The kernel's default behaviour is to obstruct the allocation of high virtual address as it handles memory overcommit in a heuristic manner. Setting the parameter as OVERCOMMIT_ALWAYS, ensures kernel isn't susceptible to the availability of a platform's physical memory when denying a memory allocation request.

Which tests in particular require that?

This is applicable to the virtual address range selftest.

Subjects should start with "selftests/mm" instead of more generic "selftests:"

I'll make the necessary changes.
