From 269583559cdd8ab1203210893590ed4cc6af8171 Mon Sep 17 00:00:00 2001 From: Dave Martin Date: Fri, 30 Jun 2017 18:56:09 +0100 Subject: [PATCH] ARM: 8686/1: iwmmxt: Add missing __user annotations to sigframe accessors preserve_iwmmxt_context() and restore_iwmmxt_context() lack __user accessors on their arguments pointing to the user signal frame. There does not be appear to be a bug here, but this omission is inconsistent with the crunch and vfp sigframe access functions. This patch adds the annotations, for consistency.
