      usb: fixes for v3.16-rc4
      
      A few more fixes for this RC cycle. There's a revert of a previous patch
      which ended up being the wrong version, so we reverted that commit and
      applied a better fix.
      
      CPPI41 got a race condition fix which was found by Thomas Gleixner.
      
      The MSM PHY driver got a runtime pm usage fix so that it wouldn't
      kill the PHY while it was still being used.
      
      We also have a fix for a panic caused when removing musb_am335x driver.
      
      Other than that, a few other minor fixes.

      usb: musb: dsps: fix the base address for accessing the mode register · 80356913
      Lothar Waßmann authored
      commit 943c1397 "usb: musb: dsps: implement ->set_mode()"
      should have made it possible to use the driver with boards that have
      the USBID pin unconnected. This doesn't actually work, since the
      driver uses the wrong base address to access the mode register.
      Furthermore it uses different base addresses in different places to
      access the same register (phy_utmi).

      tools: ffs-test: fix header values endianess · f35f7124
      Michal Nazarewicz authored
      It appears that no one ever run ffs-test on a big-endian machine,
      since it used cpu-endianess for fs_count and hs_count fields which
      should be in little-endian format.  Fix by wrapping the numbers in
      cpu_to_le32.

      usb: phy: msm: Do not do runtime pm if the phy is not idle · 508ccea1
      Srinivas Kandagatla authored
      Use case is when the phy is configured in host mode and a usb device is
      attached to board before bootup. On bootup, with the existing code and
      runtime pm enabled, the driver would decrement the pm usage count
      without checking the current state of the phy. This pm usage count
      decrement would trigger the runtime pm which than would abort the
      usb enumeration which was in progress. In my case a usb stick gets
      detected and then immediatly the driver goes to low power mode which is
      not correct.

      usb: musb: Ensure that cppi41 timer gets armed on premature DMA TX irq · c58d80f5
      Thomas Gleixner authored
      Some TI chips raise the DMA complete interrupt before the actual
      transfer has been completed. The code tries to busy wait for a few
      microseconds and if that fails it arms an hrtimer to recheck. So far
      so good, but that has the following issue:
      
      CPU 0					CPU1
      
      start_next_transfer(RQ1);
      
      DMA interrupt
        if (premature_irq(RQ1))
          if (!hrtimer_active(timer))
             hrtimer_start(timer);
      
      hrtimer expires
        timer->state = CALLBACK_RUNNING;
        timer->fn()
          cppi41_recheck_tx_req()
            complete_request(RQ1);
            if (requests_pending())
              start_next_transfer(RQ2);
      
      					DMA interrupt
      					  if (premature_irq(RQ2))
      					    if (!hrtimer_active(timer))
      					       hrtimer_start(timer);
        timer->state = INACTIVE;
      
      The premature interrupt of request2 on CPU1 does not arm the timer and
      therefor the request completion never happens because it checks for
      !hrtimer_active(). hrtimer_active() evaluates:
      
        timer->state != HRTIMER_STATE_INACTIVE
      
      which of course evaluates to true in the above case as timer->state is
      CALLBACK_RUNNING.
      
      That's clearly documented:
      
       * A timer is active, when it is enqueued into the rbtree or the
       * callback function is running or it's in the state of being migrated
       * to another cpu.
      
      But that's not what the code wants to check. The code wants to check
      whether the timer is queued, i.e. whether its armed and waiting for
      expiry.
      
      We have a helper function for this: hrtimer_is_queued(). This
      evaluates:
      
        timer->state & HRTIMER_STATE_QUEUED
      
      So in the above case this evaluates to false and therefor forces the
      DMA interrupt on CPU1 to call hrtimer_start().
      
      Use hrtimer_is_queued() instead of hrtimer_active() and evrything is
      good.

      usb: musb: Fix panic upon musb_am335x module removal · 7adb5c87
      Ezequiel Garcia authored
      At probe time, the musb_am335x driver register its childs by
      calling of_platform_populate(), which registers all childs in
      the devicetree hierarchy recursively.
      
      On the other side, the driver's remove() function uses of_device_unregister()
      to remove each child of musb_am335x's.
      
      However, when musb_dsps is loaded, its devices are attached to the musb_am335x
      device as musb_am335x childs. Hence, musb_am335x remove() will attempt to
      unregister the devices registered by musb_dsps, which produces a kernel panic.
      
      In other words, the childs in the "struct device" hierarchy are not the same
      as the childs in the "devicetree" hierarchy.
      
      Ideally, we should enforce the removal of the devices registered by
      musb_am335x *only*, instead of all its child devices. However, because of the
      recursive nature of of_platform_populate, this doesn't seem possible.
      
      Therefore, as the only solution at hand, this commit disables musb_am335x
      driver removal capability, preventing it from being ever removed. This was
      originally suggested by Sebastian Siewior:
      
      https://www.mail-archive.com/linux-omap@vger.kernel.org/msg104946.html
      
      And for reference, here's the panic upon module removal:
      
      musb-hdrc musb-hdrc.0.auto: remove, state 4
      usb usb1: USB disconnect, device number 1

      Even though usb_functionfs_descs_head structure is now deprecated,
      it has been used by some user space tools.  Its removel in commit
      [ac8dde11: “Add flags to descriptors block”] was an oversight
      leading to build breakage for such tools.
      
      Bring it back so that old user space tools can still be build
      without problems on newer kernel versions.

      2.2, xhci_resume function calls usb_hcd_resume_root_hub to queue two
      workqueue items to resume usb2&usb3 roothub devices.
      
      2.3, Call suspend callbacks of devices.
      
      2.3.1, All suspend callbacks of all hcd's children, including
      roothub devices are called.
      
      2.3.2, Finally, hcd_pci_suspend callback is called.
      
      Due to workqueue threads were already frozen in step 1, the workqueue
      items can't be scheduled, and the roothub devices can't be resumed in
      this flow. The HCD_FLAG_WAKEUP_PENDING flag which is set in
      usb_hcd_resume_root_hub won't be cleared. Finally,
      hcd_pci_suspend will return -EBUSY, and system suspend fails.
      
      The reason why this issue doesn't show up very often is due to that
      choose_wakeup will be called in step 2.3.1. In step 2.3.1, if
      udev->do_remote_wakeup is not equal to device_may_wakeup(&udev->dev), then
      udev will resume to RPM active for changing the wakeup settings. This
      has been a lucky hit which hides this issue.
      
      For some special xHCI controllers which have no USB2 port, then roothub
      will not match hub driver due to probe failed. Then its
      do_remote_wakeup will be set to zero, and we won't be as lucky.
      
      xhci driver doesn't need to resume roothub devices everytime like in
      the above case. It's only needed when there are pending event TRBs.
      
      This patch should be back-ported to kernels as old as 3.2, that
      contains the commit f69e3120

      xhci: clear root port wake on bits if controller isn't wake-up capable · ff8cbf25
      Lu Baolu authored
      When xHCI PCI host is suspended, if do_wakeup is false in xhci_pci_suspend,
      xhci_bus_suspend needs to clear all root port wake on bits. Otherwise some Intel
      platforms may get a spurious wakeup, even if PCI PME# is disabled.
      
      This patch should be back-ported to kernels as old as 2.6.37, that
      contains the commit 9777e3ce

      xhci: correct burst count field for isoc transfers on 1.0 xhci hosts · 3213b151
      Mathias Nyman authored
      The transfer burst count (TBC) field in xhci 1.0 hosts should be set
      to the number of bursts needed to transfer all packets in a isoc TD.
      Supported values are 0-2 (1 to 3 bursts per service interval).
      
      Formula for TBC calculation is given in xhci spec section 4.11.2.3:
      TBC = roundup( Transfer Descriptor Packet Count / Max Burst Size +1 ) - 1
      
      This patch should be applied to stable kernels since 3.0 that contain
      the commit 5cd43e33

      xhci: Use correct SLOT ID when handling a reset device command · 6fcfb0d6
      Mathias Nyman authored
      Command completion events normally include command completion status,
      SLOT_ID, and a pointer to the original command. Reset device command
      completion SLOT_ID may be zero according to xhci specs 4.6.11.
      
      VIA controllers set the SLOT_ID to zero, triggering a WARN_ON in the
      command completion handler.
      
      Use the SLOT ID found from the original command instead.
      
      This patch should be applied to stable kernels since 3.13 that contain
      the commit 20e7acb1
      "xhci: use completion event's slot id rather than dig it out of command"

      Pull i2c new drivers from Wolfram Sang:
       "Here is a pull request from i2c hoping for the "new driver" rule.
      
        Originally, I wanted to send this request during the merge window, but
        code checkers with very recent additions complained, so a few fixups
        were needed.  So, some more time went by and I merged rc1 to get a
        stable base"
      
      So the "new driver" rule is really about drivers that people absolutely
      need for the kernel to work on new hardware, which is not so much the
      case for i2c.  So I considered not pulling this, but eventually
      relented.
      
      Just for FYI: the whole (and only) point of "new drivers" is not that
      new drivers cannot regress things (they can, and they have - by
      triggering badly tested code on machines that never triggered that code
      before), but because they can bring to life machines that otherwise
      wouldn't be useful at all without the drivers.
      
      So the new driver rule is for essential things that actual consumers
      would care about, ie devices like networking or disk drivers that matter
      to normal people (not server people - they run old kernels anyway, so
      mainlining new drivers is irrelevant for them).

      Pull ACPI and power management fixes from Rafael Wysocki:
       "These are fixes mostly (ia64 regression related to the ACPI
        enumeration of devices, cpufreq regressions, fix for I2C controllers
        included in Intel SoCs, mvebu cpuidle driver fix related to sysfs)
        plus additional kernel command line arguments from Kees to make it
        possible to build kernel images with hibernation and the kernel
        address space randomization included simultaneously, a new ACPI
        battery driver quirk for a system with a broken BIOS and a couple of
        ACPI core cleanups.
      
        Specifics:
      
         - Fix for an ia64 regression introduced during the 3.11 cycle by a
           commit that modified the hardware initialization ordering and made
           device discovery fail on some systems.
      
         - Fix for a build problem on systems where the cpufreq-cpu0 driver is
           built-in and the cpu-thermal driver is modular from Arnd Bergmann.
      
         - Fix for a recently introduced computational mistake in the
           intel_pstate driver that leads to excessive rounding errors from
           Doug Smythies.
      
         - Fix for a failure code path in cpufreq_update_policy() that fails
           to unlock the locks acquired previously from Aaron Plattner.
      
         - Fix for the cpuidle mvebu driver to use shorter state names which
           will prevent the sysfs interface from returning mangled strings.
           From Gregory Clement.
      
         - ACPI LPSS driver fix to make sure that the I2C controllers included
           in BayTrail SoCs are not held in the reset state while they are
           being probed from Mika Westerberg.
      
         - New kernel command line arguments making it possible to build
           kernel images with hibernation and kASLR included at the same time
           and to select which of them will be used via the command line (they
           are still functionally mutually exclusive, though).  From Kees
           Cook.
      
         - ACPI battery driver quirk for Acer Aspire V5-573G that fails to
           send battery status change notifications timely from Alexander
           Mezin.
      
         - Two ACPI core cleanups from Christoph Jaeger and Fabian Frederick"

      Pull block fixes from Jens Axboe:
       "A smaller collection of fixes for the block core that would be nice to
        have in -rc2.  This pull request contains:
      
         - Fixes for races in the wait/wakeup logic used in blk-mq from
           Alexander.  No issues have been observed, but it is definitely a
           bit flakey currently.  Alternatively, we may drop the cyclic
           wakeups going forward, but that needs more testing.
      
         - Some cleanups from Christoph.
      
         - Fix for an oops in null_blk if queue_mode=1 and softirq completions
           are used.  From me.
      
         - A fix for a regression caused by the chunk size setting.  It
           inadvertently used max_hw_sectors instead of max_sectors, which is
           incorrect, and causes hangs on btrfs multi-disk setups (where hw
           sectors apparently isn't set).  From me.
      
         - Removal of WQ_POWER_EFFICIENT in the kblockd creation.  This was a
           recent addition as well, but it actually breaks blk-mq which relies
           on strict scheduling.  If the workqueue power_efficient mode is
           turned on, this breaks blk-mq.  From Matias.
      
         - null_blk module parameter description fix from Mike"
