In theory Linux/Alpha could eventually give the user 62 bits of VM
address space. The current CPU implementations limit us to 43 bits.
> Do file offsets have 64 bit addressability?
Yes, off_t is 64 bits. None of the underlying filesystems currently
support files that big, but the VFS layer does not disallow it.

Of course.
