Subject: [PATCH v4 31/31] x86/mm: move {get, put}_page_from_l{2, 3, 4}e
Date: Thu, 17 Aug 2017 15:44:56 +0100 [thread overview]
Message-ID: <20170817144456.18989-32-wei.liu2@citrix.com> (raw)
In-Reply-To: <20170817144456.18989-1-wei.liu2@citrix.com>
They are only used by PV code.
Fix coding style issues while moving. Move declarations to PV specific
header file.
