From c7bcbc8ab9cb20536b8f50c62a48cebda965fdba Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 17 Jul 2020 13:10:07 +0200 Subject: sh/tlb: Fix PGTABLE_LEVELS > 2 Geert reported that his SH7722-based Migo-R board failed to boot after commit: c5b27a889da9 ("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().
