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.
