Re: [PATCH v2 1/3] selftests/mm: virtual_address_range: mmap() without PROT_WRITE

When mapping a larger chunk than physical memory is available with PROT_WRITE and overcommit is disabled, the mapping will fail. This will prevent the test from running on systems with less then ~1GiB of memory and triggering an inscrutinable test failure. As the mappings are never written to anyways, the flag can be removed.
