| |
This patch removes the unused functions set_kernel_text_rw/ro. Currently, it is not being invoked from anywhere and no other architecture (except arm) uses this code. Even in ARM, these functions are not invoked from anywhere currently.
Fixes: d27c3c90817e ("riscv: add STRICT_KERNEL_RWX support")
