Hello,

In order to confirm a cache related problem , Is just setting
CONFIG_MIPS_UNCACHED is suficient..as so many places function
to operate on caches are  called directly while they should be
under "#ifdef CONFIG_MIPS_UNCACHED " if not technically then
atleast to make coding consistent.

secondly i am setting the uncached feature by,
change_cp0_config(CONF_CM_CMASK, CONF_CM_UNCACHED);

now, should the dump_tlb() show the page coherency attribute for 
each entries as "UNCACHED" in whole 4 gb address space..in my case 
for some entries the page coherency attribute is still showing 
"Cacheable, noncoherent, write-through, no write allocate".

Best Regards,
Atul
