but then sizes the containing data structure at run-time to make room for per-cpu cache data. Modify libmemstat to separately allocate a buffer to hold per-cpu cache data, sized based on the run-time mp_maxid variable when using libkvm to access UMA data. This avoids reading invalid cache data from beyond the end of the uma_zone data structure on the stack, which can result in invalid statistics and/or reads from invalid kernel addresses.
