Author: marcel Date: Mon Dec 7 06:41:27 2009 New Revision: 200207 URL: http://svn.freebsd.org/changeset/base/200207 Log: Define struct pcpu_md as the only MD field of struct pcpu (pc_acpi_id excluded, as it's used by MI code) and mode the sysctl variables from pcpu_stats to pcpu_md. Adjust all references accordingly. While nearby, change the PCPU sysctl tree so that they match the CPU device sysctl tree -- they are now children of a static node called "machdep.cpu" and are named only with their cpu ID.
