820d41cf0c ARM: cleanups of io includes
Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
 moving some of the oft-repeated macros to a common location and removing a bunch of
 boiler plate. This is another step closer to a common zImage for multiple platforms.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

Pull #1 ARM updates from Russell King:
 "This one covers stuff which Arnd is waiting for me to push, as this is
  shared between both our trees and probably other trees elsewhere.

  Essentially, this contains:
   - AMBA primecell device initializer updates - mostly shrinking the
     size of the device declarations in platform code to something more
     reasonable.
   - Getting rid of the NO_IRQ crap from AMBA primecell stuff.
   - Nicolas' idle cleanups.  This in combination with the restart
     cleanups from the last merge window results in a great many

475c77edf8 Merge branch 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci
Pull PCI changes (including maintainer change) from Jesse Barnes:
 "This pull has some good cleanups from Bjorn and Yinghai, as well as
  some more code from Yinghai to better handle resource re-allocation
  when enabled.

  There's also a new initcall_debug feature from Arjan which will print
  out quirk timing information to help identify slow quirks for fixing
  or refinement (Yinghai sent in a few patches to do just that once the
  new debug code landed).

  Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
  He's been a core PCI and Linux contributor for some time now, and has
  kindly volunteered to take over.  I just don't feel I have the time
  for PCI review and work that it deserves lately (I've taken on some
  other projects), and haven't been as responsive lately as I'd like, so
  I approached Bjorn asking if he'd like to manage things.  He's going
  to give it a try, and I'm confident he'll do at least as well as I
  have in keeping the tree managed, patches flowing, and keeping things
  stable."

resource fixup cleanups clashing with list handling cleanup, ppc iseries
removal clashing with pci_probe_only cleanup etc)

Remove the now empty arch_reset() from all the mach/system.h includes,

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove

The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.

The sysdev code will be going away soon, so this include needs to be
removed no matter what.

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart.  Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.

This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

639da5ee37 ARM: add an extra temp register to the low level debugging addruart macro
Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.
