From: Jisheng Zhang <jszhang@xxxxxxxxxx> Similar as other architectures such as arm64, x86 and so on, use offsets relative to the exception table entry values rather than absolute addresses for both the exception locationand the fixup. patch1 consolidates the __ex_table construction, it's a great code clean up even w/o the 2nd patch. patch2 does the real job. Since v1: - fix build error for NOMMU case, thank lkp@xxxxxxxxx Jisheng Zhang (2): riscv: consolidate __ex_table construction riscv: switch to relative exception tables arch/riscv/include/asm/Kbuild | 1 - arch/riscv/include/asm/extable.h | 25 ++++++++++++++++++++ arch/riscv/include/asm/futex.h | 12 +++------- arch/riscv/include/asm/uaccess.h | 40 +++++++++++--------------------- arch/riscv/lib/uaccess.S | 4 ++-- arch/riscv/mm/extable.c | 2 +- scripts/mod/modpost.c | 27 +++++++++++++++++++++ scripts/sorttable.c | 2 +- 8 files changed, 73 insertions(+), 40 deletions(-) create mode 100644 arch/riscv/include/asm/extable.h -- 2.33.0
