This is a note to let you know that I have just added a patch titled ARM: SoCFPGA: Fix secondary CPU startup in thumb2 kernel to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: https://git.launchpad.net/~canonical-kernel/linux/+git/linux-stable-ckt/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt21. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From 8a3a98eec9f6989a095e668eb10fe2e393f77b91 Mon Sep 17 00:00:00 2001 From: Sascha Hauer <s.hauer@pengutronix.de> Date: Wed, 20 Apr 2016 13:34:31 +0000 Subject: ARM: SoCFPGA: Fix secondary CPU startup in thumb2 kernel commit 5616f36713ea77f57ae908bf2fef641364403c9f upstream. The secondary CPU starts up in ARM mode. When the kernel is compiled in thumb2 mode we have to explicitly compile the secondary startup trampoline in ARM mode, otherwise the CPU will go to Nirvana.
