Subject: [PATCH 1/6] arm64: unexport set_memory_x and set_memory_nx
Date: Tue, 13 Aug 2019 11:01:41 +0200 [thread overview]
Message-ID: <20190813090146.26377-2-hch@lst.de> (raw)
In-Reply-To: <20190813090146.26377-1-hch@lst.de>
No module currently messed with clearing or setting the execute
permission of kernel memory, and none really should.
