Subject: [PATCH 14/14] xtensa: drop definition of PGD_ORDER
Date: Sun, 3 Jul 2022 17:12:03 +0300 [thread overview]
Message-ID: <20220703141203.147893-15-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.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
