Author: marius Date: Mon Jul 25 18:28:12 2011 New Revision: 224363 URL: http://svn.freebsd.org/changeset/base/224363 Log: MFC: r223378 On machines where we don't need to lock the kernel TSB into the dTLB and thus may basically use the entire 64-bit kernel address space reduce VM_KMEM_SIZE_SCALE to 1 allowing kernel to use more memory.
