However, # if the store is wider than one byte and is to an unaligned address, # it is possible that the store operand overlaps a page boundary # and the exception occurred on the latter part of the store operand, # meaning that it would be possible to copy a few more bytes. Since # copy_to_user is generally expected to copy as much as possible, # it would be better to copy those extra few bytes. This adds code # to do that. Since this edge case is not performance-critical, # the code has been written to be compact rather than as fast as # possible. # # Signed-off-by: Paul Mackerras <paulus@ozlabs.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 a2ccce2ddfec3972eb628de6aafe4910770ccb21 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_PERF_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- powernv_defconfig # Added to kconfig CONFIG_PERF_EVENTS=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_PERF_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_PERF_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
