Author: kaktus Date: Mon Jan 6 10:52:13 2020 New Revision: 356413 URL: https://svnweb.freebsd.org/changeset/base/356413 Log: sysctl: mark more nodes as MPSAFE vm.kvm_size and vm.kvm_free are read only and marked as MPSAFE on i386 already. Mark them as that on amd64 and arm64 too to avoid locking Giant.
