qemu_vmalloc: align properly for transparent hugepages and KVM
To make good use of transparent hugepages, KVM requires that guest-physical
and host-virtual addresses share the low 21 bits (as opposed to just the low
12 bits normally required).
Adjust qemu_vmalloc() to honor that requirement. Ignore it for small regions
to avoid fragmentation.
