The current 2.6.x tree running on a Cobalt Qube throws an OOPS from
sys_swapon().
It looks like this is because line 1257 in r1.89 of mm/swapfile.c
(2.6.x) compiles to a BUG().
... swp_type(pte_to_swp_entry(swp_entry_to_pte(swp_entry(~0UL,0)))))
swp_entry(~0UL,0) --> f800_0000
swp_entry_to_pte(f800_0000)
__swp_entry(1f, 0000_0000) --> 0000_003e
pte_file(0000_003e) --> 0000_0010
BUG_ON(0000_0010)
