From 221e00d1fce976d8a04ff591a0150caf84e176f8 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Sat, 23 Jun 2018 12:36:22 +0200 Subject: crypto: x86 - Add missing RETs Add explicit RETs to the tail calls of AEGIS and MORUS crypto algorithms otherwise they run into INT3 padding due to ("x86/asm: Pad assembly functions with INT3 instructions") leading to spurious debug exceptions. Mike Galbraith took care of all the remaining callsites.
