      Linus Torvalds authored
      Pull sound fixes from Takashi Iwai:
       "Well, this one became unpleasantly larger than previous pull requests,
        but it's a kind of usual pattern: now it contains a collection of ASoC
        fixes, and nothing to worry too much.
      
        The fixes for ASoC core (DAPM, DPCM, topology) are all small and just
        covering corner cases. The rest changes are driver-specific, many of
        which are for x86 platforms and new drivers like STM32, in addition to
        the usual fixups for HD-audio"

      iommu/amd: Set exclusion range correctly · 3c677d20
      Joerg Roedel authored
      The exlcusion range limit register needs to contain the
      base-address of the last page that is part of the range, as
      bits 0-11 of this register are treated as 0xfff by the
      hardware for comparisons.
      
      So correctly set the exclusion range in the hardware to the
      last page which is _in_ the range.

      perf/core: Fix perf_event_disable_inatomic() race · 1d54ad94
      Peter Zijlstra authored
      Thomas-Mich Richter reported he triggered a WARN()ing from event_function_local()
      on his s390. The problem boils down to:
      
      	CPU-A				CPU-B
      
      	perf_event_overflow()
      	  perf_event_disable_inatomic()
      	    @pending_disable = 1
      	    irq_work_queue();
      
      	sched-out
      	  event_sched_out()
      	    @pending_disable = 0
      
      					sched-in
      					perf_event_overflow()
      					  perf_event_disable_inatomic()
      					    @pending_disable = 1;
      					    irq_work_queue(); // FAILS
      
      	irq_work_run()
      	  perf_pending_event()
      	    if (@pending_disable)
      	      perf_event_disable_local(); // WHOOPS
      
      The problem exists in generic, but s390 is particularly sensitive
      because it doesn't implement arch_irq_work_raise(), nor does it call
      irq_work_run() from it's PMU interrupt handler (nor would that be
      sufficient in this case, because s390 also generates
      perf_event_overflow() from pmu::stop). Add to that the fact that s390
      is a virtual architecture and (virtual) CPU-A can stall long enough
      for the above race to happen, even if it would self-IPI.
      
      Adding a irq_work_sync() to event_sched_in() would work for all hardare
      PMUs that properly use irq_work_run() but fails for software PMUs.
      
      Instead encode the CPU number in @pending_disable, such that we can
      tell which CPU requested the disable. This then allows us to detect
      the above scenario and even redirect the IPI to make up for the failed
      queue.
