Subject: [PATCH 02/14] csky: drop definition of PGD_ORDER
Date: Sun,  3 Jul 2022 17:11:51 +0300	[thread overview]
Message-ID: <20220703141203.147893-3-rppt@kernel.org> (raw)
In-Reply-To: <20220703141203.147893-1-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.
Since its always hardwired to 0, simply drop it.
