Validate allocations against mappings Bug 120032857 is seeing what appears to be allocations with incorrect end addresses, leading to a much later crash when it tries to map a zero page outside the valid virtual address space. Detect allocations that extend outside the highest or lowest memory mapping and crash immediately instead. Test: memunreachable_test Bug: 120032857 Change-Id: I9be670a025143e7078360a6bf7a83219279614d9
