      Pull ARM fixes from Russell King:
 "Here's my usual Sunday push, just for one revert which PeterZ hollered
  about after last weeks push.  Other than that, all seems strangely
  quiet as far as fixes go in non-platform ARM land at the moment."

      Pull powerpc fixes from Benjamin Herrenschmidt:
 "Here are a few fixes for powerpc.  Note the addition to the generic
  irq.h.  This is part of a 3-patches regression fix for mpic due to
  changes in how IRQ_TYPE_NONE is being handled.  Thomas agreed to the
  addition of the new IRQ_TYPE_DEFAULT contant, however he hasn't
  replied with an Ack to the actual patch yet.  I don't to wait much
  longer with these patches tho."

  powerpc/mpic: Properly set default triggers

      powerpc/mpic: Properly set default triggers · 446f6d06
      Benjamin Herrenschmidt authored 
      This gets rid of the unused default senses array, and replaces the
incorrect use of IRQ_TYPE_NONE with the new IRQ_TYPE_DEFAULT for
the initial set_trigger() call when mapping an interrupt.

This in turn makes us read the HW state and update the irq desc
accordingly.

      irq: Add IRQ_TYPE_DEFAULT for use by PIC drivers · 3fca40c7
      Benjamin Herrenschmidt authored 
      This is meant typically to allow a PIC driver's irq domain map() callback
to establish sane defaults for the interrupt (and make sure that the HW
and the irq_desc are in sync as far as the trigger is concerned).

The irq core may not call the set_trigger callback if it thinks the
trigger is already set to the right setting, so we need to ensure new
descriptors are properly synchronized with the hardware.

      powerpc/mpic: Fix confusion between hw_irq and virq · 3a2b4f7c
      Benjamin Herrenschmidt authored 
      mpic_is_ipi() takes a virq and immediately converts it to a hw_irq.

However, one of the two call sites calls it with a ... hw_irq. The
other call site also happens to have the hw_irq at hand, so let's
change it to just take that as an argument. Also change mpic_is_tm()
for consistency.

      powerpc/pmac: Don't add_timer() twice · 3027691e
      Benjamin Herrenschmidt authored 
      If the interrupt and the timeout happen roughly at the same
time, we can get into a situation where the timer function
is run while the interrupt has already been processed. In
this case, the timer function might end up doing an add_timer
on an already pending timer, causing a BUG_ON() to trigger.

Instead, just skip the whole timeout operation if we see that
the timer is pending. The spinlock ensures that the only way
that happens is if we already started a new operation and thus
the timeout can be ignored.

      powerpc/eeh: Fix crash caused by null eeh_dev · 2ef822c5
      Gavin Shan authored 
      The problem was reported by Anton Blanchard. While EEH error
happened to the PCI device without the corresponding device
driver, kernel crash was seen. Eventually, I successfully
reproduced the problem on Firebird-L machine with utility
"errinjct". Initially, the device driver for Emulex ethernet
MAC has been disabled from .config and force data parity on
the Emulex ethernet MAC with help of "errinjct". Eventually,
I saw the kernel crash after issueing couple of "lspci -v"
command.

The root cause behind is that the PCI device, including the
reference to the corresponding eeh device, will be removed
from the system while EEH does recovery. Afterwards, the
PCI device will be probed again and added into the system
accordingly. So it's not safe to retrieve the eeh device from
the corresponding PCI device after the PCI device has been removed
and not added again.

The patch fixes the issue and retrieve the eeh device from OF node
instead of PCI device after the PCI device has been removed.
