  - the following files are sourced additionally:
    + drivers/macintosh/Kconfig
      completely depends on PPC || MAC || X86

      depends on AR7 && EXPERIMENTAL (that is ARCH_MIPS)
    + drivers/xen/Kconfig
      everything depends on XEN
    + drivers/platform/Kconfig

d45a398fca Use kernel/Kconfig.preempt for ARM
before this patch ARM had it's own definition of CONFIG_PREEMPT.
Instead of that use the general definition provided in
kernel/Kconfig.preempt.

This patch changes the available options in *config.  Namely PREEMPT
isn't a stand alone bool anymore, but part of a 'choice' the
following Kconfig symbols are added:

	PREEMPT_NONE
	PREEMPT_VOLUNTARY

Selecting PREEMPT_NONE now produces exactly the code as not selecting
PREEMPT before (apart from a comment in
/sys/kernel/debug/tracing/(per_cpu/cpuX/)?trace).  The only difference
PREEMPT_VOLUNTARY does is that might_resched might reschedule.  Both
should't introduce regressions.

0d928b0b61 Complete irq tracing support for ARM
Before this patch enabling and disabling irqs in assembler code and by
the hardware wasn't tracked completly.

I had to transpose two instructions in arch/arm/lib/bitops.h because
restore_irqs doesn't preserve the flags with CONFIG_TRACE_IRQFLAGS=y

b88fb83b13 netx: Use get_irqnr_preamble to initialize base register
This patch optimizes the irq handling a bit.  Now the base register is
only computed once per irq exception instead of at least twice.
Moreover the mov+add sequence is simplified to an ldr (which might save
some cycles depending on memory timing).

9e1b32caa5 mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()

Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.

Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.

The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

808347f6a3 dmaengine: at_hdmac: add DMA slave transfers
This patch for at_hdmac adds the slave transfers capability to the Atmel DMA
controller available on some AT91 SOCs. This allow peripheral to memory and
memory to peripheral transfers with hardware handshaking.

Slave structure for controller specific information is passed through channel
private data. This at_dma_slave structure is defined in at_hdmac.h header file
and relative hardware definition are moved to this file from at_hdmac_regs.h.
Doing this we allow the channel configuration from platform definition code.

This work is intensively based on dw_dmac and several slave implementations.

dc78baa2b9 dmaengine: at_hdmac: new driver for the Atmel AHB DMA Controller
This AHB DMA Controller (aka HDMA or DMAC on AT91 systems) is availlable on
at91sam9rl chip. It will be used on other products in the future.

This first release covers only the memory-to-memory tranfer type. This is the
only tranfer type supported by this chip.  On other products, it will be used
also for peripheral DMA transfer (slave API support to come).

I used dmatest client without problem in different configurations to test it.

Full documentation for this controller can be found in the SAM9RL datasheet:

Pull the initial preempt_count value into a single

Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.

The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

574ec547c7 ARM: add support for the EET board, based on the i.MX31 pcm037 module
The "EET" variant of the pcm037 board has an OLED display, using a S6E63D6
display controller on the first SPI interface, using GPIO57 as a chip-select
for it. S6E63D6 is initialised in the boot-loader, so we only have to take care
of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a
"pcm037_variant=" kernel command line parameter to specify at boot-time which
board the kernel is running on, default is "pcm970", specify "eet" for the EET
board.

32c1ad9ab2 pcm037: add MT9T031 camera support
Add support for the MT9T031 CMOS camera sensor from Aptina to the PCM037
board. Also add two I2C iomux pin definitions, needed for pcm037. Also
remove now unneeded #ifdef CONFIG_I2C_IMX.

291e99a112 [ARM] S3C24XX: Fix use of CONFIG_S3C24XX_PWM
CONFIG_S3C24XX_PWM was defined in arch/arm/plat-s3c24xx/Kconfig but
not used anywhere else as the corresponding makefile used
CONFIG_HAVE_PWM (selected by CONFIG_S3C24XX_PWM) to compile the PWM
driver.

Change the makefile to use CONFIG_S3C24XX_PWM to compile this driver
to ensure it is only build when needed.
