Re: powerpc 476, Little-endian, pte fault

[Santosh Kumar]

i tried this but the fixup_user_fault is called as the path followed
is different. Also i see that the flags passed to handle_mm_fault is 0
i.e the fault is not on a write access. Please let me know if i have
to use this fix some where else too.

thanks
