From 3050a35fba296196cb00e87f4a96aa7d9ed17a7b Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Sun, 13 Jul 2014 17:43:51 +0200 Subject: [PATCH] x86: 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.
