Subject: [PATCH v13 10/10] ntb: ntb_hw_switchtec: Cleanup 64bit IO defines to use the common header
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Clean up the ifdefs which conditionally defined the io{read|write}64
functions in favour of the new common io-64-nonatomic-lo-hi header.

Per a nit from Andy Shevchenko, the include list is also made
alphabetical.
