[PATCH v3 5/6] tlb: arch: Remove empty __tlb_remove_tlb_entry() stubs

From: Will Deacon <will@kernel.org>
Date: 2021-01-27 23:55:45
Also in: lkml
Subsystem: mmu gather and tlb invalidation, sparc + ultrasparc (sparc/sparc64), the rest, x86 architecture (32-bit and 64-bit) · Maintainers: Will Deacon, "Aneesh Kumar K.V", Andrew Morton, Nick Piggin, Peter Zijlstra, "David S. Miller", Andreas Larsson, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen

If __tlb_remove_tlb_entry() is not defined by the architecture then
we provide an empty definition in asm-generic/tlb.h.

Remove the redundant empty definitions for sparc64 and x86.
