[PATCH 2/2] arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h

From: AKASHI Takahiro
Date: Fri Feb 07 2014 - 05:12:33 EST

kernel/seccomp.c includes linux/compat.h and, indicrectly, asm/compat.h
via asm/syscall.h. Due to the duplicated definition of is_compat_task,
compiling this file will fail in the case of !CONFIG_COMPAT.
This patch makes the definition in asm/compat.h valid only if necessary.
