Subject: [PATCH v5 11/23] x86/mm: move compat descriptor table manipulation code
Date: Thu, 14 Sep 2017 13:58:40 +0100 [thread overview]
Message-ID: <20170914125852.22129-12-wei.liu2@citrix.com> (raw)
In-Reply-To: <20170914125852.22129-1-wei.liu2@citrix.com>
Move them alongside the non-compat variants.
Change u{32,64} to uint{32,64}_t while moving.
