Re: [Xen-devel] [PATCH v6 1/9] efi: Use early_mem*() instead of early_io*()

The *_unmap() functions are no-op on ia64 - because we have mappings for 
everything all the time
- the *_map() functions just need to compute the proper address to use to get 
the right attributes
(so we don't mix and match cacheable and uncachable access to the same 
address). But there is
nothing to tear down afterwards.

I do tend to agree with Daniel that is seems odd to setup the mapping with one 
class of function
and then tear it down with another.
