It may just work but cannot be enabled because I cannot test kmemleak on
such hardware. In general you need to make sure that the _sdata/_edata
and __bss_start/__bss_stop symbols are defined. If there are other ways
of allocating memory than the standard API, it would need additional
hooks. Some false-positives specific to MIPS may need to be annotated
(usually with kmemleak_not_leak).

(btw, you could also merge the kmemleak.git tree on as it
has improvements on the rate of false positives; the patches will be
pushed in 2.6.33-rc1)
