Author: marcel Date: Mon Nov 23 23:23:05 2009 New Revision: 199723 URL: http://svn.freebsd.org/changeset/base/199723
Log: Don't make MJUMPAGESIZE equal to PAGE_SIZE unconditionally. When PAGE_SIZE is 16K, MJUMPAGESIZE equals MJUM16BYTES and causes build breakages. For PAGE_SIZE < 2K, define MJUMPAGESIZE as MCLBYTES. For PAGE_SIZE > 8K, define MJUMPAGESIZE as 8K. Everywhere inbetween, define MJUMPAGESIZE as PAGE_SIZE. Thus MCLBYTES <= MJUMPAGESIZE <= 8KB.
