Pull arm-soc board specific changes from Olof Johansson: "While we generally attempt to get rid of board specific files and replace them with device tree based descriptions, a lot of platforms have not come that far: In shmobile, we add two new board files because their recently started effort to add DT support has not proceeded enough to use it for all of the important hardware. In Kirkwood, we are adding support for new boards with a combination of DT and board file contents in multiple cases. pxa/mmp and imx are extending support for existing board files but not adding new ones."

Pull support for new arm SoCs from Olof Johansson: "Three new system-on-chip models are supported: the st-ericsson u9540 in ux500, the sam9n12 in at91 and the emma ev2 in shmobile. Emma is a little bit special because it is completely unrelated to the classic shmobile models, but the new Renesas rmobile SoCs are a combination of things from both Emma and shmobile, so it was decided to have them all live in one directory.

The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series.

These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them.

Tied to both the Emma Mobile EV2 and the KZM9D board due to the need to switch on board in platsmp.c and the newly introduced need for static mappings.

2012-05-17ARM: 7419/1: vfp: fix VFP flushing regression on sigreturn pathWill Deacon1-12/+2
Commit ff9a184c ("ARM: 7400/1: vfp: clear fpscr length and stride bits on entry to sig handler") flushes the VFP state prior to entering a signal handler so that a VFP operation inside the handler will trap and force a restore of ABI-compliant registers. Reflushing and disabling VFP on the sigreturn path is predicated on the saved thread state indicating that VFP was used by the handler -- however for SMP platforms this is only set on context-switch, making the check unreliable and causing VFP register corruption in userspace since the register values are not necessarily those restored from the sigframe. This patch unconditionally flushes the VFP state after a signal handler. Since we already perform the flush before the handler and the flushing itself happens lazily, the redundant flush when VFP is not used by the handler is essentially a nop.

2012-05-17ARM: 7418/1: LPAE: fix access flag setup in mem_type_tableVitaly Andrianov1-1/+2
A zero value for prot_sect in the memory types table implies that section mappings should never be created for the memory type in question. This is checked for in alloc_init_section(). With LPAE, we set a bit to mask access flag faults for kernel mappings. This breaks the aforementioned (!prot_sect) check in alloc_init_section(). This patch fixes this bug by first checking for a non-zero prot_sect before setting the PMD_SECT_AF flag.

2012-05-17ARM: mach-shmobile: sh73a0: fixup PINT/IRQ16-IRQ31 irq number conflictKuninori Morimoto1-3/+31
Current IRQ16-IRQ31 irq number are located around 800 from 1ee8299a9ec1ce5137a044c7768293007b9a3267 (ARM: mach-shmobile: Use 0x3400 as INTCS vector offset) But, the PINT0/1 IRQ number are also located around 800 from 0df1a838d678fc6ab49f983a19e905f6a42297a0 (ARM: mach-shmobile: sh73a0 PINT IRQ base fix) This patch relocates PINT0/1 IRQ number to around 700 where is not used, and adds current IRQ location table in comment area.
