[PATCH 4/4] KVM: selftests: Allocate ucall pool from MEM_REGION_DATA

Oliver Upton
2022-12-07T21:48:54Z

MEM_REGION_TEST_DATA is meant to hold data explicitly used by a
selftest, not implicit allocations due to the selftests infrastructure.
Allocate the ucall pool from MEM_REGION_DATA much like the rest of the
selftests library allocations.

Fixes: 426729b2cf2e ("KVM: selftests: Add ucall pool based implementation")
