From c2d3f25dda016d9697c5416810d4528770f0a281 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 9 Oct 2013 14:08:09 +0200 Subject: [PATCH] uprobes: Remove the wrong __weak attribute linux/uprobes.h declares arch_uprobe_skip_sstep() as a weak function. But as there is no definition of generic version so when trying to build uprobes for an architecture that doesn't yet have a arch_uprobe_skip_sstep() implementation, the vmlinux will try to call arch_uprobe_skip_sstep() somehwere in Stupidhistan leading to a system crash. We rather want a proper link error so remove arch_uprobe_skip_sstep().
