This is a note to let you know that I have just added a patch titled ioatdma: Fix bug in selftest after removal of DMA_MEMSET. to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 8a3bbd0e0ea90ecef33022879d74786a28eed894 Mon Sep 17 00:00:00 2001 From: Dave Jiang <dave.jiang@intel.com> Date: Wed, 6 Nov 2013 08:50:09 -0700 Subject: ioatdma: Fix bug in selftest after removal of DMA_MEMSET. commit ac7d631f7d9f9e4e6116c4a72b6308067d0a2226 upstream. Commit 48a9db4 (3.11) removed the memset op in the xor selftest for ioatdma. The issue is that with the removal of that op, it never replaced the memset with a CPU memset. The memory being operated on is expected to be zeroes but was not. This is causing the xor selftest to fail.
