2020-01-27powerpc/32: Add early stack overflow detection with VMAP stack.Christophe Leroy
To avoid recursive faults, stack overflow detection has to be performed before writing in the stack in exception prologs. Do it by checking the alignment. If the stack pointer alignment is wrong, it means it is pointing to the following or preceding page. Without VMAP stack, a stack overflow is catastrophic. With VMAP stack, a stack overflow isn't destructive, so don't panic. Kill the task with SIGSEGV instead. A dedicated overflow stack is set up for each CPU. lkdtm: Performing direct entry EXHAUST_STACK lkdtm: Calling function with 512 frame size to depth 32 ... lkdtm: loop 32/32 ... lkdtm: loop 31/32 ... lkdtm: loop 30/32 ... lkdtm: loop 29/32 ... lkdtm: loop 28/32 ... lkdtm: loop 27/32 ... lkdtm: loop 26/32 ... lkdtm: loop 25/32 ... lkdtm: loop 24/32 ... lkdtm: loop 23/32 ... lkdtm: loop 22/32 ... lkdtm: loop 21/32 ... lkdtm: loop 20/32 ...

2020-01-27thermal: brcmstb_thermal: Do not use DT coefficientsFlorian Fainelli
At the time the brcmstb_thermal driver and its binding were merged, the DT binding did not make the coefficients properties a mandatory one, therefore all users of the brcmstb_thermal driver out there have a non functional implementation with zero coefficients. Even if these properties were provided, the formula used for computation is incorrect. The coefficients are entirely process specific (right now, only 28nm is supported) and not board or SoC specific, it is therefore appropriate to hard code them in the driver given the compatibility string we are probed with which has to be updated whenever a new process is introduced. We remove the existing coefficients definition since subsequent patches are going to add support for a new process and will introduce new coefficients as well.

2020-01-27dt-bindings: Add Broadcom AVS RO thermalStefan Wahren
Since the BCM2711 doesn't have a AVS TMON block, the thermal information must be retrieved from the AVS ring oscillator block. This block is part of the AVS monitor which contains a bunch of raw sensors.
