[PATCH] selftests/kvm: fix compilation on non-x86_64 platforms

From: Paolo Bonzini
Date: Tue Nov 21 2023 - 11:59:26 EST


MEM_REGION_SLOT and MEM_REGION_GPA are not really needed in
test_invalid_memory_region_flags; the VM never runs and there are no
other slots, so it is okay to use slot 0 and place it at address
zero. This fixes compilation on architectures that do not
define them.

Fixes: 5d74316466f4 ("KVM: selftests: Add a memory region subtest to validate invalid flags", 2023-11-14)
