Subject: [PATCH v2 11/15] loongarch: drop definition of PUD_ORDER
Date: Tue, 5 Jul 2022 18:47:04 +0300 [thread overview]
Message-ID: <20220705154708.181258-12-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 PUD.
Since its always hardwired to 0, simply drop it.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
