OK here's I've queued. I updated the comments a bit.
Will also post a similar change for omap1.

Subject: [PATCH] omap2+: Fix unused variable warning for omap_irq_base
Commit 5d190c40100793a6dfc37bf325677c10f3c80edf
(omap2+: Initialize omap_irq_base for entry-macro.S from
platform code) simplified the handling of omap_irq_base
for multi-omap builds. However, this patch also introduced
a build warning for !MULTI_OMAP2 builds:
arch/arm/mach-omap2/io.c: In function 'omap_irq_base_init':
arch/arm/mach-omap2/io.c:322: warning: unused variable 'omap_irq_base'
Fix this by removing the ifdef. Also simplify things further
by moving omap_irq_base out of entry-macro.S.
