Subject: [PATCH 0/4] /proc/kmem fixes and hwpoison bits v3
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Hi,

Here are 2 bug fixes and also hwpoison checks for /dev/mem and /dev/kmem.
The bug fixes are intended for this merge window.

Changes since v2:
- remove the prototype change and make the bug fix simple
- add hwpoison checks for /dev/mem (this is in fact an old patch for me)

Changes since v1:
- change vread()/vwrite() prototype (proposed by Kame)
- include Kame's is_vmalloc_or_module_addr() check and use Hugh's -ENXIO.
- I decided not to use __GFP_ZERO, since the buf will be reused in the loop,
  so it would be better for vread to zero-fill it each time.
- removed the hwpoison checks for vmalloc pages. It seems that vread/vwrite
  could be simplified to handle one single page, and the hwpoison bits can be
  considered after that.

Thanks,
Fengguang
