[PATCH 0/9] riscv: improve self-protection

[Jisheng Zhang <jszhang3@mail.ustc.edu.cn>]

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
