  SVN rev 216406 on 2010-12-13 12:34:35Z by rwatson
  
  Merge r216365 from head to stable/8:
  
    Derive the XENHVM kernel from GENERIC, adding only the options required
    to support PV drivers (such as xenpci), and non-adptive locking (along
    with a comment about why).
  
    This change eliminates the synchronisation problem between GENERIC and
    XENHVM, which had become severely rotted in HEAD, and in 8-STABLE
    included non-production kernel debugging features such as WITNESS.
  
    However, it comes at the cost of enabling devices and options that may
    not be present under Xen (such as random ethernet cards).  For now, opt
    for a simpler kernel configuration file rather than using nooptions/
    nodevice to enumerate and eliminate them.  This leads to a somewhat
    larger XENHVM kernel.
  
    This is an MFC candidate for 8-STABLE before 8.2, in order to provide
    a production-worthy XENHVM kernel configuration for amd64.
