Whats your view on use of arch_ioremap_caller() hook ? This can allow
us to avoid the dual ioremap() issue discussed here if the hook
maintains the list of mapped ios.
I was even thinking of having such intelligence within the core
ioremap code but thought that might be too invasive.
Why do you even need it? There's no problem with ioremapping the same
space multiple times (you end up with multiple mappings but that
shouldn't be a problem, except for the additional space used.)
It just waste of iospace and Tony insisted to have just single ioremap()
hence all this discussion
