Author: andrew Date: Tue May 22 14:26:58 2018 New Revision: 334045 URL: https://svnweb.freebsd.org/changeset/base/334045 Log: Pass the array length into regions_to_avail. On arm64 we will need to get the phys_avail array from before the kernel is excluded to create teh DMAP region. In preperation for this pass in the array length into regions_to_avail.
