Jean-Christophe PLAGNIOL-VILLARD 546c830c90 ARM: at91: fix at91_extern_irq usage for non-dt boards
Since 4b68520dc0ec96153bc0d87bca5ffba508edfcf
ARM: at91: add AIC5 support

we allocate the at91_extern_irq.

This patch makes it static and stores the non-dt extern irq in the soc
structure. It is then possible to use a at91_get_extern_irq() function
to get the value for outside of the irq driver. It is useful for passing
its value to at91_aic_init().

Arnd Bergmann 0654f4ab2b ARM: at91: fix at91x40 build
patch 738a0fd7 "ARM: at91: fix external interrupts in non-DT case"
fixed a run-time error on some at91 platforms but did not apply
the same change to at91x40, which now doesn't build.

This changes at91x40 in the same way that the other platforms
were changed.

Arnd Bergmann dca4ba4121 ARM: at91: use __iomem pointers for MMIO
ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.

Arnd Bergmann 14070ade02 ARM: at91: fix new build errors
MULTI_IRQ_HANDLER and SPARSE_IRQ are now required everywhere because
mach/irqs.h and mach/entry-macros.S are gone but the symbols are
only selected for AT91SAM9, not for the NOMMU parts.

A few files now need to include linux/io.h directly, which used to
be included through other headers that have changed.

The new at91_aic_irq_priorities variable is only used with CONFIG_OF
enabled and should not be visible otherwise.

Ludovic Desroches 8fe82a5550 ARM: at91: sparse irq support
Enable sparse irq support for multisoc image. It involves to add the
NR_IRQS_LEGACY offset to static SoC irq number definitions since NR_IRQS_LEGACY
irq descs are allocated before AIC requests irq descs allocation.
Move NR_AIC_IRQS macro to a more appropiate place with the purpose to
remove mach/irqs.h later.

Olof Johansson 86dfe446c2 ARM: fix builds due to missing <asm/system_misc.h> includes
This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.

I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.
