Max Wash 8803c23f08 vm: improve memory usage under sparse with a high reserved memory ratio ...

previously, sparse would attempt to create a smaller number of larger sectors on systems with lots of reserved memory, often causing an out-of-memory condition. the reserved memory ratio calculation now compares reserved memory to free memory, rather than to the address of the last byte in physical memory. this improved heuristic means sparse is now better at choosing an appropriate sector size, allowing sparse to operate on systems with high amounts of reserved memory.
