  Modified:    sys/miscfs/kernfs  kernfs_vfsops.c kernfs_vnops.c
               sys/miscfs/procfs  procfs.h procfs_vfsops.c procfs_vnops.c
  Log:
  Fixed panic that resulted from mmaping files in kernfs and procfs. A
  regular user could panic the machine with a simple "tail /proc/curproc/mem"
  command. The problem was twofold: both kernfs and procfs didn't fill in
  the mnt_stat statfs struct (which would later lead to an integer divide
  fault in the vnode pager), and kernfs bogusly paniced if a bmap was
  attempted.
