This is a note to let you know that I have just added a patch titled genirq: Provide irq_force_affinity fallback for non-SMP to the linux-3.13.y-queue branch of the 3.13.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-3.13.y-queue This patch is scheduled to be released in version 3.13.11.4. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 4302e1f09f3444b8b08caa45b43f8ae422f70bd4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd@arndb.de> Date: Wed, 23 Apr 2014 14:49:17 +0200 Subject: genirq: Provide irq_force_affinity fallback for non-SMP commit 4c88d7f9b0d5fb0588c3386be62115cc2eaa8f9f upstream. Patch 01f8fa4f01d "genirq: Allow forcing cpu affinity of interrupts" added an irq_force_affinity() function, and 30ccf03b4a6 "clocksource: Exynos_mct: Use irq_force_affinity() in cpu bringup" subsequently uses it. However, the driver can be used with CONFIG_SMP disabled, but the function declaration is only available for CONFIG_SMP, leading to this build error: drivers/clocksource/exynos_mct.c:431:3: error: implicit declaration of function 'irq_force_affinity' [-Werror=implicit-function-declaration] irq_force_affinity(mct_irqs[MCT_L0_IRQ + cpu], cpumask_of(cpu)); This patch introduces a dummy helper function for the non-SMP case that always returns success, to get rid of the build error. Since the patches causing the problem are marked for stable backports, this one should be as well.
