For future rework of try_to_wake_up() we'd like to push part of that
onto the CPU the task is actually going to run on, in order to do so we
need a generic callback from the existing scheduler IPI.
This patch introduces such a generic callback: scheduler_ipi() and
implements it as a NOP.

Now handles multiple ranges, doesn't make assumptions about interrupt
specifier format, and doesn't claim interrupts that don't correspond to an
available range.
Also has some better error checking.
The device tree binding is updated to clarify some existing assumptions.

Improve the status messages that are displayed during some operations of the
PowerPC watchdog timer driver. When the watchdog is enabled, the timeout is
displayed as a number of seconds, instead of an obscure "period". The "period"

Don't say that enable timed out when it was disable, and

This patch set provides a binding for the MPIC and implements support
for a new property, specified by that binding, called 'no-reset'.

It appears that I'm hitting an exactly the same problem with my MPC8548
rev2.0 (errata number eTSEC 49).
Considering that it's close to 3 month now since this most unfortunate
bug was reported, was there any resolution/patch that can fix it for good?
