From b807a1087ed864f6c37ccbf6ea416387f00a8b3c Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 29 Sep 2021 09:05:31 -0400 Subject: linux-user/arm: Drop "_v2" from symbols in signal.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since we no longer support "v1", there's no need to distinguish "v2".
