[Don Lewis]

Author: truckman
Date: Mon Jan 30 07:23:53 2012
New Revision: 230764
URL: http://svn.freebsd.org/changeset/base/230764

Log:
  MFC r230064:
  
  Allow an MBR primary or extended Linux swap partition to be specified
  as the system dump device.  This was already allowed for GPT.  The Linux
  swap metadata at the beginning of the partition should not be disturbed
  because the crash dump is written at the end.
