Subject: ARM: at91: aic can use fast eoi handler type
The Advanced Interrupt Controller allows us to use the fast EOI handler type.
It lets us remove the Atmel specific workaround into arch/arm/kernel/irq.c
used to indicate to the AIC the end of the interrupt treatment.

From: Ludovic Desroches <ludovic.desroches@atmel.com>
Date: Thu, 21 Jun 2012 14:47:27 +0200
Subject: 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.

From c4b68520dc0ec96153bc0d87bca5ffba508edfcf Mon Sep 17 00:00:00 2001
From: Ludovic Desroches <ludovic.desroches@atmel.com>
Date: Wed, 30 May 2012 10:01:09 +0200
Subject: ARM: at91: add AIC5 support
The number of lines of AIC5 has increased from 32 to 128. Due to this
increase, a source select register has been introduced for the interrupt
line selection. Moreover, register mapping has been changed. For that reasons,
we need some dedicated callbacks for AIC5.
Power management is also concerned by these changes. On suspend, we can't get
the whole interrupt mask register as before, we have to read this register 128
times. To reduce this overhead, a snapshot of the whole IMR is maintained.

Subject: 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
