From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit e16343c47e4276f5ebc77ca16feb5e50ca1918f9 upstream. The warning was introduced in 2009 (commit 4bf1fa5a34aa ([ARM] 5613/1: implement CALLER_ADDRESSx)). The only "problem" here is that CALLER_ADDRESSx for x > 1 returns NULL which doesn't do much harm. The drawback of implementing a fix (i.e. use unwind tables to implement CALLER_ADDRESSx) is that much of the unwinder code would need to be marked as not traceable.
