From b0aa5e4b087b686575f1b31ce54048b4d059b7b8 Mon Sep 17 00:00:00 2001 From: "Mike Rapoport (Microsoft)" Date: Fri, 17 Apr 2026 13:32:07 +0300 Subject: [PATCH] sh: Fix fallout from ZERO_PAGE consolidation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidation of empty_zero_page declarations broke boot on sh. sh stores its initial boot parameters in a page reserved in arch/sh/kernel/head_32.S. Before commit 6215d9f4470f ("arch, mm: consolidate empty_zero_page") this page was referenced in C code as an array and after that commit it is referenced as a pointer. This causes wrong code generation and boot hang. Declare boot_params_page as an array to fix the issue.
