Author: jkim Date: Thu Apr 28 22:23:39 2011 New Revision: 221188 URL: http://svn.freebsd.org/changeset/base/221188 Log: Define "Hypervisor Present" bit. This bit is used by several hypervisors to identify CPUs running under emulation. Currently QEMU-KVM, Xen-HVM, VMware, and MS Hyper-V are known to set this bit.
