The previous patch removed the tlb_flush_end() implementation which used tlb_flush_range(). This means: - csky did double invalidates, a range invalidate per vma and a full invalidate at the end - csky actually has range invalidates and as such the generic tlb_flush implementation is more efficient for it.
