These are on for-next. I had to fix up a handful of merge conflicts, so LMK if I made any mistakes.
From: Jisheng Zhang <jszhang@kernel.org> patch1 is a trivial improvement patch to move some functions to .init section Then following patches improve self-protection by: Marking some variables __ro_after_init Constifing some variables Enabling ARCH_HAS_STRICT_MODULE_RWX Jisheng Zhang (9): riscv: add __init section marker to some functions riscv: Mark some global variables __ro_after_init riscv: Constify sys_call_table riscv: Constify sbi_ipi_ops riscv: kprobes: Implement alloc_insn_page() riscv: bpf: Move bpf_jit_alloc_exec() and bpf_jit_free_exec() to core riscv: bpf: Avoid breaking W^X riscv: module: Create module allocations without exec permissions riscv: Set ARCH_HAS_STRICT_MODULE_RWX if MMU arch/riscv/Kconfig | 1 + arch/riscv/include/asm/smp.h | 4 ++-- arch/riscv/include/asm/syscall.h | 2 +- arch/riscv/kernel/module.c | 2 +- arch/riscv/kernel/probes/kprobes.c | 8 ++++++++ arch/riscv/kernel/sbi.c | 10 +++++----- arch/riscv/kernel/smp.c | 6 +++--- arch/riscv/kernel/syscall_table.c | 2 +- arch/riscv/kernel/time.c | 2 +- arch/riscv/kernel/traps.c | 2 +- arch/riscv/kernel/vdso.c | 4 ++-- arch/riscv/mm/init.c | 12 ++++++------ arch/riscv/mm/kasan_init.c | 6 +++--- arch/riscv/mm/ptdump.c | 2 +- arch/riscv/net/bpf_jit_comp64.c | 13 ------------- arch/riscv/net/bpf_jit_core.c | 14 ++++++++++++++ 16 files changed, 50 insertions(+), 40 deletions(-)
