Chaitanya S Prakash d6c2789778 selftests/mm: set overcommit_policy as OVERCOMMIT_ALWAYS
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.
