On a large machine I noticed the columns of /proc/interrupts failed to line up
with the header after CPU9. At sufficiently large numbers of CPUs it becomes
impossible to line up the CPU number with the counts.
While fixing this I noticed x86 has a number of updates that we may as well
pull in.
I often get asked if BAD interrupts are really bad. On some boxes (eg
IBM machines running a hypervisor) there are valid cases where are
presented with an interrupt that is not for us. These cases are common
enough to show up as thousands of BAD interrupts a day.

With NO_HZ it is useful to know how often the decrementer is going off. The

Format strings that are continued with \ are frequently misused.
Change them to use mostly single line formats, some longer than 80 chars.
Fix a few miscellaneous typos at the same time.

desc-affinity doesn't exit in that case. Let's use a macro for
the UP variant of get_irq_server(), it's the easiest way, avoids
evaluating arguments.

Hi Linus !
Here are some more defconfig updates that I missed before LCA and a
few PCI related fixes, some of them actually fixing regressions and
one of them (the 4xx one) trivial enough that's really not worth
delaying it.
Grant, I've updated this for your current test-devicetree branch.
Please apply.
Currently when processing flattened device trees, the kernel expects
the phandle in a property called linux,phandle. The ePAPR spec -

So I'm about to do a proper -next branch for the next round (it's about
time !). I'll probably push a handful or two of things in my 'test'
branch tonight, which are then going to hit -next in a day or two if
nobody complains.
There's more to pickup though.
However, the bulk of the stuff pending
PowerPC is currently using asm-generic/hardirq.h which statically allocates an
NR_CPUS irq_stat array. Switch to an arch specific implementation which uses
per cpu data:
On a kernel with NR_CPUS=1024, this saves quite a lot of memory:
textdata bss dec hexfilename
With NO_HZ it is useful to know how often the decrementer is going off. The
patch below adds an entry for it and also adds it into the /proc/stat
summaries.

Right now we allocate a cacheline sized NR_CPUS array for xics IPI
communication. Use DECLARE_PER_CPU_SHARED_ALIGNED to put it in percpu
data in its own cacheline since it is written to by other cpus.

__devinit[data] has not yet been used for all initialization functions

been renamed to mpc_i2c_data, which is even the better name.

The setclock initialization functions have been renamed to setup
because I2C interrupts must be enabled for the MPC512x. This requires
to handle fsl,preserve-clocking in a slighly different way. Also,
the old settings are now reported calling dev_dbg(). For
