355e8e8d1b m68knommu: fix invalid flags on coldfire pit clocksource
The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource.  Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.

This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource.  This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).

588baeac38 m68knommu: add uboot commandline argument passing support
This patch adds m68knommu support for getting the kernel command line
arguments from uboot, including the passing of an initrd image from uboot.

We use this on a 5270/5271 based board, and have used it on the 5271evb
development board.  It is based on a patch found in the linux-2.6-denx
git tree, although that tree seems to have had lots of other changes
since which are not in the main Linus kernel.  I believe this will work
on all coldfires, although other m68knommu might be missing the _init_sp
stuff in head.S as far as I can tell.  I only have the coldfire to
test on.

cdd6c482c9 perf: Do the big rename: Performance Counters -> Performance Events
Bye-bye Performance Counters, welcome Performance Events!

In the past few months the perfcounters subsystem has grown out its
initial role of counting hardware events, and has become (and is
becoming) a much broader generic event enumeration, reporting, logging,
monitoring, analysis facility.

Naming its core object 'perf_counter' and naming the subsystem
'perfcounters' has become more and more of a misnomer. With pending
code like hw-breakpoints support the 'counter' name is less and
less appropriate.

All in one, we've decided to rename the subsystem to 'performance
events' and to propagate this rename through all fields, variables
and API names. (in an ABI compatible fashion)

The word 'event' is also a bit shorter than 'counter' - which makes
it slightly more convenient to write/handle as well.

Thanks goes to Stephane Eranian who first observed this misnomer and
suggested a rename.

User-space tooling and ABI compatibility is not affected - this patch
should be function-invariant. (Also, defconfigs were not touched to
keep the size down.)

This patch has been generated via the following script:

  FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

  sed -i \
    -e 's/PERF_EVENT_/PERF_RECORD_/g' \
    -e 's/PERF_COUNTER/PERF_EVENT/g' \
    -e 's/perf_counter/perf_event/g' \
    -e 's/nb_counters/nb_events/g' \
    -e 's/swcounter/swevent/g' \
    -e 's/tpcounter_event/tp_event/g' \
    $FILES

  for N in $(find . -name perf_counter.[ch]); do
    M=$(echo $N | sed 's/perf_counter/perf_event/g')
    mv $N $M
  done

  FILES=$(find . -name perf_event.*)

  sed -i \
    -e 's/COUNTER_MASK/REG_MASK/g' \
    -e 's/COUNTER/EVENT/g' \
    -e 's/\<event\>/event_id/g' \
    -e 's/counter/event/g' \
    -e 's/Counter/Event/g' \
    $FILES

... to keep it as correct as possible. This script can also be
used by anyone who has pending perfcounters patches - it converts
a Linux kernel tree over to the new naming. We tried to time this
change to the point in time where the amount of pending patches
is the smallest: the end of the merge window.

Namespace clashes were fixed up in a preparatory patch - and some
stylistic fallout will be fixed up in a subsequent patch.

( NOTE: 'counters' are still the proper terminology when we deal
  with hardware registers - and these sed scripts are a bit
  over-eager in renaming them. I've undone some of that, but
  in case there's something left where 'counter' would be
  better than 'event' we can undo that on an individual basis
  instead of touching an otherwise nicely automated patch. )

The ColdFire intc-simr interrupt controller should mask off all
interrupt sources at init time. Doing it here instead of separately
in each platform setup.

91b1b94f88 m68knommu: remove timer device interrupt setup for ColdFire 532x
With fully implemented interrupt controller code we don't need to do
the custom interrupt setup for the timer device of the ColdFire 532x.
Remove that code.

f1a59d244a m68knommu: remove interrupt masking from ColdFire pit timer
With proper interrupt controller code in place there is no need for
devices like the timers to have custom interrupt masking code.
Remove it (and the defines that go along with it).

a3d9bf1dfd m68knommu: remove unecessary interrupt level setting in ColdFire 520x setup
The new code for the interrupt controller in the ColdFire 520x takes
care of all the interrupt controller setup. No manual config of the
level registers (ICR) is required by the  platform device setup code.
So remove it.

de4cbfb599 m68knommu: remove the common interrupt controller structure
Each different m68knommu CPU interrupt controller type has its own
interrupt controller data structures now. Remove the old, and now not
used, common irq structs and init code from here.

0531d7b36b m68knommu: complete interrupt controller code for the 68360 CPU
Define the interrupt controller structures along with the interrupt
controller code for the 68360 CPU. This brings the interrupt setup
and control into one place for this CPU family.

33a21263bf m68knommu: use common interrupt controller code for older ColdFire CPU's
The old ColdFire CPU's (5206, 5307, 5407, 5249 etc) use a simple
interrupt controller. Use common setup code for them. This addition
means that all ColdFire CPU's now have some specific type of interrupt
controller code.

With the common intc-simr interrupt controller code in place the ColdFire

interrupt masking code, and the per-device interrupt config here.

277c5e3e26 m68knommu: general interrupt controller for ColdFire 532x parts
The ColdFire 532x family of parts uses 2 of the same INTC interrupt
controlers used in the ColdFire 520x family. So modify the code to
support both parts. The extra code for the second INTC controler in
the case of the 520x is easily optimized away to nothing.
