[PATCH 1/2 4.4 Backport] MIPS: Call dump_stack() from show_regs()

by Huacai Chen

From: Paul Burton <paul.burton(a)mips.com> commit 5a267832c2ec47b2dad0fdb291a96bb5b8869315 upstream. The generic nmi_cpu_backtrace() function calls show_regs() when a struct pt_regs is available, and dump_stack() otherwise. If we were to make use of the generic nmi_cpu_backtrace() with MIPS' current implementation of show_regs() this would mean that we see only register data with no accompanying stack information, in contrast with our current implementation which calls dump_stack() regardless of whether register state is available. In preparation for making use of the generic nmi_cpu_backtrace() to implement arch_trigger_cpumask_backtrace(), have our implementation of show_regs() call dump_stack() and drop the explicit dump_stack() call in arch_dump_stack() which is invoked by arch_trigger_cpumask_backtrace(). This will allow the output we produce to remain the same after a later patch switches to using nmi_cpu_backtrace(). It may mean that we produce extra stack output in other uses of show_regs(), but this: 1) Seems harmless. 2) Is good for consistency between arch_trigger_cpumask_backtrace() and other users of show_regs(). 3) Matches the behaviour of the ARM & PowerPC architectures. Marked for stable back to v4.9 as a prerequisite of the following patch "MIPS: Call dump_stack() from show_regs()".

Linux 4.4.142

I'm announcing the release of the 4.4.142 kernel.

[PATCH] ACPI: save NVS memory for ASUS 1025C laptop

by Willy Tarreau

Every time I tried to upgrade my laptop from 3.10.x to 4.x I faced an issue by which the fan would run at full speed upon resume. Bisecting it showed me the issue was introduced in 3.17 by commit 821d6f0359b0 (ACPI / sleep: Do not save NVS for new machines to accelerate S3). This code only affects machines built starting as of 2012, but this Asus 1025C laptop was made in 2012 and apparently needs the NVS data to be saved, otherwise the CPU's thermal state is not properly reported on resume and the fan runs at full speed upon resume. Here's a very simple way to check if such a machine is affected : # cat /sys/class/thermal/thermal_zone0/temp 55000 ( now suspend, wait one second and resume ) # cat /sys/class/thermal/thermal_zone0/temp 0 (and after ~15 seconds the fan starts to spin) Let's apply the same quirk as commit cbc00c13 (ACPI: save NVS memory for Lenovo G50-45) and reuse the function it provides. Note that this commit was already backported to 4.9.x but not 4.4.x.

As such, we should avoid dealing with vport representors if not being esw manager. While here, make sure to disallow eswitch switchdev related setups through devlink if we are not esw managers.
