Subject: [PATCH] selftests: kvm: fix overlapping addresses in
memslot_perf_test
vm_create allocates memory and maps it close to GPA. This memory
is separate from what is allocated in subsequent calls to
vm_userspace_mem_region_add, so it is incorrect to pass the
test memory size to vm_create_default. Just pass a small
fixed amount of memory which can be used later for page table,
otherwise GPAs are already allocated at MEM_GPA and the
test aborts.
