* enables world-switch using ARM virtualization extensions * split TrustZone and virtualization extensions hardly from platforms, where it is not used * extend 'Vm_session' interface to enable configuration of guest-physical memory * introduce VM destruction syscall * add virtual machine monitor for hw_arndale that emulates a simplified version of ARM's Versatile Express Cortex A15 board for a Linux guest OS Fixes #1405
