Btw, there is a bunch of cleanups that would fit in nicely on top of this: - remove the unused __invoke_copy_from function - fold __get_user_check into get_user as it is the only caller - fold __get_user_nocheck into __get_user as it is the only caller - fold __put_user_check into put_user as it is the only caller - fold __put_user_nocheck into __put_user as it is the only caller - implement get_user in terms of __get_user to document the difference better and to remove __get_user_common - implement put_user in terms of __put_user to document the difference better and to remove __get_user_common - remove __put_user_unknown/__get_user_unknown and replace them with BUILD_BUG_ON() On Thu, Apr 01, 2021 at 02:56:33PM +0200, Thomas Bogendoerfer wrote: > This series replaces get_fs/set_fs and removes it from MIPS arch code. > > Changes in v3: > - use get_user/get_kernel_nofault for helper functions > > Changes in v2: > - added copy_from_kernel_nofault_allowed() for !EVA to restrict > access of __get/__put_kernel_nofault > - replaced __get_data macro by helper functions > - removed leftover set_fs calls in ftrace.c > - further cleanup uaccess.h > > Thomas Bogendoerfer (4): > MIPS: kernel: Remove not needed set_fs calls > MIPS: uaccess: Added __get/__put_kernel_nofault > MIPS: uaccess: Remove get_fs/set_fs call sites > MIPS: Remove get_fs/set_fs > > arch/mips/Kconfig | 1 - > arch/mips/include/asm/processor.h | 4 - > arch/mips/include/asm/thread_info.h | 6 - > arch/mips/include/asm/uaccess.h | 436 +++++++++++----------------- > arch/mips/kernel/access-helper.h | 18 ++ > arch/mips/kernel/asm-offsets.c | 1 - > arch/mips/kernel/ftrace.c | 8 - > arch/mips/kernel/process.c | 2 - > arch/mips/kernel/scall32-o32.S | 4 +- > arch/mips/kernel/traps.c | 105 +++---- > arch/mips/kernel/unaligned.c | 199 +++++-------- > arch/mips/lib/memcpy.S | 28 +- > arch/mips/lib/memset.S | 3 - > arch/mips/lib/strncpy_user.S | 48 +-- > arch/mips/lib/strnlen_user.S | 44 +-- > arch/mips/mm/Makefile | 4 + > arch/mips/mm/maccess.c | 10 + > 17 files changed, 357 insertions(+), 564 deletions(-) > create mode 100644 arch/mips/kernel/access-helper.h > create mode 100644 arch/mips/mm/maccess.c > > -- > 2.29.2 ---end quoted text---
