When should I use pte_offset_atomic?

[Timur Tabi <timur.tabi@xxxxxxxxxxx>]

Could someone please explain to me the various versions of pte_offset,
like pte_offset_map, pte_offset_kernel, and the new pte_offset_atomic? 
Red Hat 9.0, RH EL 3, Suse 9 Pro, and SLES 8 all claim to use a 2.4 
kernel, but each one has a different version of pte_offset that I need 
to use.
