| |
This is just a resend seeing I've gotten no feedback in a couple weeks.
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)
Horia Geantă (1): crypto: caam: cleanup CONFIG_64BIT ifdefs when using io{read|write}64
Logan Gunthorpe (6): drm/tilcdc: ensure nonatomic iowrite64 is not used powerpc: io.h: move iomap.h include so that it can use readq/writeq defs powerpc: iomap.c: introduce io{read|write}64_{lo_hi|hi_lo} iomap: introduce io{read|write}64_{lo_hi|hi_lo} io-64-nonatomic: add io{read|write}64[be]{_lo_hi|_hi_lo} macros ntb: ntb_hw_intel: use io-64-nonatomic instead of in-driver hacks
