[PATCH 2/4] csky/tlb: Remove tlb_flush() define

From: Peter Zijlstra
Date: Fri Jul 08 2022 - 03:20:13 EST


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.
