Subject: [PATCH v3 extra 10/11] x86/mm: move {get, put}_page_from_l{2, 3, 4}e
Date: Sun, 30 Jul 2017 16:43:34 +0100 [thread overview]
Message-ID: <20170730154335.24313-11-wei.liu2@citrix.com> (raw)
In-Reply-To: <20170730154335.24313-1-wei.liu2@citrix.com>
They are only used by PV code.
Fix coding style issues while moving. Move declarations to PV specific
header file.
