Subject: [PATCH v2 13/15] parisc: Rename PGD_ORDER to PGD_TABLE_ORDER
Date: Tue, 5 Jul 2022 18:47:06 +0300 [thread overview]
Message-ID: <20220705154708.181258-14-rppt@kernel.org> (raw)
In-Reply-To: <20220705154708.181258-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
This is the order of the page table allocation, not the order of a PGD.
