From: David Hildenbrand Subject: [PATCH RFC 5/7] m68k/mm: use __ClearPageReserved() Date: Wed, 5 Dec 2018 13:28:49 +0100 Message-ID: <20181205122851.5891-6-david@redhat.com> References: <20181205122851.5891-1-david@redhat.com> Return-path: In-Reply-To: <20181205122851.5891-1-david@redhat.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-mm@kvack.org Cc: linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-m68k@lists.linux-m68k.org, linuxppc-dev@lists.ozlabs.org, linux-riscv@lists.infradead.org, linux-s390@vger.kernel.org, linux-mediatek@lists.infradead.org, David Hildenbrand , Geert Uytterhoeven , Andrew Morton , Michal Hocko , Matthew Wilcox List-Id: linux-mediatek@lists.infradead.org The PG_reserved flag is cleared from memory that is part of the kernel image (and therefore marked as PG_reserved). Avoid using PG_reserved directly.
