Subject[PATCH v7 0/7] make io{read|write}64 globally usable
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
