Subject: [PATCH 07/19] KVM: selftests: Lower the min virtual address for misc
 page allocations

Reduce the minimum virtual address of page allocations from 0x10000 to
KVM_UTIL_MIN_VADDR (0x2000).  Both values appear to be completely
arbitrary, and reducing the min to KVM_UTIL_MIN_VADDR will allow for
additional consolidation of code.
