      usb: musb: finish suspend/reset work independently from musb_hub_control() · 8ed1fb79
      Daniel Mack authored
      Currently, resume and reset is completed when the USB core calls back
      the root hub, asking for the port's state. This results in
      unpredictable timing of state assertion, which in turn renders some
      USB devices unusable after resume.
      
      Fix this by moving the logic to end the reset and suspend state out of
      musb_hub_control() into separate functions called from delayed workers.
      GetPortStatus only reports the current state now, without taking any
      real action.
      
      The rh_timeout variable is kept in order to define a minimum time gap
      between reset and resume only.
      
      FWIW, in my case, a Verbatim "STORE N GO" mass storage device won't
      resume cleanly without this patch.

      Subject: [PATCH] usb/gadget: should use u16 type variable to store MaxPower
      
      The MaxPower field is of u16 type. So using u8 type variable can break
      data (high byte lost).

      usb: phy: am335x: Enable USB remote wakeup using PHY wakeup · 2fc711d7
      George Cherian authored
      USB remote wakeup using PHY wakeup is supported only in standby mode.
      Enabling the PHY_WKUP will break DS0 mode of system suspend.
      If the same is enabled while entering DS0, AM33xx never stays in DS0,
      it returns immediately from DS0. By default make the PHY wakeup
      disabled, using sysfs entry enable the same manually to get
      the remote wakeup working from standby.
      
      echo enabled > /sys/bus/platform/device/<usb phy id>/power/wakeup
      This will enable the PHY wakeup while going to standby.
      
      PHY wakeup feature is required to wakeup  the system from standby
      state. Since AM33xx has a bug in which PHY wakeup should not
      be enabled while entering DS0, disable the same by default.
      A user wishing to use USB wakeup from standby mode need to enable
      the same using the sysfs entries.
      
      Also remove am335x_phy_runtime_(suspend/resume) this driver doesnot really
      enable/disable the clocks to the PHY.
      Add am335x_phy_(suspend/resume) and use the same for enabling the PHY_WKUP.

      null_blk: mem garbage on NUMA systems during init · 57053d8c
      Matias Bjorling authored
      For NUMA systems, initializing the blk-mq layer and using per node hctx.
      We initialize submit queues to 1, while blk-mq nr_hw_queues is
      initialized to the number of NUMA nodes.
      
      This makes the null_init_hctx function overwrite memory outside of what
      it allocated.  In my case it lead to writing garbage into struct
      request_queue's mq_map.

      13) Procfs entry leak in xt_hashlimit, from Sergey Popovich.
      
      14) IPv6 routes that are no cached routes should not count against the
          garbage collection limits.  We had this almost right, but were
          missing handling addrconf generated routes properly.  From Hannes

      igb: Fix for issue where values could be too high for udelay function. · df29df92
      Carolyn Wyborny authored
      This patch changes the igb_phy_has_link function to check the value of the
      parameter before deciding to use udelay or mdelay in order to be sure that
      the value is not too high for udelay function.

      If the vsi->tx_rings structure is NULL we don't want to panic.
