Author: neel Date: Sat Jul 6 06:24:19 2013 New Revision: 252865 URL: http://svnweb.freebsd.org/changeset/base/252865 Log: Since 'pm_pml4' is always a direct mapped address use DMAP_TO_PHYS() to get the physical address instead of getting it from recursive page table index. This allows 'pmap_release()' to work with pmaps that may not have the recursive page table index populated (e.g. PT_EPT).
