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.
