      Haswell and Broadwell can be configured to hash the channel
      interleave function using bits [27:12] of the physical address.
      
      On those processor models we must check to see if hashing is
      enabled (bit21 of the HASWELL_HASYSDEFEATURE2 register) and
      act accordingly.

      I switched the "sck_way" variable from holding the log2 value read
      from the h/w to instead be the actual number. Unfortunately it
      is needed in log2 form when used to shift the address.

      No more major fixes left. Out of the 6 fixes we have
      here, 4 are on dwc3.
      
      The most important is the memory leak fix in
      dwc3/debugfs.c. We also have a fix for PHY handling
      in suspend/resume and a fix for dwc3-omap's error
      handling.
      
      Suspend/resume also had the potential to trigger a
      NULL pointer dereference on dwc3; that's also fixed
      now.
      
      Our good ol' ffs function gets a use-after-free fix
      while the generic composite.c layer has a robustness
      fix by making sure reserved fields of a possible SSP
      device capability descriptor is cleared to 0.

      x86/mm/xen: Suppress hugetlbfs in PV guests · 103f6112

      Huge pages are not normally available to PV guests. Not suppressing

      cpu/hotplug: Fix rollback during error-out in __cpu_disable() · 3b9d6da6
      Sebastian Andrzej Siewior authored
      The recent introduction of the hotplug thread which invokes the callbacks on
      the plugged cpu, cased the following regression:
      
      If takedown_cpu() fails, then we run into several issues:
      
       1) The rollback of the target cpu states is not invoked. That leaves the smp
          threads and the hotplug thread in disabled state.
      
       2) notify_online() is executed due to a missing skip_onerr flag. That causes
          that both CPU_DOWN_FAILED and CPU_ONLINE notifications are invoked which
          confuses quite some notifiers.
      
       3) The CPU_DOWN_FAILED notification is not invoked on the target CPU. That's
          not an issue per se, but it is inconsistent and in consequence blocks the
          patches which rely on these states being invoked on the target CPU and not
          on the controlling cpu. It also does not preserve the strict call order on
          rollback which is problematic for the ongoing state machine conversion as
          well.
      
      To fix this we add a rollback flag to the remote callback machinery and invoke
      the rollback including the CPU_DOWN_FAILED notification on the remote
      cpu. Further mark the notify online state with 'skip_onerr' so we don't get a
      double invokation.
      
      This workaround will go away once we moved the unplug invocation to the target
      cpu itself.

        	target cpu ]

      objtool: Fix Makefile to properly see if libelf is supported · c2bb9e32
      Steven Rostedt authored
      When doing a make allmodconfig, I hit the following compile error:

        compilation terminated.
        ...
      
      Digging into it, it appears that the $(shell ..) command in the Makefile does
      not give the proper result when it fails to find -lelf, and continues to
      compile objtool.
      
      Instead, use the "try-run" makefile macro to perform the test. This gives a
      proper result for both cases.
