Author: fjoe Date: Sun Nov 28 19:26:20 2010 New Revision: 216016 URL: http://svn.freebsd.org/changeset/base/216016 Log: Define VM_KMEM_SIZE_MAX on sparc64. Otherwise kernel built with DEBUG_MEMGUARD panics early in kmeminit() with the message "kmem_suballoc: bad status return of 1" because of zero "size" argument passed to kmem_suballoc() due to "vm_kmem_size_max" being zero. The problem also exists on ia64.
