ARC: Delete stale barrier.h
Commit 93ea02bb8435 ("arch: Clean up asm/barrier.h implementations")
wired generic barrier.h for ARC, but failed to delete the existing file.
In 3.15, due to rcupdate.h updates, this causes a build breakage on ARC:
CC arch/arc/kernel/asm-offsets.s
In file included from include/linux/sched.h:45:0,
from arch/arc/kernel/asm-offsets.c:9:
include/linux/rculist.h: In function __list_add_rcu:
include/linux/rculist.h:54:2: error: implicit declaration of function smp_store_release [-Werror=implicit-function-declaration]
rcu_assign_pointer(list_next_rcu(prev), new);
