This can be trivially accomplished by providing spare fields and versioning the struct, as implemented in the patch below. The upshots are one less memory indirection on each alloc and disappearance of mt_zone.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

That fixes libmemstat with arbitrary large MAXCPU values and therefore eliminates MEMSTAT_ERROR_TOOMANYCPUS error type.

This is provided via a new query function, memstat_kvm_malloc(), which is also automatically invoked by memstat_kvm_all(). A kvm handle must be passed in. This will allow malloc(9)-specific code to be removed from vmstat(8).
