Subject: [PATCH 2/4] csky/tlb: Remove tlb_flush() define
References: <20220708071802.751003711@infradead.org>
MIME-Version: 1.0

Precedence: bulk

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.
