mempolicy: kill MPOL_F_LOCAL bit Now the only remaining case of actual 'local' policy faked by 'prefer' policy plus MPOL_F_LOCAL bit is: A valid 'prefer' policy with a valid 'preferred' node is 'rebind' to a nodemask which doesn't contains the 'preferred' node, then it will handle allocation with 'local' policy. Add a new 'MPOL_F_LOCAL_TEMP' bit for this case, and kill the MPOL_F_LOCAL bit, which could simplify the code much.
