New Revision: 216306
URL: http://svn.freebsd.org/changeset/base/216306
Log:
MFi386 r1.94: If XEN, make pmap_kextract = pmap_kextract_ma. This is a
no-op currently, since FreeBSD/amd64 doesn't have (paravirtualized) Xen
support, but if/when that support is ever added we'll want this, and
until then it's harmless.
