Since alpha does not include asm-generic/io.h it would mean
alpha folks have to always carefully monitor asm-generic patches
and before they get merged make sure their own arch implementation
solution gets added. By using asm-generic/io.h alpha gets sensible
defaults, in this case ioremap_uc() would be one example, where
by default it would return NULL, so not implemented. When alpha
folks get a chance then they can add the appropriate
implementation.

Doesn't work. Gives me lots of duplicate symbols.

The easy solution *for now* is to just do:
#define ioremap_uc ioremap_nocache
*But* that would have to be done for any other asm-generic/io.h collateral
evolution, this on the other hand, would get it right for alpha from the
get-go -- so I ask -- can this please be tested and if it is OK then consider
it be merged?
If we can't add asm-generic/io.h then the above define replacement would
be the way to go.
