Currently userspace has no chance to find out which virtual address space we're in and resolve addresses. While that is a big problem for migration, it's also unpleasent when debugging, as gdb and the monitor don't work on virtual addresses. This patch exports enough of the MMU segment state to userspace to make debugging work and thus also includes the groundwork for migration.
