This is a note to let you know that I have just added a patch titled ARM: 7778/1: smp_twd: twd_update_frequency need be run on all online to the linux-3.8.y-queue branch of the 3.8.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-3.8.y-queue This patch is scheduled to be released in version 3.8.13.5. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 9a7cd8342d52b7f3534cbd1494b78708365f2391 Mon Sep 17 00:00:00 2001 From: Jason Liu <r64343@freescale.com> Date: Mon, 1 Jul 2013 09:53:30 +0100 Subject: ARM: 7778/1: smp_twd: twd_update_frequency need be run on all online CPUs commit cbbe6f82b489e7ceba4ad7c833bd3a76cd0084cb upstream. When the local timer freq changed, the twd_update_frequency function should be run all the CPUs include itself, otherwise, the twd freq will not get updated and the local timer will not run correcttly. smp_call_function will run functions on all other CPUs, but not include himself, this is not correct,use on_each_cpu instead to fix this issue.
