New Revision: 354367
URL: https://svnweb.freebsd.org/changeset/base/354367
Log:
Switch cache zones from early counters to real implementation.
Early counter mock can be only used on BSP for amd64, when APs try to
update it that causes random memory corruption.
N.B. This is a temporary patch to plug the corruption for now, while
a proper solution for handling cache zones in zone_foreach() is being
developed.
