Subject: [PATCH v3 5/6] tlb: arch: Remove empty __tlb_remove_tlb_entry() stubs
Date: Wed, 27 Jan 2021 23:53:46 +0000
Message-ID: <20210127235347.1402-6-will@kernel.org> (raw)
In-Reply-To: <20210127235347.1402-1-will@kernel.org>

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.
