In order to support 52-bit kernel addresses detectable at boot time, one needs to know the actual VA_BITS detected. A new variable vabits_actual is introduced in this commit and employed for the KVM hypervisor layout, KASAN, fault handling and phys-to/from-virt translation where there would normally be compile time constants. In order to maintain performance in phys_to_virt, another variable physvirt_offset is introduced.
