[PATCH v13 00/10] Add io{read|write}64 to io-64-atomic headers
This is v13 of my cleanup series to push a number of instances of people
defining their own io{read|write}64 functions into common headers seing
they don't exist in non-64bit systems. This series adds inline functions to the
io-64-nonatomic headers and then cleans up the drivers that defined their
own copies.
This cleanup was originally requested by Greg after he reviewed my
Switchtec NTB code. And I hope someone can pick it up or at least give
feedback on it soon as it's been around relatively unchanged for a few
cycles now and I'm getting a bit tired of resubmitting it with little to
no interest.
Thanks,
Logan

Changes since v12:
- Rebased onto v4.16-rc6
- Split patch 0001 into two and reworked the commit log as requested
by Luc Van Oostenryck
Changes since v11:
- Rebased onto v4.16-rc5
- Added a patch (0001) to fix some old and new sparse warnings
that the kbuild robot warned about this cycle. The latest version
of sparse was required to reproduce these.
- Added a patch (0002) to add io{read|write}64 to parisc which the kbuild
robot also found errors for this cycle
Changes since v10:
- Rebased onto v4.16-rc4, this droped the drm/tilcdc patch which was
picked up by that tree and is already in 4.16.
Changes since v9:
- Rebased onto v4.15-rc6
- Fixed a couple of issues in the new version of the CAAM patch as
pointed out by Horia
Changes since v8:
- Rebased onto v4.15-rc2, as a result rewrote patch 7 seeing someone did
some similar cleanup in that area.
- Added a patch to clean up the Switchtec NTB driver which landed in
v4.15-rc1
Changes since v7:
- Fix minor nits from Andy Shevchenko
- Rebased onto v4.14-rc1
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.
(earlier versions were drastically different)
