Florian Fainelli 8a2b456665 MIPS: Fixed __debug_virt_addr_valid() 
It is permissible for kernel code to call virt_to_phys() against virtual
addresses that are in KSEG0 or KSEG1 and we need to be dealing with both
types. Rewrite the test condition to ensure that the kernel virtual
addresses are above PAGE_OFFSET which they must be, and below KSEG2
where the non-linear mapping starts.

For EVA, there is not much that we can do given the linear address range
that is offered, so just return any virtual address as being valid.

Finally, when HIGHMEM is not enabled, all virtual addresses are assumed
to be valid as well.
