Author: alc Date: Thu Mar 22 04:40:22 2012 New Revision: 233290 URL: http://svn.freebsd.org/changeset/base/233290 Log: Change pv_entry_count to a long. During the lifetime of FreeBSD 10.x, physical memory sizes at the high-end will likely reach a point that the number of pv entries could overflow an int.
