free_insn_page() in x86 and s390 is same with the common weak function in kernel/kprobes.c. Plus, the comment "Recover page to RW mode before releasing it" in x86 seems insensible to be there since resetting mapping is done by common code in vfree() of module_memfree(). So drop these two duplicated strong functions and related comment, then mark the common one in kernel/kprobes.c strong.
