Subject: [PATCH v17 7/7] ntb: ntb_hw_switchtec: Cleanup 64bit IO defines to use the common header
Date: Mon,  7 May 2018 14:36:05 -0600	[thread overview]
Message-ID: <20180507203605.15865-8-logang@deltatee.com> (raw)
In-Reply-To: <20180507203605.15865-1-logang@deltatee.com>

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.
