This is a note to let you know that I have just added a patch titled cxl: Set endianess of kernel contexts to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt2. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From e1350d5b6b829c6a3d0f0f09a6f884b9be6ca4d2 Mon Sep 17 00:00:00 2001 From: Frederic Barrat <fbarrat@linux.vnet.ibm.com> Date: Mon, 7 Dec 2015 14:34:40 +0100 Subject: cxl: Set endianess of kernel contexts commit e606e035cc7293a3824527d97359711fdda00663 upstream. A process element (defined in CAIA) keeps track of the endianess of contexts through the Little Endian (LE) bit of the State Register. It is currently set for user contexts, but was somehow forgotten for kernel contexts, so this patch fixes it. It could lead to erratic behavior from an AFU when the context is attached through the kernel API.
