Description 
Some kstats were recently added to debug the ZFS L2ARC.  Two of them can become invalid on 32-bit systems:

# kstat -p zfs:::*hdr_size
zfs:0:arcstats:hdr_size 339302945920
zfs:0:arcstats:l2_hdr_size      0

hdr_size is too big, this is supposed to be bytes consumed by ARC headers.  No one knows about these kstats yet, but they should be fixed anyway.
