Support for ARM Ltd. Integrator systems depends on ARCH_MULTIPLATFORM.
As the latter selects SPARSE_IRQ, there is no need for ARCH_INTEGRATOR
to select SPARSE_IRQ.

The patch shifting the IRQ-numbering by one is a prerequisite for the two
above patches, right?

I only remember sending two patches for ep93xx:
ARM: ep93xx: make mach/ep93xx-regs.h local
ARM: ep93xx: enable SPARSE_IRQ
and have added the Tested-by tag to them now. Is there a third one
I missed?

Everything is in place now for SPARSE_IRQ. Select it and set
DAVINCI_INTC_START to NR_IRQS.
We now need to include mach/irqs.h in a couple places as it is no
longer indirectly included after selecting SPARSE_IRQ.

Now IRQ mappings are always created for all (allowed) GPIOs in gpio irqchip in
gpiochip_irqchip_add_key() which goes against the idea of SPARSE_IRQ and,
as result, leads to:
- increasing of memory consumption because of allocated IRQ descriptors most

The idea of this changes was inspired by discussion [1].
Now IRQ mappings are always created for all (allowed) GPIOs in GPIO irqchip in
gpiochip_irqchip_add_key() and this goes against the idea of SPARSE_IRQ and,

Perhaps Im being an idiot, but it looks to me like the
menu-item for SPARSE_IRQ (under General setup -> IRQ subsystem)
depends solely on MAY_HAVE_SPARSE_IRQ, but I only see *one* user
for that in the kernel now, the SuperH arch (arch/sh/Kconfig). It
