested-by: Linus Torvalds # Signed-off-by: Nick Desaulniers # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 865c50e1d279671728c2936cb7680eb89355eeea # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM=y # Added to kconfig CONFIG_KVM_BOOK3S_32=m # Added to kconfig # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4104:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1667:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ INFO: Uncompressed kernel (size 0x9314e8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xa00000) Completed OK # rm -rf /kisskb/build/linus_pmac32_defconfig+KVM_powerpc-gcc4.9 # Build took: 0:02:44.554666
