>Let's not get that confused with "immediate x86-64 support" as most people are prone to doing.<

This is not entirely true. I remember when IBM mainframes could support a 48MB physical address space, but only run 16MB partitions. With Hammer a similar situation will exist. Linux will be capable of running in x86-64 mode and addressing up to 48-bits of address space, but the actual applications will be x86-32, capable of addressing only 32-bits (36-bits if you want to get technical) of address space. As a result, Hammer will be capable of for example, running multiple copies of a database query application, with each utilizing less than 32-bits of address space.
