From f18046f7a50accf76dab9c6ab274a7e38143a0dc Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Thu, 4 Jan 2018 16:17:56 -0800 Subject: [PATCH] kernel/exit.c: export abort() to modules commit dc8635b78cd8669c37e230058d18c33af7451ab1 upstream. gcc -fisolate-erroneous-paths-dereference can generate calls to abort() from modular code too.
