Changes since v1: - implement __get_user_fn and __put_user_fn for the UACCESS_MEMCPY case and remove the small constant size optimizations in raw_copy_from_user and raw_copy_to_user - reshuffle the patch order a little Diffstat arch/riscv/Kconfig | 2 arch/riscv/include/asm/thread_info.h | 6 - arch/riscv/include/asm/uaccess.h | 177 +++++++++++++++++------------------ arch/riscv/kernel/process.c | 1 arch/riscv/lib/Makefile | 2 include/asm-generic/uaccess.h | 109 +++++++++++++-------- include/linux/uaccess.h | 4 7 files changed, 166 insertions(+), 135 deletions(-) _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
