Subject: [PATCH v2 0/3] make io{read|write}64 more globally usable

Hi,

This is my second attempt to cleanup the io{read|write}64 functions so
that I can use them in a new driver[1]. This time, per a suggestion from Arnd,
we simply add the io64 functions to the io-64-nonatomic headers and
cleanup the two obvious drivers. (Horia provided me with a corrected patch
for the crypto caam which I have included.)

I've droped the tilcdc patch as it does not appear to support
non-atomic accesses, so it's hack around iowrite64 will remain.

Thanks,

Logan
