Subject: [PATCH 4.14 13/53] drm: Use kvzalloc for allocating blob property memory
Date: Tue, 10 Jul 2018 20:24:49 +0200 [thread overview]
Message-ID: <20180710182459.676732051@linuxfoundation.org> (raw)
In-Reply-To: <20180710182458.736721865@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michel Dänzer <michel.daenzer@amd.com>
commit 718b5406cd76f1aa6434311241b7febf0e8571ff upstream.
The property size may be controlled by userspace, can be large (I've
seen failure with order 4, i.e. 16 pages / 64 KB) and doesn't need to be
physically contiguous.
