Author: peter Date: Sat Dec 6 19:54:50 2008 New Revision: 185716 URL: http://svn.freebsd.org/changeset/base/185716 Log: MFC: 185548 and followups. Add new KERN_PROC_* handlers with 32/64 bit stable interfaces. Pack records from sysctl to reduce copyout size. Add helper to unpack and provide a more stable interface.
