[ Upstream commit c7bcbc8ab9cb20536b8f50c62a48cebda965fdba ] Geert reported that his SH7722-based Migo-R board failed to boot after commit:c5b27a889d("sh/tlb: Convert SH to generic mmu_gather") That commit fell victim to copying the wrong pattern -- __pmd_free_tlb() used to be implemented with pmd_free(). Fixes:c5b27a889d("sh/tlb: Convert SH to generic mmu_gather") Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rich Felker <dalias@libc.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
