*	powerpc/mm/radix: Add tlbflush routines	Aneesh Kumar K.V	2016-05-01	1	-0/+33
	Core kernel doesn't track the page size of the VA range that we are invalidating. Hence we end up flushing TLB for the entire mm here. Later patches will improve this. We also don't flush page walk cache separetly instead use RIC=2 when flushing TLB, because we do a MMU gather flush after freeing page table. MMU_NO_CONTEXT is updated for hash.
