Subject: [PATCH v5 0/6] make io{read|write}64 globally usable

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 (5):
  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
