Also ensure OMAP clocksource read functions are marked notrace as

Jeremy Kerr 0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

This patch adds spi->mode support for the AMBA pl022 driver and
allows spidev to correctly alter SPI modes. Unused fields used in
the pl022 header file for the pl022_config_chip have been removed.

The ab8500 client driver selects the data transfer size instead
of the platform data.

For platforms that use the amba pl022 driver, the unused fields
in the controller data structure have been removed and the .mode
field in the SPI board info structure is used instead.

Linus Walleij 379aae5d6c ARM: 6295/1: fix U300 apb_pclk split
This fixes a regression due to the new apb_pclk stuff in the U300
platform, makes it run by splitting the apb clock off the single
UART clocks. For the MMCI and PL022 clocks we don't split them:
these are actually hardwired to the same clock terminal and will
thus simply have a double reference count and will be referenced
twice.

We also move clock registration to .init_irq() so they are
available early enough for probing to be successful and remove the
earlier quirk to clock primecells during PrimeCell registration.

Linus Walleij 1dbd30e989 ARM: 6225/1: make TCM allocation static and common for all archs
This changes the TCM handling so that a fixed area is reserved at
0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but
XScale does not have TCM so the mechanisms are mutually exclusive.

This change is needed to make TCM detection more dynamic while
still being able to compile code into it, and is a must for the
unified ARM goals: the current TCM allocation at different places
in memory for each machine would be a nightmare if you want to
compile a single image for more than one machine with TCM so it
has to be nailed down in one place.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Linus Walleij 7666c17e2b [ARM] 5535/1: U300 Makefile.boot
The Makefile.boot file for the U300 port. This will compile the
kernel for different ZRELADDR depending on the location of
physical RAM in the chosen configuration.

Russell King ed31b2dfad [ARM] make U300 clk_set_rate() return a _real_ errno
Another stupid instance of "return -1"-ism.

Linus Walleij f7a9a4d782 [ARM] 5510/1: U300 GPIO debug and init fixes
This moves the GPIO driver away from using __devinit and __devexit
It also removes all printk() in favor of using dev_* print macros
on pdev->dev struct instead. Surplus prints are removed, and the
platform_device_probe() function is used instead of putting a
.probe function in the platform driver struct.

Linus Walleij bb3cee2b35 [ARM] 5473/1: U300 core machine support
This adds core support for the ST-Ericsson U300 series
platforms: U300, U330, U335 and U365. Supports memory
mappings, interrupt controller, system timer (clocksource
and clockevents), and binds to the existing drivers for
the PrimeCells used in this design: PL190 (VIC), PL180
(MMC/SD host) and PL011 (UART). This is intented to serve
as starting point for our mainling work, more patches to
follow.

Linus Walleij bd41b99d46 [ARM] 5471/2: U300 GPIO and PADMUX support
This adds GPIO and PADMUX headers and implementation for
the U300 platform. This is an implementation in isolation
that depend on later patches in this series to plug into
the framework.

Linus Walleij fa59440d0c [ARM] 5470/1: U300 register definitions
This adds registers, interrupt numbers and IO mappings
for the U300 series platforms core support, including
basic block offsets and registers definitions for the
system controller.
