This patch removes unitstd32.h include to avoid duplication of
"__NR_" syscall definitions.

This patch is based on AOSP commit: cfc7e99e9e3900056028a7d90072e9ea0d886f8d,
"arm64: Add __NR_* definitions for compat syscalls", which adds
__NR_* definitions to asm/unistd32.h, moves the __NR_compat_*
definitions to asm/unistd.h and removes all the explicit unistd32.h
includes apart from the one building the compat syscall table.
The aim is to have the compat __NR_* definitions available but
without colliding with the native syscall definitions (required
by lib/compat_audit.c to avoid duplicating the audit header files
between native and compat).

Because in SMP, "mrq" has race condition between below two paths:
path1: CPU0: <tasklet context>
  static void mmc_wait_data_done(struct mmc_request *mrq)
  {
    mrq->host->context_info.is_done_rcv = true;
    //
    // If CPU0 has just finished "is_done_rcv = true" in path1, and at
    // this moment, IRQ or ICache line missing happens in CPU0.
    // What happens in CPU1 (path2)?
    //
    // If the mmcqd thread in CPU1(path2) hasn't entered to sleep mode:
    // path2 would have chance to break from wait_event_interruptible
    // in mmc_wait_for_data_req_done and continue to run for next
    // mmc_request (mmc_blk_rw_rq_prep).
    //
    // Within mmc_blk_rq_prep, mrq is cleared to 0.
    // If below line still gets host from "mrq" as the result of
    // compiler, the panic happens as we traced.
    wake_up_interruptible(&mrq->host->context_info.wait);
  }

path2: CPU1: <The mmcqd thread runs mmc_queue_thread>
 static int mmc_wait_for_data_req_done(...
 {
    ...
    while (1) {
          wait_event_interruptible(context_info->wait,
                  (context_info->is_done_rcv ||
                   context_info->is_new_req));

  static void mmc_blk_rw_rq_prep(...
  {
    ...
    memset(brq, 0, sizeof(struct mmc_blk_request));

This issue happens very coincidentally; however adding mdelay(1) in
mmc_wait_data_done as below could duplicate it easily.
  static void mmc_wait_data_done(struct mmc_request *mrq)
  {
    mrq->host->context_info.is_done_rcv = true;
    mdelay(1);
    wake_up_interruptible(&mrq->host->context_info.wait);
  }
At runtime, IRQ or ICache line missing may just happen at the same place
of the mdelay(1).

This patch gets the mmc_context_info at the beginning of function, it can
avoid this race condition.

arm64: Fix deadlock scenario with smp_send_stop()

If one process calls sys_reboot and that process then stops other
CPUs while those CPUs are within a spin_lock() region we can
potentially encounter a deadlock scenario like below.

CPU 0                   CPU 1
-----                   -----
                        spin_lock(my_lock)
smp_send_stop()
 <send IPI>             handle_IPI()
                         disable_preemption/irqs
                          while(1);
 <PREEMPT>
spin_lock(my_lock) <--- Waits forever

We shouldn't attempt to run any other tasks after we send a stop
IPI to a CPU so disable preemption so that this task runs to
completion. We use local_irq_disable() here for cross-arch
consistency with x86.

arm64: Fix machine_shutdown() definition

This patch ports most of commit 19ab428f4b79 "ARM: 7759/1: decouple CPU
offlining from reboot/shutdown" by Stephen Warren from arch/arm to
arch/arm64.

machine_shutdown() is a hook for kexec. Add a comment saying so, since
it isn't obvious from the function name.

Halt, power-off, and restart have different requirements re: stopping
secondary CPUs than kexec has. The former simply require the secondary
CPUs to be quiesced somehow, whereas kexec requires them to be
completely non-operational, so that no matter where the kexec target
images are written in RAM, they won't influence operation of the
secondary CPUS,which could happen if the CPUs were still executing some
kind of pin loop. To this end, modify machine_halt, power_off, and
restart to call smp_send_stop() directly, rather than calling
machine_shutdown().

In machine_shutdown(), replace the call to smp_send_stop() with a call

thus satisfying the kexec requirements a couple paragraphs above.
