[PATCH 15/15] KVM: selftests: Get rid of gorilla math in memslots modification test

From: Sean Christopherson
Date: Wed Feb 10 2021 - 18:13:37 EST


Use the recently added perf_test_args.nr_bytes to define the location of
the dummy memslot created/removed by the memslot modification test.
Presumably, the goal of the existing code is simply to ensure the GPA of
the dummy memslot doesn't overlap with perf_test's memslot.
