      memcg: revert fix to mapcount check for this release · be22aece
      Hugh Dickins authored
      Respectfully revert commit e6ca7b89 "memcg: fix mapcount check
      in move charge code for anonymous page" for the 3.3 release, so that
      it behaves exactly like releases 2.6.35 through 3.2 in this respect.
      
      Horiguchi-san's commit is correct in itself, 1 makes much more sense
      than 2 in that check; but it does not go far enough - swapcount
      should be considered too - if we really want such a check at all.
      
      We appear to have reached agreement now, and expect that 3.4 will
      remove the mapcount check, but had better not make 3.3 different.

      x86: Derandom delay_tsc for 64 bit · a7f4255f
      Thomas Gleixner authored
      Commit f0fbf0ab ("x86: integrate delay functions") converted
      delay_tsc() into a random delay generator for 64 bit.  The reason is
      that it merged the mostly identical versions of delay_32.c and
      delay_64.c.  Though the subtle difference of the result was:
      
       static void delay_tsc(unsigned long loops)
       {
      -	unsigned bclock, now;
      +	unsigned long bclock, now;
      
      Now the function uses rdtscl() which returns the lower 32bit of the
      TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64
      bit this fails when the lower 32bit are close to wrap around when
      bclock is read, because the following check
      
             if ((now - bclock) >= loops)
             	  	break;
      
      evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0
      because the unsigned long (now - bclock) of these values results in
      0xffffffff00000001 which is definitely larger than the loops
      value. That explains Tvortkos observation:
      
      "Because I am seeing udelay(500) (_occasionally_) being short, and
       that by delaying for some duration between 0us (yep) and 491us."
      
      Make those variables explicitely u32 again, so this works for both 32
      and 64 bit.

      sh-sci / PM: Avoid deadlocking runtime PM · 048be431
      Rafael J. Wysocki authored
      The runtime PM of sh-sci devices is enabled when sci_probe() returns,
      so the pm_runtime_put_sync() executed by driver_probe_device()
      attempts to suspend the device.  Then, in some situations, a
      diagnostic message is printed to the console by one of the runtime
      suspend routines handling the sh-sci device, which causes synchronous
      runtime resume to be started from the device's own runtime suspend
      callback.  This causes rpm_resume() to be run eventually, which sees
      the RPM_SUSPENDING status set by rpm_suspend() and waits for it to
      change.  However, the device's runtime PM status cannot change at
      that point, because the routine that has set it waits for the
      rpm_suspend() to return.  A deadlock occurs as a result.
      
      To avoid that make sci_init_single() increment the device's
      runtime PM usage counter, so that it cannot be suspended by
      driver_probe_device().  That counter has to be decremented
      eventually, so make sci_startup() do that before starting to
      actually use the device and make sci_shutdown() increment it
      again before returning to balance the incrementation carried out by
      sci_startup().
