From mboxrd@z Thu Jan 1 00:00:00 1970 From: Logan Gunthorpe Subject: [PATCH v7 0/7] make io{read|write}64 globally usable Date: Tue, 22 Aug 2017 11:02:21 -0600 Message-ID: <20170822170228.17196-1-logang@deltatee.com> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, linux-ntb@googlegroups.com, linux-crypto@vger.kernel.org Cc: Arnd Bergmann , Greg Kroah-Hartman , Andy Shevchenko , =?UTF-8?q?Horia=20Geant=C4=83?= , Stephen Bates , Logan Gunthorpe List-Id: linux-arch.vger.kernel.org This is just a resend seeing I've gotten no feedback in a couple weeks. Changes since v6: ** none ** Changes since v5: - Added a fix to the tilcdc driver to ensure it doesn't use the non-atomic operation. (This includes adding io{read|write}64[be]_is_nonatomic defines). Changes since v4: - Add functions so the powerpc implementation of iomap.c compiles. (As noticed by Horia) Changes since v3: - I noticed powerpc didn't use the appropriate functions seeing readq/writeq were not defined when iomap.h was included. Thus I've included a patch to adjust this - Fixed some mistakes with a couple of the defines in io-64-nonatomic* headers - Fixed a typo noticed by Horia.
