Author: cherry Date: Wed Jun 25 08:45:35 2014 New Revision: 267855 URL: http://svnweb.freebsd.org/changeset/base/267855 Log: On XEN PV, in order to include reclaimed startup/bootstrap pages, we need to set low_water to 0, unlike on native. XEN on amd64 uses the direct map, so include all mapped kernel pages in the crash dump, just like native.
