From 3e66701cbda2e04bb62e0afe2f3d86c9d3d76b24 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Sun, 13 Jul 2014 17:45:11 +0200 Subject: [PATCH] xtensa: Remove signal translation and exec_domain As execution domain support is gone we can remove signal translation from the signal code and remove exec_domain from thread_info.
