[PATCH v18 7/7] ntb: ntb_hw_switchtec: Cleanup 64bit IO defines to use the common header
From: Logan Gunthorpe <logang@deltatee.com>
Date: 2018-06-22 19:48:03
Also in:
linux-crypto, lkml
Subsystem:
ntb driver core, pci driver for microsemi switchtec, the rest · Maintainers:
Jon Mason, Dave Jiang, Allen Hubbe, Kurt Schwemmer, Logan Gunthorpe, Linus Torvalds
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.
