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/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < git log --format=%s --max-count=1 a2ccce2ddfec3972eb628de6aafe4910770ccb21 # < make -s -j 40 ARCH=arm64 O=/kisskb/build/powerpc-next_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 40 ARCH=arm64 O=/kisskb/build/powerpc-next_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] Completed OK # rm -rf /kisskb/build/powerpc-next_arm64-defconfig_arm64 # Build took: 0:01:47.243220
