      User visible fixes:

       - Record text offset in dso to calculate objdump address, to use with
         modules in addition to vDSO symbol address calculations (Wang Nan)
      
       - Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo)
      
       - Add cpumode to the perf_sample struct, this way we don't need to pass
         the union event to the machine and thread resolving routines, shortening
         function signatures and allowing the future introduction of a way
         to use tracepoint events instead of the unavailable HW cycles counter on
         powerpc guests in perf kvm by just hooking on perf_evsel__parse_sample,
         at the end (Arnaldo Carvalho de Melo)
      
       - Remove/unexport die() related infrastructure, that at some point will
         finally be removed (Arnaldo Carvalho de Melo)
      
       - Adopt linux/stringify.h from the kernel sources, not to touch this
         kernel header from tools/ (Arnaldo Carvalho de Melo)
      
       - Stop using strbuf for things we can instead trivially use libc's asprintf()
         (Arnaldo Carvalho de Melo)
      
       - Ditch tools/lib/util/abspath.c, its only exported function was used at just
         one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo)
      
       - Use strerror_r() in the llvm infrastructure, tread safe, its what is used
         elsewhere in tools/perf/ (Arnaldo Carvalho de Melo)

      ppp: take reference on channels netns · 1f461dcd
      Guillaume Nault 提交于
      Let channels hold a reference on their network namespace.
      Some channel types, like ppp_async and ppp_synctty, can have their
      userspace controller running in a different namespace. Therefore they
      can't rely on them to preclude their netns from being removed from
      under them.

      tools lib traceevent: Remove redundant CPU output · 4f3c8876
      Steven Rostedt 提交于
      Commit a6745330 ("tools lib traceevent: Split pevent_print_event()
      into specific functionality functions") broke apart the function
      pevent_print_event() into three functions.
      
      The first function prints the comm, pid and CPU, the second prints the
      timestamp.
      
      But that commit added the printing of the CPU in the timestamp function,
      which now causes pevent_print_event() to duplicate the CPU output.
      
      Remove the redundant printing of the record's CPU from the timestamp
      function.

      net: phy: at803x: Request 'reset' GPIO only for AT8030 PHY · 9eb13f65
      Sebastian Frias 提交于
      This removes the dependency on GPIOLIB for non faulty PHYs.
      
      Indeed, without this patch, if GPIOLIB is not selected
      devm_gpiod_get_optional() will return -ENOSYS and the driver probe
      call will fail, regardless of the actual PHY hardware.
      
      Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
      only AT8030 presents the issues that commit 13a56b44 ("net: phy:
      at803x: Add support for hardware reset") attempts to work-around by
      using a 'reset' GPIO line.
      
      Hence, only AT8030 should depend on GPIOLIB operating properly.

      at803x: fix reset handling · d57019d1
      Sergei Shtylyov 提交于
      The driver of course "knows" that the chip's reset signal is active low,
      so  it drives the GPIO to 0  to reset the PHY and to 1 otherwise; however
      all this will only work iff the GPIO  is  specified as active-high in the
      device tree!  I think both the driver and the device trees (if there are
      any -- I was unable to find them) need to be fixed in this case...

      hp-wmi: Remove GPS rfkill support via pre-2009 interface · fffcad87
      Maciej S. Szmigiero 提交于
      GPS rfkill support via pre-2009 WMI interface uses hp_wmi_get_sw_state()
      and hp_wmi_get_hw_state() to query its current hard and soft block state,
      respectively.
      
      In hp_wmi_get_sw_state() a mask is calculated which bit should be checked
      in an int value returned by firmware to get current block state: 0x200 <<
      (r * 8) which with r being 3 for GPS results in overflow and mask of zero.
      The same goes for hp_wmi_get_hw_state().
      
      This effectively means that GPS rfkill on this WMI interface is considered
      always both hard and soft blocked.
      
      Unfortunately, later when rfkill subsystem calls hp_wmi_set_block() to sync
      this block to hardware firmware at least on my old nc6400 gets confused and
      sets both hard and soft blocks on WiFi and BT.
      
      This happens for example on hp-wmi module load.
      
      Since due to overflow described above it is dubious that this ever worked
      correctly and HP laptops with modems having GPS support seem to all have
      been released well past year 2009 let's just remove GPS rfkill support via
      pre-2009 WMI interface.

      hp-wmi: fix unregister order in hp_wmi_rfkill_setup() once again · c7805e54
      Maciej S. Szmigiero 提交于
      rfkill registration order in hp_wmi_rfkill_setup() is:
      1) WiFi,
      2) BT,
      3) WWAN,
      5) GPS.
      
      Unregistration when cleaning up on error return should happen in reverse
      order.
      
      This means that: If BT rfkill fails to be allocated we possibly need to
      first unregister WiFi rfkill before destroying it.
      
      The same goes with (WWAN, BT) and (GPS, WWAN) pairs.
      
      Also, if WWAN rfkill fails to register we need to (possibly) unregister BT
      not the GPS one.  And if GPS rfkill fails to register we need to unregister
      WWAN not the BT one.
      
      We never need to unregister GPS rfkill here since if GPS rfkill
      registration succeeds this function returns without error so no cleanup is
      necessary.

      Similarly to Dell Vostro V131, Dell Inspiron M5110 also requires an

      dell-wmi: properly process Dell Instant Launch hotkey · 13f5059a
      Michał Kępień 提交于
      On models on which an SMBIOS request needs to be issued in order for WMI
      events to be generated, pressing the Dell Instant Launch hotkey does not
      raise an i8042 interrupt - only a WMI event is generated (0xe025 on Dell
      Vostro V131).  As that WMI event is the only way the kernel will be
      notified about pressing the Dell Instant Launch hotkey on such machines,
      the relevant keymap entry has to be changed to a KE_KEY one.  However,
      the same WMI event should still be ignored on machines which do not
      require an SMBIOS request for enabling WMI, so filter it conditionally
      in dell_wmi_process_key().

      dell-wmi: enable receiving WMI events on Dell Vostro V131 · e09c4d5b
      Michał Kępień 提交于
      On some laptop models (e.g. Dell Vostro V131), WMI events are not
      generated until a specific SMBIOS request is issued to register an event
      listener [1].  As there seems to be no ACPI method or SMBIOS request to
      determine without possible side effects whether a given machine needs to
      issue this SMBIOS request in order to receive WMI events, DMI matching
      is used to whitelist the models which need it.
