The combination of the pool-based ucall implementation + page_fault_test
resulted in some 'fun' bugs, not the least of which is that our handling
of the VA space on arm64 is completely wrong.

Small series to fix up the issues on kvm/queue. Patches 1-2 can probably
be squashed into Paolo's merge resolution, if desired.

Mark Brown (1):
  KVM: selftests: Fix build due to ucall_uninit() removal

Oliver Upton (3):
  KVM: selftests: Setup ucall after loading program into guest memory
  KVM: arm64: selftests: Align VA space allocator with TTBR0
  KVM: selftests: Allocate ucall pool from MEM_REGION_DATA
