66f03c614c ARM: device tree work
Most of these patches convert code from using static platform data to
 describing the hardware in the device tree. This is only the first
 half of the changes for v3.4 because a lot of patches for this topic
 came in the last week before the merge window.

Quite a bit of code gets removed, and some stuff moved around, mostly
 the old samsung s3c24xx stuff. There should be no functional changes
 in this series otherwise. Some cleanups have dependencies on other
 arm-soc branches and will be sent in the second round.

5375871d43 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
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 patch addresses such an issue by calling request_irq later.

Error handling in probe function and calling oder in remove function are
also revised accordingly.

0d098587ce watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing (part 2)
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver

The previous patch breaks reset watchdog behaviour on the older hardware.
It is therefor better to make sure that the behaviour for older hardware (<=ICH5 or
6300ESB) is preserved and that the behaviour for newer hardware is changed.
We therefor use the iTCO_version to see if we need the clearing of the SMI_TCO_EN
bit in the SMI_EN register.

So the new behaviour becomes:
turn_SMI_watchdog_clear_off=0 -> Do not turn off SMI clearing watchdog.
turn_SMI_watchdog_clear_off=1 -> Turn off SMI clearing watchdog when iTCO_version=1
				 (ICHO till ICH5 + 6300ESB only)
turn_SMI_watchdog_clear_off=2 -> Turn off SMI clearing watchdog.
