That's not true. E.g. I/O memory is never mapped by mem_init().
Why, then, does the ioremap() of ST-RAM fail? Because the physical

is lower than the lowest currently mapped physical address?
I don't know. How does it fail?
Example:
Unable to handle kernel access at virtual address 5f435059
Oops: 00000000

This may be too early in the boot process to call ioremap().
