As compiler-gcc3.h is trivial, what about integrating

I think that's the right thing to do yes.

Hi Wim, all,
The purpose of this patchset is to add a platform data structure for the
max63xx_wdt driver in order to setup the device in a platform code. This is
especially handy if the driver is built-in and/or the device registers aren't
memory mapped.
First, fix the Kconfig entry to

Hi,
Here are two patches to bring support for a new hardware based on SAM9G25 SoC.
The first one adds the PIN controller definition for PWM0.
The second defines the new board.
Changes since v1:
- drop useless comments
- move pwm0 pinctrl's node close to tcb0
- drop ek boards from compatible
Defines the pinctrl configurations for PWM0.

Instead of turning all irq_work requests into lazy ones on -rt, just
move their execution from hard into soft-irq context.
This resolves deadlocks of ftrace which will queue work from arbitrary
contexts, including those that have locks held that are needed for
raising a soft-irq.

Even if you ignore the fundamental semantics of groups, there are other
problems with allowing shared contexts:
* The *_txn functions only get called on the group leader's PMU. If your
system PMU has these functions, they are not called.
