[RFC PATCH 00/10] Make mach/irqs.h optional

[Rob Herring]

From: Rob Herring <rob.herring at calxeda.com>

This series removes the include of mach/irqs.h from asm/irq.h when
SPARSE_IRQ is selected. Platforms which select SPARSE_IRQ have been
updated.

This breaks platforms where SPARSE_IRQ is user selectable. This is on
purpose so that SPARSE_IRQ gets properly supported. We could push
HAVE_SPARSE_IRQ option down to the platforms that select it if that is
preferred. But as recent experience has shown, perhaps breaking platforms
is the only way to get some platforms updated.

Platforms either need to set nr_irqs in their machine desc or all irqchips
used by a platform need to allocate their irq_descs. There cannot be a
mixture. Once this is done, the platforms can select SPARSE_IRQ. shmobile
does the latter, and mnp and pxa do the former.

I've built all defconfigs, but don't have any of the affected platforms to
boot test. I think shmobile is the main platform that needs testing here.
