From fa47ac59020e91082386f65a01f3e8cc6116ef95 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Wed, 21 Mar 2012 16:33:44 -0700 Subject: [PATCH] xtensa: don't reimplement force_sigsegv() Instead of open coding the sequence from force_sigsegv() just call it. This also fixes a bug because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]), whereas the intention of the code was to modify sighand->action[] directly. As the original code was working with a copy it had no effect on signal delivery.
