Subject: [RFC PATCH 3/4] module: Use linux/set_memory.h
This header always exists, so doesn't require an ifdef around its
inclusion. When CONFIG_ARCH_HAS_SET_MEMORY=y it includes the asm header,
otherwise it provides empty versions of the set_memory_xx() routines.
The usages of set_memory_xx() are still guarded by CONFIG_STRICT_MODULE_RWX.
