    Add node/node_type attribute "no_clflush". · fdfce71d
    Mike Hibler authored
    This is for FreeBSD to turn off use of the CLFLUSH instruction via the
    hw.clflush_disable loader var. We have encountered some opteron machines
    on which this causes problems.
    
    The attribute can be set for the node_type (via the web page for editing
    node types) or the node (via brute-force SQL hackary) to override whatever
    FreeBSD would do by default. This attribute is passed via tmcd to the
    diskloader MFS which will fixup the loader.conf file post-frisbee.
