      driver core: correct device's shutdown order · 52cdbdd4
      Grygorii Strashko authored
      Now device's shutdown sequence is performed in reverse order of their
      registration in devices_kset list and this sequence corresponds to the
      reverse device's creation order. So, devices_kset data tracks
      "parent<-child" device's dependencies only.
      
      Unfortunately, that's not enough and causes problems in case of
      implementing board's specific shutdown procedures. For example [1]:
      "DRA7XX_evm uses PCF8575 and one of the PCF output lines feeds to
      MMC/SD and this line should be driven high in order for the MMC/SD to
      be detected. This line is modelled as regulator and the hsmmc driver
      takes care of enabling and disabling it. In the case of 'reboot',
      during shutdown path as part of it's cleanup process the hsmmc driver
      disables this regulator. This makes MMC boot not functional."
      
      To handle this issue the .shutdown() callback could be implemented
      for PCF8575 device where corresponding GPIO pins will be configured to
      states, required for correct warm/cold reset. This can be achieved
      only when all .shutdown() callbacks have been called already for all
      PCF8575's consumers. But devices_kset is not filled correctly now:
      
      devices_kset: Device61 4e000000.dmm
      devices_kset: Device62 48070000.i2c
      devices_kset: Device63 48072000.i2c
      devices_kset: Device64 48060000.i2c
      devices_kset: Device65 4809c000.mmc
      ...
      devices_kset: Device102 fixedregulator-sd
      ...
      devices_kset: Device181 0-0020 // PCF8575
      devices_kset: Device182 gpiochip496
      devices_kset: Device183 0-0021 // PCF8575
      devices_kset: Device184 gpiochip480
      
      As can be seen from above .shutdown() callback for PCF8575 will be called
      before its consumers, which, in turn means, that any changes of PCF8575
      GPIO's pins will be or unsafe or overwritten later by GPIO's consumers.
      The problem can be solved if devices_kset list will be filled not only
      according device creation order, but also according device's probing
      order to track "supplier<-consumer" dependencies also.
      
      Hence, as a fix, lets add devices_kset_move_last(),
      devices_kset_move_before(), devices_kset_move_after() and call them
      from device_move() and also add call of devices_kset_move_last() in
      really_probe(). After this change all entries in devices_kset will
      be sorted according to device's creation ("parent<-child") and
      probing ("supplier<-consumer") order.
      
      devices_kset after:
      devices_kset: Device121 48070000.i2c
      devices_kset: Device122 i2c-0
      ...
      devices_kset: Device147 regulator.24
      devices_kset: Device148 0-0020
      devices_kset: Device149 gpiochip496
      devices_kset: Device150 0-0021
      devices_kset: Device151 gpiochip480
      devices_kset: Device152 0-0019
      ...
      devices_kset: Device372 fixedregulator-sd
      devices_kset: Device373 regulator.29
      devices_kset: Device374 4809c000.mmc
      devices_kset: Device375 mmc0

      Toshi explains:
      
      "No, the default values need to be set to the fallback types,
       i.e. minimal supported mode.  For WC and WT, UC is the fallback type.
      
       When PAT is disabled, pat_init() does update the tables below to
       enable WT per the default BIOS setup.  However, when PAT is enabled,
       but CPU has PAT -errata, WT falls back to UC per the default values."

      The CQM task events are not safe to be called from within interrupt
      context because they require performing an IPI to read the counter value
      on all sockets. And performing IPIs from within IRQ context is a
      "no-no".
      
      Make do with the last read counter value currently event in
      event->count when we're invoked in this context.

      Pull libata fixes from Tejun Heo:
       "A couple important fixes.
      
         - A block layer change which removed restriction on max transfer size
           led to silent data corruption on some devices.  A new quirk is
           added to restore the old size limit for the reported device.  If it
           gets reported on more devices, we might have to consider restoring
           the restriction for ATA devices by default.
      
         - There finally is a SSD which is confirmed to cause data corruption
           on TRIM regardless of which flavor is used.  A new quirk is added
           and the device is blacklisted

      ftrace: Fix breakage of set_ftrace_pid · e3eea140
      Steven Rostedt (Red Hat) authored
      Commit 4104d326 ("ftrace: Remove global function list and call function
      directly") simplified the ftrace code by removing the global_ops list with a
      new design. But this cleanup also broke the filtering of PIDs that are added
      to the set_ftrace_pid file.
      
      Add back the proper hooks to have pid filtering working once again.

      Devices may declare more LEDs than what is known to input-leds
      (HID does this for some devices). Instead of showing ugly warnings
      on connect and, even worse, oopsing on disconnect, let's simply
      ignore LEDs that are not known to us.
