      hrtimers: Fix typo causing erratic timers · 90ff1f30
      Thomas Gleixner authored
      commit 9ec26907
      
       ("timerfd: Manage cancelable timers in timerfd")
      introduced a CONFIG_HIGHRES_TIMERS (should be CONFIG_HIGH_RES_TIMERS)
      typo, which caused applications depending on CLOCK_REALTIME timers to
      become sluggy due to the fact that the time base of the realtime
      timers was not updated when the wall clock time was set.
      
      This causes anything from 100% CPU use for some applications to odd
      delays and hickups.

      It occurs because we are able to change the slave configuarion of a bond while
      the bond interface is down.  The bonding driver initializes some data structures
      only after its ndo_open routine is called.  Among them is the initalization of
      the alb tx and rx hash locks.  So if we add or remove a slave without first
      opening the bond master device, we run the risk of trying to lock/unlock a
      spinlock that has garbage for data in it, which results in our above softlock.
      
      Note that sometimes this works, because in many cases an unlocked spinlock has
      the raw_lock parameter initialized to zero (meaning that the kzalloc of the
      net_device private data is equivalent to calling spin_lock_init), but thats not
      true in all cases, and we aren't guaranteed that condition, so we need to pass
      the relevant spinlocks through the spin_lock_init function.
      
      Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to
      the ndo_init path, so they are ready for use by the bond_store_slaves path.
      
      Change notes:
      v2) Based on conversation with Jay and Nicolas it seems that the ability to
      enslave devices while the bond master is down should be safe to do.  As such
      this is an outlier bug, and so instead we'll just initalize the errant spinlocks
      in the init path rather than the open path, solving the problem.  We'll also
      remove the warnings about the bond being down during enslave operations, since
      it should be safe
      
      v3) Fix spelling error

      net: hold rtnl again in dump callbacks · 2907c35f
      Eric Dumazet authored
      Commit e67f88dd
      
       (dont hold rtnl mutex during netlink dump callbacks)
      missed fact that rtnl_fill_ifinfo() must be called with rtnl held.
      
      Because of possible deadlocks between two mutexes (cb_mutex and rtnl),
      its not easy to solve this problem, so revert this part of the patch.
      
      It also forgot one rcu_read_unlock() in FIB dump_rules()
      
      Add one ASSERT_RTNL() in rtnl_fill_ifinfo() to remind us the rule.

      Tested to detect the card, MAC and serdes, not tested with link at the
      moment since I have no fiber switch here. I did not add new constants to
      the pci_ids.h header file since these constants are used only here.

      sch_sfq: fix peek() implementation · 07bd8df5
      Eric Dumazet authored
      Since commit eeaeb068
      
       (sch_sfq: allow big packets and be fair),
      sfq_peek() can return a different skb that would be normally dequeued by
      sfq_dequeue() [ if current slot->allot is negative ]
      
      Use generic qdisc_peek_dequeued() instead of custom implementation, to
      get consistent result.

      isdn: netjet - blacklist Digium TDM400P · 367bbf2a

      [2nd try ... 1st attempt didn't make it to netdev mailing list]
      
      A quick google search reveals that people with this card are blacklisting it
      in the initramfs and in the module blacklist based on a statement that it
      is unsupported. Since the older Digium is also unsupported I'm pretty
      confident that this newer card is also not supported.

      via-velocity: don't annotate MAC registers as packed · d10358de
      Ulrich Hecht authored
      On ARM, memory accesses through packed pointers behave in unexpected
      ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163
      
      
      for discussion.
      
      In this particular case, 32-bit I/O registers are accessed bytewise,
      causing incorrect setting of the DMA address registers which in turn
      leads to an error interrupt storm that brings the system to a halt.
      
      Since the mac_regs structure does not need any packing anyway, this patch
      simply removes the attribute to fix the issue.

      If an ASCONF chunk is outstanding, then the following ASCONF

      the asoc, we forget to free the ASCONF queue at the same time,
      this will cause memory leak.

      Philip Rakity authored
      
      
      CMD19 -- The offical way to validate bus widths from the JEDEC spec
      does not work on all platforms.  Some platforms that use PCI/PCIe
      to connect their SD controllers are known to fail.
      
      If the quirk MMC_BUS_WIDTH_TEST is not defined we try to figure out
      the bus width by reading the ext_csd at different bus widths and
      compare this against the ext_csd read in 1 bit mode.  If no ext_csd
      is available we default to 1 bit operations.
      
      Code has been tested on mmp2 against 8 bit eMMC and Transcend 2GB
      card that is known to not work in 4 bit mode.  The physical pins
      on the card are not present to support 4 bit operation.

      Jean Delvare authored
      
      
      The abituguru drivers are only built on X86, where DMI support is now
      enabled by default. So let these drivers depend on DMI, for the
      following gains:
      * Robustness and safety. Detection of these devices is weak and uses
        non-standard methods, it should really be limited to Abit boards
        unless the user explicitly asks otherwise.
      * Code simplicity. The code is easier to read without ifdefs.
      * Better build testing coverage. Now there's only one way to build the
        drivers, so no risk of build failure on exotic systems.
