Pull ARM SoC cleanups from Arnd Bergmann:
"These cleanup patches are mainly move stuff around and should all be
harmless. They are mainly split out so that other branches can be
based on top to avoid conflicts.
Notable changes are:
- We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used (Uwe Kleine-König)
- The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions (Kumar Gala)
- A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
- Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
- mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
- at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people)"

Pull ARM SoC non-critical bug fixes from Arnd Bergmann: "Lots of isolated bug fixes that were not found to be important enough to be submitted before the merge window or backported into stable kernels.

Pull ARM changes from Russell King:
- Perf updates from Will Deacon:
- Support for Qualcomm Krait processors (run perf on your phone!)
- Support for Cortex-A12 (run perf stat on your FPGA!)
- Support for perf_sample_event_took, allowing us to automatically decrease
the sample rate if we can't handle the PMU interrupts quickly enough
(run perf record on your FPGA!).
- Basic uprobes support from David Long:
This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
- ARMv7M (microcontroller) updates from Uwe Kleine-König
- OMAP DMA updates (recently added Vinod's Ack even though they've been
sitting in linux-next for a few months) to reduce the reliance of
omap-dma on the code in arch/arm.
- SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan
- Support for Cortex-A12 CPU
- Align support for ARMv6 with ARMv7 so they can cooperate better in a
single zImage.
- Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support.
- Removal of IRQ_DISABLED from various ARM files
- Improved efficiency of virt_to_page() for single zImage
- Patch from Ulf Hansson to permit runtime PM callbacks to be available for
AMBA devices for suspend/resume as well.
- Finally kill asm/system.h on ARM.

Export the DMA register information from the SoC specific data, such that we can access the registers directly in omap-dma.c, mapping the register region ourselves as well. Rather than calculating the DMA channel register in its entirety for each access, we pre-calculate an offset base address for the allocated DMA channel and then just use the appropriate register offset.

The omap_system_dma_plat_info structure is only seven words, it's not worth the expense of kmalloc()'ing backing store for this only to release it later. Note that platform_device_add_data() copies the data anyway. Clean up the initialisation of this structure - we don't even need code to initialise most of this structure. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
This really needs to be there, because otherwise the plat-omap code can kfree() this data structure, and then re-use the pointer later. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
There's no need for this to be a global variable; move it into the errata configuration function instead. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
We can do much better with this by using a structure to describe each register, rather than code. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
dma_stride and dma_common_ch_start are only ever initialised to one known value at initialisation, and are private to each of these files. There's no point these being variables at all. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
