This is a note to let you know that I have just added a patch titled MIPS: ftrace: Fix a microMIPS build problem to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt1. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 7763c7e6513ebb419c32fc95dce08918c530d2a0 Mon Sep 17 00:00:00 2001 From: Markos Chandras <markos.chandras@imgtec.com> Date: Mon, 20 Oct 2014 09:39:31 +0100 Subject: MIPS: ftrace: Fix a microMIPS build problem commit aedd153f5bb5b1f1d6d9142014f521ae2ec294cc upstream. Code before the .fixup section needs to have the .insn directive. This has no side effects on MIPS32/64 but it affects the way microMIPS loads the address for the return label. Fixes the following build problem: mips-linux-gnu-ld: arch/mips/built-in.o: .fixup+0x4a0: Unsupported jump between ISA modes; consider recompiling with interlinking enabled. mips-linux-gnu-ld: final link failed: Bad value Makefile:819: recipe for target 'vmlinux' failed The fix is similar to 1658f914ff91c3bf ("MIPS: microMIPS: Disable LL/SC and fix linker bug.")
