Subject: [PATCH 1/3] powerpc/fsl_booke: replace PAGE_OFFSET with KERNELBASE
Date: Fri, 5 Jul 2019 14:39:52 +0800 [thread overview]
Message-ID: <20190705063954.11674-2-yanaijie@huawei.com> (raw)
In-Reply-To: <20190705063954.11674-1-yanaijie@huawei.com>
We setup a mapping in PAGE_OFFSET and jump to KERNELBASE. This is not a
problem when PAGE_OFFSET = KERNELBASE. Replace PAGE_OFFSET with
KERNELBASE here to make it consistent.
