Author: ivoras

New Revision: 184570
URL: http://svn.freebsd.org/changeset/base/184570

Log:
  Increase the initial sbuf size for CPU topology dump to something more
  usable for newer CPUs. The new value allows 2 x quad core configuration
  dumps to fit within the initial buffer without reallocations.
