Pull powerpc merge from Benjamin Herrenschmidt:
"Here's the powerpc batch for this merge window. It is going to be a
bit more nasty than usual as in touching things outside of
arch/powerpc mostly due to the big iSeriesectomy :-) We finally got
rid of the bugger (legacy iSeries support) which was a PITA to
maintain and that nobody really used anymore.
Here are some of the highlights:
- Legacy iSeries is gone. Thanks Stephen ! There's still some bits
and pieces remaining if you do a grep -ir series arch/powerpc but
they are harmless and will be removed in the next few weeks
hopefully.
- The 'fadump' functionality (Firmware Assisted Dump) replaces the
previous (equivalent) "pHyp assisted dump"... it's a rewrite of a
mechanism to get the hypervisor to do crash dumps on pSeries, the
new implementation hopefully being much more reliable. Thanks
Mahesh Salgaonkar.
- The "EEH" code (pSeries PCI error handling & recovery) got a big
spring cleaning, motivated by the need to be able to implement a
new backend for it on top of some new different type of firwmare.
The work isn't complete yet, but a good chunk of the cleanups is
there. Note that this adds a field to struct device_node which is
not very nice and which Grant objects to. I will have a patch soon
that moves that to a powerpc private data structure (hopefully
before rc1) and we'll improve things further later on (hopefully
getting rid of the need for that pointer completely). Thanks Gavin
Shan.
- I dug into our exception & interrupt handling code to improve the
way we do lazy interrupt handling (and make it work properly with
"edge" triggered interrupt sources), and while at it found & fixed
a wagon of issues in those areas, including adding support for page
fault retry & fatal signals on page faults.
- Your usual random batch of small fixes & updates, including a bunch
of new embedded boards, both Freescale and APM based ones, etc..."
I fixed up some conflicts with the generalized irq-domain changes from
Grant Likely, hopefully correctly.

This is the introduction of this framework. This part

open, release and write functionality as defined in
the simplest watchdog API). Extra functionality will

Remove Kconfig regression caused by commit
a4616153de "watchdog: hpwdt: build hpwdt as
module by default with NMI_DECODING enabled"
With the above change applied, hpwdt will be enabled unconditionally by just
entering the Watchdog subscreen in menuconfig. Since this driver is not
essential to boot any box it should remain disabled until it gets manually
enabled, just like all other drivers.

- Moves boot parameter checks from intel_scu_open() to

The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout
value in the code based on whether it's a Freescale Book-E part of not.
Instead of having hard-coded values in the driver, make it a Kconfig
option.
As newer chips gets faster, the current default values become less
appropriate, since the timeout sometimes occurs before the kernel finishes
booting. Making the value a Kconfig option allows BSPs to configure a new
value without requiring the wdt_period command-line parameter to be set.

The mpc8xxx_wdt driver is using two registers: SWSRR to push magic
numbers, and SWCRR to control the watchdog. Both registers are available
on the MPC8xx, and seem to have the same offsets and semantics as in
MPC83xx/MPC86xx watchdogs. The only difference is prescale value. So
this driver simply works on the MPC8xx CPUs.
One quirk is needed for the MPC8xx, though. It has small prescale value
and slow CPU, so the watchdog resets board prior to the driver has time to
load. To solve this we should split initialization in two steps: start
ping the watchdog early, and register the watchdog userspace interface
later.
MPC823 seem to be the first CPU in MPC8xx line, so we use fsl,mpc823-wdt
compatible matching.

Rename the driver because now we support some MPC86xx processors.
There are no changes to the mpc83xx_wdt.c file, yet. When possible, we do
file renames and changes separately (because Linus once asked so, because
it helps git to track the renamed files).

On MPC86xx the watchdog could be enabled only at power-on-reset, and could
not be disabled afterwards. We must ping the watchdog from the kernel
until the userspace handles it.
MPC83xx CPUs are only differ in a way that watchdog could be disabled
once, but after it was enabled via software it becomes just the same as
MPC86xx.
Thus, to support MPC86xx I added the kernel timer which pings the watchdog
until the userspace opens it.
Since we implemented the timer, now we're able to implement proper
handling for the CONFIG_WATCHDOG_NOWAYOUT case, for MPC83xx and MPC86xx.
Also move the probe code into subsys_initcall, because we want start
pinging the watchdog ASAP, and misc devices are available in
subsys_initcall.

Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.
There also seems to be noone willing to bring this port back into a usable
state.
This patch therefore removes the v850 port.
If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.

Add a watchdog timer based on the MFGPT timers in the CS5535/CS5536
companion chips to the AMD Geode GX and LX processors. Only caveat
is that the BIOS must provide at least a one free timer, and most
do not.

Hp is providing a Hardware WatchDog Timer driver that will only work with the
specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer
will generate a Non-maskable Interrupt (NMI) 9 seconds before physically
resetting the server, by removing power, so that the event can be logged to
the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory
(NVRAM). The logging of the event is performed using the HP ProLiant ROM via
an Industry Standard access known as a BIOS Service Directory Entry.

These are derivatives of the AT32AP7000 chip, which means that most of
the code stays the same. Rename a few files, functions, definitions
and config symbols to reflect that they apply to all AP700x chips, and
exclude some platform devices from chips where they aren't present.

ICP's Wafer 5823 SBC has, as far as I can tell, the same WDT as many,
if not all ICP's SBC's (that do have a WDT). I have tested it with
several boards, including Rocky 4783, Rocky 3703 and Rocky 3782.
I propose a rename of the Wafer 5823 watchdog timer driver
to something like "IPC (SBC) Watchdog Timer", to reflect that it
works with other IPC boards (maybe even all of them).
