From d8c6d8b877cb2a216e933ce11954632a9daeb362 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 28 Oct 2014 12:24:20 +0000 Subject: [PATCH] arm64/dt: add machine name to kernel call stack dump output This installs the machine name as recorded by setup_machine_fdt() as dump stack arch description. This results in the string to be included in call stack dumps, as is shown here: ... Bad mode in Synchronous Abort handler detected, code 0x84000005 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.18.0-rc2+ #548 > Hardware name: linux,dummy-virt (DT) task: ffffffc07c870000 ti: ffffffc07c878000 task.ti: ffffffc07c878000 PC is at 0x0 ... Note that systems that support DMI/SMBIOS may override this later.
