New Revision: 235776
URL: http://svn.freebsd.org/changeset/base/235776
Log:
Fix booting on ARM.
In PHYS_TO_VM_PAGE() when VM_PHYSSEG_DENSE is set the check if we are past
the end of vm_page_array was incorrect causing it to return NULL. This
value is then used in vm_phys_add_page causing a data abort.
