[RFC PATCH v2 7/9] arm64: allocate sys_membarrier system call number

arm64 sys_membarrier number is already wired for arm64 through asm-generic/unistd.h, but needs to be allocated separately for the 32-bit compability layer of arm64. [ Untested on this architecture. To try it out: fetch linux-next/akpm, apply this patch, build/run a membarrier-enabled kernel,
