Subject: [PATCH v2 5/7] ARM: mm: Print physical address of page table base in show_pte()
Date: Wed, 2 Jun 2021 15:02:44 +0800	[thread overview]
Message-ID: <20210602070246.83990-6-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20210602070246.83990-1-wangkefeng.wang@huawei.com>

Now the show_pts() will dump the virtual (hashed) address of page
table base, it is useless, let's print the page table base pointer
as a physical address for debug.
