Author: neel Date: Tue Sep 16 04:01:55 2014 New Revision: 271662 URL: http://svnweb.freebsd.org/changeset/base/271662 Log: Minor cleanup. Get rid of unused 'svm_feature' from the softc. Get rid of the redundant 'vcpu_cnt' checks in svm.c. There is a similar check in vmm.c against 'vm->active_cpus' before the AMD-specific code is called.
