From 03b3e82a78c32c7e4542c33fcd863028cddd9331 Mon Sep 17 00:00:00 2001 From: Alexander Gordeev Date: Tue, 7 Jan 2025 08:40:06 +0100 Subject: [PATCH] s390/tlb: Add missing TLB range adjustment While converting to generic mmu_gather with commit 9de7d833e370 ("s390/tlb: Convert to generic mmu_gather") __tlb_adjust_range() is called from pte|pmd|p4d_free_tlb(), but not for pud_free_tlb(). __tlb_adjust_range() adjusts the span of TLB range to be flushed, but s390 does not make use of it. Thus, this change is only for consistency.
