Not really fair. It crashed lately because until now I was the only
one to use it. And unfortunately I failed to give back this change to
Ralf's tree.
BUT, note that the root cause of this bug is that we did _plain_
address translation instead of using dedicated macro.
So I would say that this patch helps to fix these buggy places.
What can PHYS_OFFSET achieve here - besides obfuscating ?
Are there future uses for it, that justify the contortions ?
How do you deal with fancy cases such as physical memory starting at
0x20000000 for example ?
