      x86: Fix Moorestown VRTC fixmap placement · fa36e956
      Arjan van de Ven authored
      The x86 fixmaps need to be all together... unfortunately the
      VRTC one was misplaced.
      
      This patch makes sure the MRST VRTC fixmap is put prior to the
      __end_of_permanent_fixed_addresses marker.

      We need this for x86 MID platforms where GPIO interrupts are
      used. No special magic is needed so the default 1:1 behaviour
      will do nicely.

      x86, UV: Fix APICID shift for Westmere processors · 990a32d1
      Jack Steiner authored
      Westmere processors use a different algorithm for
      assigning APICIDs on SGI UV systems. The location of the
      node number within the apicid is now a function of the
      processor type.

      x86: Use PCI method for enabling AMD extended config space before MSR method · 24d9b70b
      Jan Beulich authored
      While both methods should work equivalently well for the native
      case, the Xen Dom0 case can't reliably work with the MSR one,
      since there's no guarantee that the virtual CPUs it has
      available fully cover all necessary physical ones.
      
      As per the suggestion of Robert Richter the patch only adds the
      PCI method, but leaves the MSR one as a fallback to cover new
      systems the PCI IDs of which may not have got added to the code
      base yet.
      
      The only change in v2 is the breaking out of the new CPI
      initialization method into a separate function, as requested by
      Ingo.

      x86: tsc: Prevent delayed init if initial tsc calibration failed · 29fe359c
      Thomas Gleixner authored
      commit a8760eca (x86: Check tsc available/disabled in the delayed init
      function) missed to prevent the setup of the delayed init function in
      case the initial tsc calibration failed. This results in the same
      divide by zero bug as we have seen without the tsc disabled check.
      
      Skip the delayed work setup when tsc_khz (the initial calibration
      value) is 0.

       2: detect open syscall event: Ok
       3: detect open syscall event on all cpus: Ok
      [acme@felicio linux]$
      
      Translating C the test does:
      
      1. generates different number of open syscalls on each CPU
         by using sched_setaffinity
      2. Verifies that the expected number of events is generated
         on each CPU
      
      It works as expected.
