Subject: [PATCH] ARM: EXYNOS: Fix build error which was from common.c and old
 cpu.c

This fixes build error and wrong merge conflicts.
arch/arm/mach-exynos/common.c: In function 'exynos4_gic_irq_fix_base':
arch/arm/mach-exynos/common.c:393: error: dereferencing pointer to incomplete type
arch/arm/mach-exynos/common.c:396: error: dereferencing pointer to incomplete type

Following A and B have been created from different base and the build
error was casued in the process of merging and should be fixed in this
merge window.

A. commit db0d4db ("ARM: gic: allow GIC to support non-banked setups"),
  commit 4e44d2c ("ARM: exynos4: convert to CONFIG_MULTI_IRQ_HANDLER")
  and commit 69676c3 ("ARM: exynos4: Fix build error due to
  'gic_bank_offset' undeclared")

B. commit cc511b8 ("ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/
  common.[ch]") introduced common.[ch]")

Hi Russell,

This should be fixed, I'm sending this to patch system.
If you're ok with this, please pick it up for this merge window.

Thanks.
