Author: marius Date: Mon Jul 25 14:33:37 2011 New Revision: 224310 URL: http://svn.freebsd.org/changeset/base/224310 Log: MFC: r216016 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.
