This is v9 of my cleanup series to push a number of instances of people defining their own io{read|write}64 functions when 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. 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.
