Subject: [PATCH 4.9 37/91] iommu/io-pgtable-arm-v7s: Only kmemleak_ignore L2 tables
Date: Thu,  4 Apr 2019 10:47:21 +0200	[thread overview]
Message-ID: <20190404084537.610022556@linuxfoundation.org> (raw)
In-Reply-To: <20190404084535.450029272@linuxfoundation.org>

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 032ebd8548c9d05e8d2bdc7a7ec2fe29454b0ad0 ]

L1 tables are allocated with __get_dma_pages, and therefore already
ignored by kmemleak.

Without this, the kernel would print this error message on boot,
when the first L1 table is allocated:

[    2.810533] kmemleak: Trying to color unknown object at 0xffffffd652388000 as Black
