[PATCH] arm: arch_timer: include linux/errno.h to declare ENXIO

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

This fixes:
arch/arm/kernel/arch_timer.c: In function ‘arch_timer_sched_clock_init’:
arch/arm/kernel/arch_timer.c:55:11: error: ‘ENXIO’ undeclared (first use in this function)

Signed-off-by: Stephen Warren <swarren at nvidia.com>

tegra_defconfig builds OK, but with my local change to convert Tegra to
multi-platform, I need this fix to compile. This issue is new sometime
after next-20130211.
