This cleanup was requested by Greg KH back in June of 2017. I've resent the series a couple times a cycle since then, updating and fixing as feedback was slowly recieved some patches were alread accepted by specific arches. In June 2018, Andrew picked the remainder of this up and it was in linux-next for a couple weeks. There were a couple problems that were identified and addressed back then and I'd really like to get the ball rolling again. A year and a half of sending this without much feedback is far too long. @Andrew, can you please pick this set up again so it can get into linux-next? Or let me know if there's something else I should be doing. Thanks, Logan --- Changes since v24: - Rebased onto v5.0-rc2 (No Changes) Changes since v23: - Rebased onto v4.20-rc4 (No Changes) Changes since v22: - Rebased onto v4.20-rc1 (No Changes) Changes since v21: - Rebased onto v4.19-rc6 (No Changes) Changes since v20: - Rebased onto v4.19-rc3 (No Changes) Changes since v19: - Rebased onto v4.19-rc1 (No Changes) Changes since v18: - Dropped the CAAM patch as it was subtly wrong and broke when people tested it in linux-next. Seeing the code is much trickier than it appears, we'll leave it to its maintainers to clean it up, should they chose. - Restored the ioread64/iowrite64 extern prototypes as despite appearing to be unusued, they are in fact used in a rare corner case by the caam driver on 64bit powerpc. This was reported by Guenter testing on linux-next. - Rebased onto v4.18-rc4 (No Changes) Changes since v17: - Rebased onto v4.18-rc1 (No Changes) Changes since v16: - Rebased onto v4.17-rc4 (No Changes) Changes since v15: - Rebased onto v4.17-rc1, dropping the powerpc patches which were picked up by Michael Changes since v14: - Rebased onto v4.16-rc7 - Replace the first two patches so that instead of correcting the endianness annotations we change to using writeX() and readX() with swabX() calls. This makes the big-endian functions more symmetric with the little-endian versions (with respect to barriers that are not included in the raw functions). As a side effect, it also fixes the kbuild warnings that the first two patches tried to address. Changes since v13: - Changed the subject of patch 0001 to correct a nit pointed out by Luc 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.
