Author: alc Date: Tue Feb 26 08:17:34 2013 New Revision: 247314 URL: http://svnweb.freebsd.org/changeset/base/247314 Log: Be more conservative in auto-sizing and capping the kmem submap. In fact, use the same values here that we use on 32-bit x86 and MIPS. Some machines were reported to have problems with the more aggressive values.
