Subject: [PATCH 0/4] Fix check address limit on user-mode
Date: Thu,  7 Sep 2017 08:30:43 -0700	[thread overview]
Message-ID: <1504798247-48833-1-git-send-email-keescook@chromium.org> (raw)

Fixes from Thomas Garnier: the new address limit check was causing
hangs on ARM. This solves the problem and takes proactive steps on
ARM64. Additionally removes the unconditional BUG_ON() on check failures.
