7034228792 MIPS: Whitespace cleanup. 
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

5a4a4ad851 MIPS: Mark cascade and low level interrupts IRQF_NO_THREAD 
Mark interrupts with no_action handler, cascade interrupts, low level
interrupts (bus error, halt ..) with IRQF_NO_THREAD to exclude them
from forced threading.

ca4d3e6746 MIPS: Add missing #inclusions of <linux/irq.h> 
Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should
really include it.  Note that this can replace #inclusions of <asm/irq.h>.

This is required for the patch to sort out irqflags handling function naming to
compile on MIPS.

The problem is that these files require access to things like setup_irq() -
which isn't available by #including <linux/interrupt.h>

c2d5b5e525 MIPS: SNI: Correct NULL test 
Test the value that was just allocated rather than the previously tested one.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
expression *x;
expression e;
identifier l;
@@

if (x == NULL || ...) {
    ... when forall
    return ...; }
... when != goto l;
    when != x = e
    when != &x
*x == NULL
// </smpl>

1a8a51004a cpumask: remove references to struct irqaction's mask field. 
Impact: cleanup

It's unused, since about 1995.  So remove all initialization of it in
preparation for actually removing the field.

231a35d372 [MIPS] RM: Collected changes 
- EISA support for non PCI RMs (RM200 and RM400-xxx). The major part
  is the splitting of the EISA and onboard ISA of the RM200, which
  makes the EISA bus on the RM200 look like on other RMs.
- 64bit kernel support
- system type detection is now common for big and little endian
- moved sniprom code to arch/mips/fw
- added call_o32 function to arch/mips/fw/lib, which uses a private
  stack for calling prom functions
- fix problem with ISA interrupts, which makes using PIT clockevent
  possible

06cf5583fd [MIPS] SNI RM updates 
- use RTC_CLASS instead of GEN_RTC
- get rid of ds1216 in favour of a RTC_CLASS driver
- use correct console device for older RM400
- use physical addresses for 82596 device
- use 128 byte L1 cache line size (this is needed because most of the
  SNI caches are using 128 L2 cache lines)
