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

From: Will Deacon
Date: Wed Jan 27 2021 - 18:55:41 EST


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.
