[PATCH] ia64: define ioremap_uc()

[PATCH] ia64: define ioremap_uc()

[Luis R. Rodriguez]

All architectures now need ioremap_uc(), ia64 seems defines
this already through its ioremap_nocache() and it already
ensures it *only* uses UC.

Note, this is actually needed since v4.3 to complete an allyesconfig
compile on ia64, there were others archs that needed this, and this
one just seems to have fallen through the cracks.

So a cc:stable was needed.  I've added that to my copy of the patch. 
Tony ack?
