From 66ce75144d4b33e376f187df3dec495fe47d2ad0 Mon Sep 17 00:00:00 2001 From: Barry Song Date: Wed, 30 Jun 2021 18:56:31 -0700 Subject: kprobes: remove duplicated strong free_insn_page in x86 and s390 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.
