Thanks, Logan --- 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.
