Using virt_addr_bits and get_virt_addr_bits is quite a mouthful. What
about using instead a pair of functions like these:
bool is_noncano
This patch exposes 5 level page table feature to the VM,
at the same time, the canonical virtual address checking is
extended to support both 48-bits and 57-bits address width,
it's the prerequisite to support 5 level paging guest.
