From 953dbbed9ee310100bc841cdea8f992d192531c6 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Tue, 21 May 2013 12:16:56 +0100 Subject: arm64: Do not report user faults for handled signals Currently user faults (page, undefined instruction) are always reported even though the user may have a signal handler for them. This patch adds unhandled_signal() check together with printk_ratelimit() for these cases.
