New Revision: 215280
URL: http://svn.freebsd.org/changeset/base/215280
Log:
Workaround build for PAE case for now - revert the PHYS
case to previous panic behavior.
I have a real fix that changes the sg dma tag allocation
to be limited to the under 4GB address space but would
prefer to have review before committing.
