       "Here are two USB bugfixes for your 3.6-rc7 tree.
      
        The OHCI fix has been reported a number of times and is a regression
        from 3.5, and the patch that causes the regression was on the way to
        the -stable trees before I was reminded (again) that this fix needed
        to get to your tree soon.
      
        The host controller bugfix was reported in older kernels as being
        pretty easy to trigger, and has been tested by Red Hat and their
        customers.
      
        Both have been in the usb-next branch in the -next tree for a while
        now, I just cherry-picked them out to get to you in time for the 3.6
        release.

                      causing the number of pages per dimm (an unsigned value)

      USB: Fix race condition when removing host controllers · 0d00dc26
      Alan Stern authored
      This patch (as1607) fixes a race that can occur if a USB host
      controller is removed while a process is reading the
      /sys/kernel/debug/usb/devices file.
      
      The usb_device_read() routine uses the bus->root_hub pointer to
      determine whether or not the root hub is registered.  The is not a
      valid test, because the pointer is set before the root hub gets
      registered and remains set even after the root hub is unregistered and
      deallocated.  As a result, usb_device_read() or usb_device_dump() can
      access freed memory, causing an oops.
      
      The patch changes the test to use the hcd->rh_registered flag, which
      does get set and cleared at the appropriate times.  It also makes sure
      to hold the usb_bus_list_lock mutex while setting the flag, so that
      usb_device_read() will become aware of new root hubs as soon as they
      are registered.

      md/raid10: fix "enough" function for detecting if array is failed. · 80b48124
      NeilBrown authored
      The 'enough' function is written to work with 'near' arrays only
      in that is implicitly assumes that the offset from one 'group' of
      devices to the next is the same as the number of copies.
      In reality it is the number of 'near' copies.
      
      So change it to make this number explicit.
      
      This bug makes it possible to run arrays without enough drives
      present, which is dangerous.
      It is appropriate for an -stable kernel, but will almost certainly
      need to be modified for some of them.

      Pull more networking fixes from David Miller:
      
       1) Eric Dumazet discovered and fixed what turned out to be a family of
          bugs.  These functions were using pskb_may_pull() which might need
          to reallocate the linear SKB data buffer, but the callers were not
          expecting this possibility.  The callers have cached pointers to the
          packet header areas, and would need to reload them if we were to
          continue using pskb_may_pull().
      
          So they could end up reading garbage.
      
          It's easier to just change these RAW4/RAW6/MIP6 routines to use
          skb_header_pointer() instead of pskb_may_pull(), which won't modify
          the linear SKB data area.
      
       2) Dave Jone's syscall spammer caught a case where a non-TCP socket can
          call down into the TCP keepalive code.  The case basically involves
          creating a raw socket with sk_protocol == IPPROTO_TCP, then calling
          setsockopt(sock_fd, SO_KEEPALIVE, ...)
      
          Fixed by Eric Dumazet.
      
       3) Bluetooth devices do not get configured properly while being powered
          on, resulting in always using legacy pairing instead of SSP.  Fix
          from Andrzej Kaczmarek.
      
       4) Bluetooth cancels delayed work erroneously, put stricter checks in
          place.  From Andrei Emeltchenko.
      
       5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in
          cfg80211, from Luis R.  Rodriguez.
      
       6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach.
      
       7) Missing module license in bcm87xx driver, from Peter Huewe.
      
       8) Team driver can lose port changed events when adding devices to a
          team, fix from Jiri Pirko.
      
       9) Fix endless loop when trying ot unregister PPPOE device in zombie
          state, from Xiaodong Xu.
      
      10) batman-adv layer needs to set MAC address of software device
          earlier, otherwise we call tt_local_add with it uninitialized.
      
      11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but
          that doesn't program the device properly.  From Marek Vasut.

      c/r: prctl: fix build error for no-MMU case · be8cfc4a
      Mark Salter authored
      Commit 1ad75b9e ("c/r: prctl: add minimal address test to
      PR_SET_MM") added some address checking to prctl_set_mm() used by
      checkpoint-restore.  This causes a build error for no-MMU systems:
      
         kernel/sys.c: In function 'prctl_set_mm':
         kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function)
      
      The test for mmap_min_addr doesn't make a lot of sense for no-MMU code
      as noted in commit 6e141546 ("NOMMU: Optimise away the
      {dac_,}mmap_min_addr tests").
      
      This patch defines mmap_min_addr as 0UL in the no-MMU case so that the
      compiler will optimize away tests for "addr < mmap_min_addr".

      lib/flex_proportions.c: fix corruption of denominator in flexible proportions · b5bd6a0e
      Jan Kara authored
      When racing with CPU hotplug, percpu_counter_sum() can return negative
      values for the number of observed events.
      
      This confuses fprop_new_period(), which uses unsigned type and as a
      result number of events is set to big *positive* number.  From that
      moment on, things go pear shaped and can result e.g.  in division by
      zero as denominator is later truncated to 32-bits.
      
      This bug causes a divide-by-zero oops in bdi_dirty_limit() in Borislav's
      3.6.0-rc6 based kernel.
      
      Fix the issue by using a signed type in fprop_new_period().  That makes
      us bail out from the function without doing anything (mistakenly)
      thinking there are no events to age.  That makes aging somewhat
      inaccurate but getting accurate data would be rather hard.

      sb_edac: Avoid overflow errors at memory size calculation · deb09dda
      Mauro Carvalho Chehab authored
      Sandy bridge EDAC is calculating the memory size with overflow.
      Basically, the size field and the integer calculation is using 32 bits.
      More bits are needed, when the DIMM memories have high density.
      
      The net result is that memories are improperly reported there, when
      high-density DIMMs are used:
      
      EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 0, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
      EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 1, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
      
      As the number of pages value is handled at the EDAC core as unsigned
      ints, the driver shows the 16 GB memories at sysfs interface as 16760832
      MB! The fix is simple: calculate the number of pages as unsigned 64-bits
      integer.
      
      After the patch, the memory size (16 GB) is properly detected:
      
      EDAC DEBUG: in drivers/edac/sb_edac.c, line at 592: mc#0: channel 0, dimm 0, 16384 Mb (4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800

      sh: pfc: Fix up GPIO mux type reconfig case. · 16d74ebe
      Paul Mundt authored
      Some drivers need to switch pin states between GPIO and pin function at
      runtime, which was inadvertently broken in the pinctrl driver for GPIOs
      being bound to a specific direction.
      
      This fixes up the request path to ensure that previously configured GPIOs
      don't cause us to inadvertently error out with an unsupported mux on
      reconfig, which in practice is primarily aimed at trapping pull-up/down
      users that have yet to be implemented under the new API.
      
      Fixes up regressions in the TPU PWM driver, amongst others.

      John W. Linville says:
      
      ====================
      Please pull this last(?) batch of fixes intended for 3.6...
      
      For the Bluetooth bits, Gustavo says this:
      
      "Here goes probably my last update to 3.6. It includes the two patches
      you were ok last week(from Andrzej Kaczmarek), those are critical
      ones, and two other fixes one for a system crash and the other for
      a missing lockdep annotation."
      
      The referenced fixes from Andrzej prevent attempts to configure devices
      that are powered-off.
      
      Along with the Bluetooth fixes, there are a couple of 802.11 fixes.
      Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an
      interrupt twice.  Luis R. Rodriguez provides a fix for a possible
      circular lock dependency in the cfg80211 regulatory enforcement code.
      
      All of these have been in linux-next for a few days.  I hope they are
      not too late to make the 3.6 release!
