kernel/seccomp.c includes linux/compat.h and, indicrectly, asm/compat.h via asm/syscall.h. Due to the duplicated definitions of is_compat_task, compiling this file will fail in the case of !CONFIG_COMPAT. So this patch 1) removes is_compat_task() definition from asm/compat.h 2) replaces asm/compat.h to linux/compat.h in kernel/*.c
